Last month I spent about 2 days figuring this out on my newly built PC. I had random black screens and dead PC during gaming especially. While browsing solutions online, I remember watching one of your previous videos that actually talked about the compatability issue of XMP and 4 sticks DDR5 as well. That inspired me. I have 2 * 2 * 32 GB Fury stick kit + 4090 + Z790 Hero MOBO. You helped me locate the exact problem: XMP. I ran a bunch of memtest and found that none of Auto, Manual + some recommended tuning, and XMP 1 worked at all. After upgrading the BIOS to the lastest version (08xx?), I found that only XMP2 at advertised rate or Manual at factory rate worked. After setting to XMP2, all problems were gone and my PC never worked this smoothly before. Your video is EXACTLY the tour I had been through. I really hoped this life saver had come a bit earlier. Great review!
@@NearMedia Yes sir this is the latest version by now. At the time I checked that out, 0904 wasn't available yet. Btw, 0816 works perfectly and I am not bothered to try 0904 for potentially new trash to deal with
@@NearMedia Yes sir. All tests were passed. Practically, it's been about 20 days with no black screen. No freeze. No sysfaults. Nothing. I assume it's long enough to be firm about it now.
4xDDR5 lowers the supported speeds. Unfortunately XMP/EXPO counts as memory overclocking so there 's CPUs that won't handle even 2xDDR5 at the advertised speeds, while over boards manage 4 DIMM configurations. I read the Gigabyite board notes and they were talking about their memory configuration avoiding drawbacks of daisy chaining. There's plenty of small server boards with ECC on the AMD side aimed at the small server market.
I just want to say thank you for this video! The information I attained from it is monumental when it comes to understanding how to approach RAM when building an enthusiast PC and overclocking as a whole and all of the specifics that need to be considered when choosing between speed, capacity and 2 or 4 sticks.
first of all, i was a bit scared away from a 1h41min video, but it was one of the best times spend to understand a lot of topics about memory better, than ever before. This will scale through many builds in the future!!!!
The ultimate guide indeed. This video is pure gold, countering all the misinformation and explaining clearly why 4 -v- 2 XMP stick configuratons may not give the expected results. Thank you!
finished the build for my wife yesterday: 13900K on a MSI Z790 Carbon Wifi with 4x 16GB Corsair (CMT32GX5M2X6200C36, 6200MHz CL36, Hynix M) running absolutly rock solid in XMP @ 6200 with latest BIOS (7D89v15). Just turned on XMP1, expected a boot loop, but it simply worked with all stress tests. Fingers crossed. Very happy.
I finally figured out how to use 4 sticks of DDR5 on a Z790 Dark Hero. This video shows you how, but it doesn't understand what it shows you. I had the same problem going from 64gb of 6400 ram (2 sticks) to 128gb of 6400 ram (4 sticks). I began only being able to run it with optimized defaults after returning my original purchase of the extra two sticks and exchanging it. The return wasn't necessary and didn't work. After a couple of UA-cam videos that said that I can just reset the BIOS, I could run it at the optimized default settings. It ran, but at 4200. After watching this video, I was inadvertently shown where you can see the true speed of the ram and that the speed printed on the box is the overclock speed. On the EZ Mode settings above the X.M.P., it will tell you the speed of the ram the motherboard sees. Do not change the setting in EZ Mode, leave it disabled. Go back to Advanced Mode and leave everything to Auto. Drop down to Memory controller and change the frequency to 4800. Don't touch anything else. Save settings and reboot. It will reboot with the new settings. Yes, it runs at 6400 when I use 2 sticks. This does not apply with 4 sticks. I know that at 4200 my system is very stable. It is a bit faster at 4800, but I need to use it for a while to test how stable it actually is. I do know that I couldn't get it to boot when I used a higher speed, and the video didn't turn on. On the Dark Hero, I have to remove the CMOS battery to reset the BIOS. This is a pain. Anyway, I am up now. If I experience anymore glitches, I know I can reset the BIOS to its default settings and run without issues. I bought the extra ram because 64gb wasn't enough ram and I crashed when I had too many tabs open in Microsoft Edge. With 128gb of ram, or 4 sticks, I am more stable and don't crash. Anyway, I hope this helps.
I was just about to buy parts for my first build - this was the perfect course on what to look for and more importantly why! Thanks for doing it. I learned a lot and hopefully saved serious time and money!
Man! What a greatly informative, interesting, and helpful video!! This clarified a bunch of questions I’ve had for years. Thank you for such a thoughtful interview (with perfect questions) with just the right person.
wow... I am building a PC after many many years and had so many questions regarding RAM and XMP. Your video answered almost every single question that had come to my mind and then some. I could not hit the Subscribe button fast enough. Bless you for such a detailed and informative video
Any video with JJ is gonna be a banger, definite knowledge being dropped on ya. Third of the way through the video and I'm hooked. Thanks guys for the collab.
There should be a notice on the box! I bought two 2x16GB Corsair Vengeance RGB 6000 kits and could not get a proper overclock no matter what I did. 4800 is just too too slow for me! Luckily I was able to return them and I bought a single 2x32GB G.Skill Trident Z5 RGB 6400 kit instead.
Kingpin did an interview explaining these things not long ago. I can't find it, otherwise I would link it. He said the same thing a lot quicker and clearer than this guy. Basically, Kingpin was saying his preference in motherboards for overlocking stability was for only 2 DIMM slots. The more slots you add, the more noise potential you introduce. The more noise, the slower the speed potential. Same with DIMMS - single sided DIMMs (or single-rank as they are also called) are capable of higher speeds than dual-rank DIMMS. (double sided). The fewer IC's on a DIMM the more stable it could/should be.
I think that 'rank' can better be explained by considering the extra capacitance added to the address and data lines if the sticks are double sided (current 32gb per stick!). This extra capacitance slows down the rise and fall times of the signals as well as additional load on the IMC. Maximum RAM chip size has just jumped to 24GB allowing 48GB with two x single rank and 7200MTs (G.Skill 7200 or even 8000+ if you have an Apex M/B). I'm running the 7200 on my Asus ROG Z790 Hero and just about to start playing with faster timings 🙂). Great video BTW!
Been doing this for the better part of 20 years and this information still fascinated me. There was good information in here that I dont recall ever learning even in school
50:10 Actually, Some components voltages may be too high, Asus massage is more of an Asus Smash! If you are having trouble with 14th and XMP over 5800 try setting System Agent Voltage to 1.2 STATIC, it will probably save you.
I wish reviewers would do their first tests of CPUs while running memory at JEDEC. If that is the speed they guarantee, that is how they should be evaluated. If the CPU manufacturer thinks its "sweet spot" is 6000MT/s then they should validate the CPUs for that speed, especially if they say running XMP/ EXPO will void the warranty.
It's very simple, if the advertised speed isn't the JEDEC speed, then achieving the speed with XMP does not void warranty. If they want to claim that, you can simply countersue them for fraudulent marketing and earn an easy case win. If the basis of your purchase is that XMP-enabled speed was what they advertised, then that's what is legally binding in court. However, if you use XMP to exceed the advertised speed rating on the product packaging/marketed description, then it will void warranty.
@@Real_MisterSir Lets take AMD. They seeded reviewers with EXPO 6000MT/s sticks, claiming its the sweet spot memory. However if you look at their webpage it specifically lists DDR5-5200 2x2R or 2x1R as the Max supported memory speed. If this is all they are willing to cover under warranty/guarantee as an achievable speed, that should be what the base review uses.
I thought it was the reviewers (both good and bad ones honestly) pointed out ages ago how finiky memeory was with the newer playforms, sonetimes not even being able to achieve what they ARE rated for given the chips themselves
JJ has been the best spokesperson for Asus for years, always learning something new from him. Even though he works for the company, he actually gives valuable standardised info for a variety of products and situations not just Asus.
Great Video. We always face issues with our DDR5 prebuilds with XMP profile and 4 Ram Dimm configurations (128GB). We use a combination of tools to test our prebuilds with 4 RAM DIMM configuration on XMP. The most effective one that can show the XMP issue is the Aida64 Stability Test. Sometimes we run AIDA 64 + Unigine Heaven for 20 to 30 minutes. Most Low-end Rams never get XMP performance, and we find a stable frequency by manually checking each frequency. Once again this is done for our prebuilds as stability is considered the most important aspect of our systems.
Over 20+ years of building and upgrading PC's I've learned a lot and every day still a school day. Thanks for the video. I'm using 2x32GB 3600 DDR4 CL18. When building (Jan 2020) my current daily (3950X in the X570 AORUS MASTER). I researched different combo's (via forums/videos/websites etc) of ram kits, mobo, CPU, GPU's and compared the QVL. Which led me to this set up, its not always as simple as 'plug and play'. When dealing different PC hardware, taking time can help but sometime trouble shooting take time. Even for the most simple fixes!
Ok, just found your video. I had XMP working on an i9-10900k, then did a bios update and i have never been able to get it to work since. So its been a couple years, im cautiously optimistic. Will update after watching.
In all my years, even with fairly aggressive overclocking the CPU is generally the last thing to go. The highest failure rates are your motherboard, GPU and PSU.
I dont do any production tasks and just stick to gaming but i do like this channel and the content made. This video 100% works for both. Definitely a great video.
Great topic and excellent Guest. Very well versed. I don't think it a beginner video, more intemediate->enthusiasts/professionals. I was worried about the length, but he went systematically through explanation s. I learnt and added knowledge/understanding. Peace from South Africa 🇿🇦
I express my gratitude for an excellent tutorial. Initially, I acquired a Corsair DDR4-3600 64GB module and promptly observed that it failed to deliver the expected speed, resulting in the sluggish performance of applications and frequent crashes. Subsequently, I made an exchange for a DDR4-3200 64GB module. Upon attending an Asus BIOS class 101, I was able to optimize the settings, achieving the desired performance level.
Thats a ton lot of Info about NewGen RAM! I am a Average type that had a great hold of understanding about Computers but not a generally Overclocking type so this helped alot! Especially for those who understand more about how RAM and overclocking RAM works without the risk of damaging their investments blindingly. Thank you soo much to both of you keep up the good work and you have earned a subscriber! God Bless Sir!
My ram made my board post to safe mode every time I enabled XMP 3200 and default timings. Turns out the DDR4 sticks I bought from amazon is rated at 2133 and you can tell they just stamped the 3200 sticker on the box lid. Read carefully what they say in the description and also reviews with 1 or 2 stars. My advice is if you want a certain speed in ram always buy somewhat higher speed, in my case I want to hit 3200 therefore I will have to buy 3600 sticks or above.
The 4x DDR5 RAM problem of the Asus Prime Z690-A was solved with Bios update 2305. Have all my G Skill Tridenz Z5 5600Mhz installed & tested with MemTest86 V10.2 free (USB). Before it was not possible for me 4x DDR 5 with 5600Mhz stable to run. am glad that it now runs. Great video THANKS
Excellent and very informative video! It's too bad that ASUS doesn't have employees of the caliber of J.J. working in their customer support department.
Thank you so much for this video, I have built a 4K 10 bit editing machine this weekend. And struggled with this very issue- watched this and fixed that problem!
Great interview video, all the info JJ shown helps a lot. My setup is frustrating. i9-13900K with Asus Prime A Wifi Z790 MB and Corsair two sets of 64GB Kit 6000Mhz CL40 (2x32GB Sticks) for 128GB filling up all the DIMM slots. Only 2 DIMMs in A2/B2 slots and XMP enabled and the CPU overheats on POST. I think the best I seen 2 sticks go on self adjustment during POST is 4800 Mhz and I don't think within Windows it was that great working. 4 sticks has been hit and miss to even get into windows but at 2nd last POST they trained to 3600Mhz and when the computer would go to sleep would not wake up properly like the USBs in the back I/O panel were not active or something. Keyboard wireless to the Dongle was not connected looking. So on next BIOS entry i have the 4 sticks setup at 3000Mhz just changing that DRAM Frequency Drop down box for the Memory Divider and not changing anything else.
I'm upgradiing to a new PC with DDR5, but I would like to be able to use either 128GB or 192GB, but I am worried about the stablilty issues. I'd like to know more about adding only x2 48GB ram sticks for a total of 96GB.
The ROG certified memory profile works great on my Team Group Dark ROG 16GB DDR4-3000 (x2 8GB single rank). I bought this kit because of Toms Hardware review saying each stick was dual ranked. Either they were mistaken or IC's were drastically changed mid manufacture.
Phew. That was a lot to take in. I don't care about overclocking or gaming. I just need my workstation to run smoothly with the least set of problems. Please somenone just tell me what RAM/CPU/MOBO/GPU combination I have to buy so I can concentrate on my work 😫 I had decided on a ProArt Z790, after watching this, not so sure...
A really informative clip for newbies, but i did not hear any discussion about the real problem with ram and specs in general nowdays, manufacurers sell and advertise unrealistic speeds take for example base am5 specs which is 3600mt(mhz) on 4sticks, but both ram manufacturers and motherboard manufacturers advertise 7000mt or more, also all tests are done at those advertised speeds, what we end up is parts sold for advertised overclock speeds that they'll never reach
This has to be the best video I have seen picking regarding all of these questions surrounding DDR5. Excellent selection of questions and as always JJ knows his stuff.
22:00 lol that is me, wanting to go with 4x8GB config which is only 32GB instead of 64 or even 128. but its more than enough for my use cases; A- 1080p gaming B- 1080p 60Hz video editing C- 1080p game recording/streaming
This should be taught in elementary schools. I'm an old guy involved in custom PCs and what I've learned is that there are so many variables involved in a custom system that it's a miracle that it actually works in most cases. That is the reason why I appreciate Windows in the Linux vs Win debate.
Absolutely agree on the RAM massaging. I currently run a 64GB kit of Mushkin rated at 3600 MT/s CL16. It would downright refuse posting on my system with XMP enabled. However, when I started dialling it in manually I would inch closer and closer to stable 4000 MT/s CL 18 with super tight tertiary timings and even voltage below XMP. Going through that and learning the ins and outs of memory tuning was a cool and ultimately rewarding experience.
Such a high value interview! Massive amount of useful information and very pleasant to watch. GJ! Im running 2x32GB DDR5 6600 on an Asus ROG Strix Z790-H, intel i13700-k , BIOS v.1202 without issues so far.
I don't understand the statement 2 sticks of 32GB is better than 4 sticks of 16GB. The QVL listing for my Gigabyte Z790 Motherboard lists (i5-13600K): 1R8 sticks of 16GB from 7200 down to 6000. 2R8 sticks of 32GB from 6000 down to 3200. For 7200, you can only get it with 4 sticks of 1R8.
😂I.C. Integrated circuit A term we use in the 80’s..how i miss building my first FM radio and 50w amplifier during my high school electronics elective days..soldering each parts, reading resistor color, trouble shooting transistors, etching and building your own PCB’s,micro drilling each holes for electronic components and soldering each piece in the board..reading and mastering schematic diagram, my high school fun times🙂..
Make sure to check your motherboard's QVL list for the DDR5 ram you're wanting to install before you buy! I spent five hours trying to get Corsair Dominator 64GB (4x16) 7200mhz CL34 running on the ASUS Z790 Hero on XMP I & II. It would never post, even changing frequency and voltage. I decided to look up the QVL ram list for my motherboard with the ram brand I purchased, sure enough, it says right there, will only work using 32gb (2x16) not 64GB. I then consulted my manual for proper slots to use (2 and 4) and it fired right up without a single issue in XMP II. Also, I did update to the latest bios which provided better DDR5 support.
Do you think manufactures dont know what they are doing? Do you think they didn't know all these issues before launching DDR5? of course they do. Thing is as they work on the issues they release rams sticks because people will buy regardless. Is all about money. Always been. Always will be.
Corsair sells 4 dimm ddr5 kits I bought one like 2 weeks ago around the time the video dropped 4x16 6600mhz 32-39-39-76 corsair vengeance they have 4 dimm dominators too
In simpler terms, the "faster" and more densely populated (dual side vs single side, 16GB vs 8GB) the RAM sticks are, the less likely the kit will boot and be stable at XMP (DOCP, Expo). With one stick per channel, the OC profile will usually work even for a kit that's not on the motherboards QVL. With two per channel, it's a crap shoot. This is true for Intel and AMD. Probably the most important factor is the random quality of the IMC. My original R7 1700 would not run a particular 2x8GB 3200 at XMP-1, but I could turn off XMP and let it run at the default 2133 or manually clock it to 2667 and it was fine. At the same time, I had an R5 1500X with a magical IMC. It would run that same kit on the same motherboard at 3200 (XMP-1) without issue.
Enjoy this a lot. I remember when I got my Asus X99 Deluxe board back in 2015. It has 8 dimm slots and I have it fully populated but only 64gb total because back then 8GB was the largest dimm I could get, so I got 2x 4 dimm kits. It still runs great to this day running a 5960x.
Exact same configuration. I have 3 X99 boards, all ASUS. Originally had FlareX ( 8 x 8G ) on the Rampage V Edition 10 / 6900k, always worked great. Swapped in G.Skills Trident RGB ( 8 x 8G ) when I installed the Flare X onto a Aorus X399 TR4 Board with a 1950X. All kits I use are 3200mhz . Seems after the Trident Z was installed, little things would freeze ( like the mouse ) What faults can occur when it's a memory problem ? Can I manually reduce the Ram speed to 3000mhz to see if that helps or increase the voltage?
I have big complaints about Asus, they don't update their QVL lists, especially from older platforms like AM4, I have a new TUF board, and the 2x32Gb Corsair DIMMs they list, is almost a year obsolete. How the hell can you work with QVL lists that are not updated? Their service department also cannot answer my questions. So I have to find out myself if a stick works or not, that is a 200€ gamble.
My problem with 3200mhz ram was, after flashing bios, my XMP didn't work. Got crashes ect. The simple Solution: increasing the voltage from 1.35v to 1.36 solved the Issue Remember, if you go with XMP, give a little bit more voltage in 0.1v steps, till it runns stable. That's all.
XMP works fine on my Gigabyte MB with G Skill DDR5 6000. No problems. Just started OC the different components. Got my GPU done today.. People were complaining about the ram I have not running XMP and the speed it was designed for. I think that is a MB problem. G skill uses Samsung chips so it should always work well.
Good info, but a little bit Asus marketing skewed. But what is the real problem of getting faster DDR5 to work? Why isnt getting the right (slightly higher) VCC to the (individual) modules discussed? This does solve the issue with the memory controller in 13th and probably 14th gen Intel CPU. Pleas comment on this and maybe get a video out. Would be really interesting!
Memory needs to be translated to light rays rather than electricity for better and more accurate transportation as well as heat reducfion.. By translating the electric pulses to a light pulse run over fibre optics, less will be lost over transmission as well as accuracy will increase and memory speeds could be run harder with a more agressive overclock too.
Most people don't know that certain voltages in the UEFI/BIOS need to be increased when you enable XMP/XPO in for memory to be stable since it is actually overclocking.
This has to be the most insightful and informative Video I've seen on youtube in a good while. Thank you for bringing JJ on! I wish you had asked JJ a couple of question that came to mind during his talk, but I'm sure it was more that enough for you get answer for the questions you had written down. Again, excellent work. BTW do you have a patreon or something?😁
On that last part, where he said that certain applications can perform better on certain RAM speeds and timings, imagine having the option to set the corresponding RAM profile for the specific application that you are running to increase performance. That would first of all necessitate CPU manufacturers to not void their warranty for using an overclocked profile with their IMC. The application should obviously support that kind of functionality. The MB manufacturers would tag along, updating their UEFI correspondingly and RAM manufacturers would also optimize their products if need be.
My z790 Apex is a beast I daily 8000mhz stable. I was able to get 7800mhz XMP to work out the box. It wouldn't work on the Z790 Hero or Z790 Master even though its advertised. I have a 13900KS so it's binned plus I have a good MC so it should work as advertised on those boards.
Great informative video. I tried half a dozen RAM kits with my 7700x with Asus B650-A Gaming mainboard and DDR5 6000 CL 30, 32, 36, 40 kits and all failed at 6000mhz. Apparently the CPU memory controller can't run it stable. I managed to run it stable with 5600 MHz with at least the faster expo timings. I hope a future CPU replacement will run it stable at 6000.
Thank you for this informative video! I don't want to jinx myself, but I think I fixed my issues from this video. Memtest errors in first 10 minutes and OCCT threw 600 error in 3 minutes. Changed RAM slots (as in changing places, still using A2&B2). And turned on XMPII instead of XMP I. Memtest for 9 hours and no error. Looks like XMP I with Asus timings messed with my system. Games were BSODing etc. Asus Z790 PROART WIFI and Corair Vengeance 6400Mhz CL32. P.S. The AI OC uses XMP I.
Fantastic and very informative. Why do I want to buy a new system and run it at stock speed? Yet, as soon as I build it, I will probably chose to apply XMP or EXPO! For DaVinci Resolve, would there be that much difference ?
I am an old timer that had to learn this the hard way. My b760m board advertised 7200mhz memory support via xmp 3.0. Unfortunately the frequency supported changes depending on how many sticks you are using. So my 4 sticks became 4800mhz. System would take forever to post because it would fail at each startup and the ram would then default to 3200mhz and finally post.
Step 1 for AM5 used to be NOT to buy the Asus boards which were very picky and slow with memory training. There's a very recent BIOS which apparently improves the state with EXPO. I've seen overclockers complaining about the unpredictabe failure modes of the Intel memory controller, where you think it'll work but it falls over in certain applications.
Just an update for people who may read this in the future. Asus didn't have really working BIOS updates until about late August 2023. It took around a year for them to fix 99% of the BIOS issues (cpu voltage issues, ram issues etc). I have a TUF Gaming X670E Plus and some non QVL ram (generic GSkill trident z5 6000mhz ram) that works as long as I set the ram voltage manually. The rest of the XMP settings work fine. My pc has been stable since version 1654 BIOS. I'm not upgrading to a new bios any time soon as the newer update only seems to support new cpu releases.
@@RobBCactive No problem. I kept having random system reboots and stability issues and sometimes usb issues. They fixed the usb issues quickly but the ram issues took forever (like I said above August of 2023). I used to think that gigabyte where a bit meh for their medium level boards and ok on the low end boards and good on the high end boards. I was thinking of getting a Gigabyte board. I regret buying this Asus board. I only bought it because of the location I am I don't have a huge choice.
@@skilletpan5674 I had a Gigabyte x570 board on discount when B550 was newly out and been very pleased with it. I saw the reviews saying Gigabyte was solid, with ASrock reformed, so it just shows brand loyalty shouldn't replace specific product research.
Thanks for the video Fixed my XMP isssue. The comment on A2/B2 should be used. I am sure a dumb mistake, but I was in A1/B1 changed and now running find with XMP dram 6000
honestly people need to remember that just because 192GB DDR5-8800 CL28 is technically a combination of all the best specs, it isn't possible on an actual PC. You trade MT/s for Latency, and also quantity for both. That is why people don't buy the most expensive RAM, they buy the best middleground as that will be what gets them the most performance. In this case, 2x16GB for gaming and 2x32GB for productivity with DDR5-6000 CL30 is by far the best way to go.
As per Intel's website - 12400f supports DDR5 ram up to 4800MHz but Asus B760M-A AX supports OC ram up to 7200Mhz and normally supports up to 5600Mhz. My question is, if I run a dual channel ram, 2 sticks of 16GB with 5600Mhz. How will the CPU support it, will it lose bandwidth, will there be any bottlenecks??
I've had a nightmare trying to get 64gb of non-QVL RAM (Corsair Vengeance 5600 CL 40) to remain stable on my Proart Z790 - so, I've just swapped it for some QVL Kingston Fury Beast (with the same specs) and now I have the 'XMP Tweaked' option. If I can manage a week without a BSOD I'll report back and let you know - but so far so good. :)
OMG psychic. Mine doesn't work on 12th gen, will watch but XMP off it works. 12700KF and 12900KF both. I ended up throwing money at the problem which probably wasn't the smartest but w/e have 2 working rigs now.
Last month I spent about 2 days figuring this out on my newly built PC. I had random black screens and dead PC during gaming especially. While browsing solutions online, I remember watching one of your previous videos that actually talked about the compatability issue of XMP and 4 sticks DDR5 as well. That inspired me.

After setting to XMP2, all problems were gone and my PC never worked this smoothly before. Your video is EXACTLY the tour I had been through. I really hoped this life saver had come a bit earlier. Great review!
This is me right now. I'm on day 5.
XMP is intel gigante
@@NearMedia Yes sir this is the latest version by now. At the time I checked that out, 0904 wasn't available yet. Btw, 0816 works perfectly and I am not bothered to try 0904 for potentially new trash to deal with

4xDDR5 lowers the supported speeds.

I read the Gigabyite board notes and they were talking about their memory configuration avoiding drawbacks of daisy chaining. There's plenty of small server boards with ECC on the AMD side aimed at the small server market.
I just want to say thank you for this video! The information I attained from it is monumental when it comes to understanding how to approach RAM when building an enthusiast PC and overclocking as a whole and all of the specifics that need to be considered when choosing between speed, capacity and 2 or 4 sticks.
I fully agree, this video should be pinned and shared. The presentation and the educational value needs to be shared.
This is on of the most interesting and informative videos on UA-cam. I can only imagine how difficult it was to make. Thank you!
This channel is top tier. Deserves way more subs / recognition.
so is this comment!
Bot comment.
Good bot then
first of all, i was a bit scared away from a 1h41min video, but it was one of the best times spend to understand a lot of topics about memory better, than ever before. This will scale through many builds in the future!!!!
The ultimate guide indeed. This video is pure gold, countering all the misinformation and explaining clearly why 4 -v- 2 XMP stick configuratons may not give the expected results. Thank you!
finished the build for my wife yesterday:
13900K on a MSI Z790 Carbon Wifi with 4x 16GB Corsair (CMT32GX5M2X6200C36, 6200MHz CL36, Hynix M) running absolutly rock solid in XMP @ 6200 with latest BIOS (7D89v15).
Just turned on XMP1, expected a boot loop, but it simply worked with all stress tests. Fingers crossed. Very happy.
lock the p-cores on that 13900k asap.
I've been researching about technical difficulties with 4 sticks of DDR5. This by far provides so much information. thank you for this video.
I remember JJ from waaaaay back, and it's always good to hear him share his knowledge. Fantastic discussion - thank you!
I finally figured out how to use 4 sticks of DDR5 on a Z790 Dark Hero. This video shows you how, but it doesn't understand what it shows you. I had the same problem going from 64gb of 6400 ram (2 sticks) to 128gb of 6400 ram (4 sticks). I began only being able to run it with optimized defaults after returning my original purchase of the extra two sticks and exchanging it. The return wasn't necessary and didn't work. After a couple of UA-cam videos that said that I can just reset the BIOS, I could run it at the optimized default settings. It ran, but at 4200. After watching this video, I was inadvertently shown where you can see the true speed of the ram and that the speed printed on the box is the overclock speed. On the EZ Mode settings above the X.M.P., it will tell you the speed of the ram the motherboard sees. Do not change the setting in EZ Mode, leave it disabled. Go back to Advanced Mode and leave everything to Auto. Drop down to Memory controller and change the frequency to 4800. Don't touch anything else. Save settings and reboot. It will reboot with the new settings. Yes, it runs at 6400 when I use 2 sticks. This does not apply with 4 sticks. I know that at 4200 my system is very stable. It is a bit faster at 4800, but I need to use it for a while to test how stable it actually is. I do know that I couldn't get it to boot when I used a higher speed, and the video didn't turn on. On the Dark Hero, I have to remove the CMOS battery to reset the BIOS. This is a pain. Anyway, I am up now. If I experience anymore glitches, I know I can reset the BIOS to its default settings and run without issues. I bought the extra ram because 64gb wasn't enough ram and I crashed when I had too many tabs open in Microsoft Edge. With 128gb of ram, or 4 sticks, I am more stable and don't crash. Anyway, I hope this helps.
I was just about to buy parts for my first build - this was the perfect course on what to look for and more importantly why! Thanks for doing it. I learned a lot and hopefully saved serious time and money!
Man! What a greatly informative, interesting, and helpful video!! This clarified a bunch of questions I’ve had for years. Thank you for such a thoughtful interview (with perfect questions) with just the right person.
wow... I am building a PC after many many years and had so many questions regarding RAM and XMP. Your video answered almost every single question that had come to my mind and then some. I could not hit the Subscribe button fast enough. Bless you for such a detailed and informative video
Any video with JJ is gonna be a banger, definite knowledge being dropped on ya. Third of the way through the video and I'm hooked. Thanks guys for the collab.
There should be a notice on the box!
I bought two 2x16GB Corsair Vengeance RGB 6000 kits and could not get a proper overclock no matter what I did. 4800 is just too too slow for me! Luckily I was able to return them and I bought a single 2x32GB G.Skill Trident Z5 RGB 6400 kit instead.
Kingpin did an interview explaining these things not long ago. I can't find it, otherwise I would link it. He said the same thing a lot quicker and clearer than this guy. Basically, Kingpin was saying his preference in motherboards for overlocking stability was for only 2 DIMM slots. The more slots you add, the more noise potential you introduce. The more noise, the slower the speed potential. Same with DIMMS - single sided DIMMs (or single-rank as they are also called) are capable of higher speeds than dual-rank DIMMS. (double sided). The fewer IC's on a DIMM the more stable it could/should be.
I think that 'rank' can better be explained by considering the extra capacitance added to the address and data lines if the sticks are double sided (current 32gb per stick!). This extra capacitance slows down the rise and fall times of the signals as well as additional load on the IMC. Maximum RAM chip size has just jumped to 24GB allowing 48GB with two x single rank and 7200MTs (G.Skill 7200 or even 8000+ if you have an Apex M/B). I'm running the 7200 on my Asus ROG Z790 Hero and just about to start playing with faster timings 🙂). Great video BTW!
Been doing this for the better part of 20 years and this information still fascinated me. There was good information in here that I dont recall ever learning even in school
50:10 Actually, Some components voltages may be too high, Asus massage is more of an Asus Smash! If you are having trouble with 14th and XMP over 5800 try setting System Agent Voltage to 1.2 STATIC, it will probably save you.
I wish reviewers would do their first tests of CPUs while running memory at JEDEC. If that is the speed they guarantee, that is how they should be evaluated. If the CPU manufacturer thinks its "sweet spot" is 6000MT/s then they should validate the CPUs for that speed, especially if they say running XMP/ EXPO will void the warranty.
It's very simple, if the advertised speed isn't the JEDEC speed, then achieving the speed with XMP does not void warranty. If they want to claim that, you can simply countersue them for fraudulent marketing and earn an easy case win. If the basis of your purchase is that XMP-enabled speed was what they advertised, then that's what is legally binding in court.
However, if you use XMP to exceed the advertised speed rating on the product packaging/marketed description, then it will void warranty.
@@Real_MisterSir Lets take AMD. They seeded reviewers with EXPO 6000MT/s sticks, claiming its the sweet spot memory. However if you look at their webpage it specifically lists DDR5-5200 2x2R or 2x1R as the Max supported memory speed. If this is all they are willing to cover under warranty/guarantee as an achievable speed, that should be what the base review uses.
I thought it was the reviewers (both good and bad ones honestly) pointed out ages ago how finiky memeory was with the newer playforms, sonetimes not even being able to achieve what they ARE rated for given the chips themselves
JJ has been the best spokesperson for Asus for years, always learning something new from him. Even though he works for the company, he actually gives valuable standardised info for a variety of products and situations not just Asus.
Great Video. We always face issues with our DDR5 prebuilds with XMP profile and 4 Ram Dimm configurations (128GB). We use a combination of tools to test our prebuilds with 4 RAM DIMM configuration on XMP. The most effective one that can show the XMP issue is the Aida64 Stability Test. Sometimes we run AIDA 64 + Unigine Heaven for 20 to 30 minutes. Most Low-end Rams never get XMP performance, and we find a stable frequency by manually checking each frequency. Once again this is done for our prebuilds as stability is considered the most important aspect of our systems.
Over 20+ years of building and upgrading PC's I've learned a lot and every day still a school day. Thanks for the video. I'm using 2x32GB 3600 DDR4 CL18. When building (Jan 2020) my current daily (3950X in the X570 AORUS MASTER). I researched different combo's (via forums/videos/websites etc) of ram kits, mobo, CPU, GPU's and compared the QVL. Which led me to this set up, its not always as simple as 'plug and play'. When dealing different PC hardware, taking time can help but sometime trouble shooting take time. Even for the most simple fixes!
Ok, just found your video. I had XMP working on an i9-10900k, then did a bios update and i have never been able to get it to work since. So its been a couple years, im cautiously optimistic. Will update after watching.
In all my years, even with fairly aggressive overclocking the CPU is generally the last thing to go. The highest failure rates are your motherboard, GPU and PSU.
They seem to be the most expensive right now. Good business for the manufactures.
@@Loppy2u .. Yeah engineering failure by design is pretty evil.

I dont do any production tasks and just stick to gaming but i do like this channel and the content made. This video 100% works for both. Definitely a great video.
Great topic and excellent Guest. Very well versed. I don't think it a beginner video, more intemediate->enthusiasts/professionals. I was worried about the length, but he went systematically through explanation s. I learnt and added knowledge/understanding. Peace from South Africa 🇿🇦
I express my gratitude for an excellent tutorial. Initially, I acquired a Corsair DDR4-3600 64GB module and promptly observed that it failed to deliver the expected speed, resulting in the sluggish performance of applications and frequent crashes. Subsequently, I made an exchange for a DDR4-3200 64GB module. Upon attending an Asus BIOS class 101, I was able to optimize the settings, achieving the desired performance level.
Thats a ton lot of Info about NewGen RAM! I am a Average type that had a great hold of understanding about Computers but not a generally Overclocking type so this helped alot! Especially for those who understand more about how RAM and overclocking RAM works without the risk of damaging their investments blindingly. Thank you soo much to both of you keep up the good work and you have earned a subscriber! God Bless Sir!
My ram made my board post to safe mode every time I enabled XMP 3200 and default timings. Turns out the DDR4 sticks I bought from amazon is rated at 2133 and you can tell they just stamped the 3200 sticker on the box lid. Read carefully what they say in the description and also reviews with 1 or 2 stars. My advice is if you want a certain speed in ram always buy somewhat higher speed, in my case I want to hit 3200 therefore I will have to buy 3600 sticks or above.
The 4x DDR5 RAM problem of the Asus Prime Z690-A was solved with Bios update 2305. Have all my G Skill Tridenz Z5 5600Mhz installed & tested with MemTest86 V10.2 free (USB). Before it was not possible for me 4x DDR 5 with 5600Mhz stable to run. am glad that it now runs. Great video THANKS
Excellent and very informative video! It's too bad that ASUS doesn't have employees of the caliber of J.J. working in their customer support department.
This guy is actually very knowledgeable. Good content.
Thank you so much for this video, I have built a 4K 10 bit editing machine this weekend. And struggled with this very issue- watched this and fixed that problem!
Regardless of Asus's issues, Juan Guerrero is a brilliant contributor. He really knows his onions and explains complex tech very well.
Great interview video, all the info JJ shown helps a lot. My setup is frustrating. i9-13900K with Asus Prime A Wifi Z790 MB and Corsair two sets of 64GB Kit 6000Mhz CL40 (2x32GB Sticks) for 128GB filling up all the DIMM slots. Only 2 DIMMs in A2/B2 slots and XMP enabled and the CPU overheats on POST. I think the best I seen 2 sticks go on self adjustment during POST is 4800 Mhz and I don't think within Windows it was that great working. 4 sticks has been hit and miss to even get into windows but at 2nd last POST they trained to 3600Mhz and when the computer would go to sleep would not wake up properly like the USBs in the back I/O panel were not active or something. Keyboard wireless to the Dongle was not connected looking. So on next BIOS entry i have the 4 sticks setup at 3000Mhz just changing that DRAM Frequency Drop down box for the Memory Divider and not changing anything else.
I'm upgradiing to a new PC with DDR5, but I would like to be able to use either 128GB or 192GB, but I am worried about the stablilty issues. I'd like to know more about adding only x2 48GB ram sticks for a total of 96GB.
The ROG certified memory profile works great on my Team Group Dark ROG 16GB DDR4-3000 (x2 8GB single rank). I bought this kit because of Toms Hardware review saying each stick was dual ranked. Either they were mistaken or IC's were drastically changed mid manufacture.
Great content! I had a bit of trouble getting 4 sticks to post at XMP speeds, and now I understand why. I had to up the voltage to 1.45v.
I was waiting for that Topology talk mmmmm MMMMMMMMMMM!
Phew. That was a lot to take in.
I don't care about overclocking or gaming. I just need my workstation to run smoothly with the least set of problems. Please somenone just tell me what RAM/CPU/MOBO/GPU combination I have to buy so I can concentrate on my work 😫 I had decided on a ProArt Z790, after watching this, not so sure...
A really informative clip for newbies, but i did not hear any discussion about the real problem with ram and specs in general nowdays, manufacurers sell and advertise unrealistic speeds take for example base am5 specs which is 3600mt(mhz) on 4sticks, but both ram manufacturers and motherboard manufacturers advertise 7000mt or more, also all tests are done at those advertised speeds, what we end up is parts sold for advertised overclock speeds that they'll never reach
JJ! Man he's been around for a minute :D glad to see him :D
This has to be the best video I have seen picking regarding all of these questions surrounding DDR5. Excellent selection of questions and as always JJ knows his stuff.
22:00 lol that is me, wanting to go with 4x8GB config which is only 32GB instead of 64 or even 128. but its more than enough for my use cases; A- 1080p gaming B- 1080p 60Hz video editing C- 1080p game recording/streaming
This should be taught in elementary schools.
I'm an old guy involved in custom PCs and what I've learned is that there are so many variables involved in a custom system that it's a miracle that it actually works in most cases.
That is the reason why I appreciate Windows in the Linux vs Win debate.
Thank you guys. Detailed questions and more detailed answers. Continue again. I follow you from the Middle East
Absolutely agree on the RAM massaging. I currently run a 64GB kit of Mushkin rated at 3600 MT/s CL16. It would downright refuse posting on my system with XMP enabled. However, when I started dialling it in manually I would inch closer and closer to stable 4000 MT/s CL 18 with super tight tertiary timings and even voltage below XMP. Going through that and learning the ins and outs of memory tuning was a cool and ultimately rewarding experience.
Well you can get & tune fast memory with x3D then discover the lower rated untuned cheapest has the same application performance. 😮😮
This helps alot, and because of this i subscribed. I mostly game but this channel still has alot of good info
Such a high value interview! Massive amount of useful information and very pleasant to watch. GJ!
Im running 2x32GB DDR5 6600 on an Asus ROG Strix Z790-H, intel i13700-k , BIOS v.1202 without issues so far.
I don't understand the statement 2 sticks of 32GB is better than 4 sticks of 16GB.
The QVL listing for my Gigabyte Z790 Motherboard lists (i5-13600K):
1R8 sticks of 16GB from 7200 down to 6000.
2R8 sticks of 32GB from 6000 down to 3200.
For 7200, you can only get it with 4 sticks of 1R8.

i'm really starting to love this channel. just found it the other day. this is good stuff! everyone should subscribe
Welcome aboard!
Thanks for the video! This memory thing is so frustrating..
This is such a comprehensive and helpful video for understanding XMP. Thanks so much for creating this!
Make sure to check your motherboard's QVL list for the DDR5 ram you're wanting to install before you buy! I spent five hours trying to get Corsair Dominator 64GB (4x16) 7200mhz CL34 running on the ASUS Z790 Hero on XMP I & II. It would never post, even changing frequency and voltage. I decided to look up the QVL ram list for my motherboard with the ram brand I purchased, sure enough, it says right there, will only work using 32gb (2x16) not 64GB. I then consulted my manual for proper slots to use (2 and 4) and it fired right up without a single issue in XMP II. Also, I did update to the latest bios which provided better DDR5 support.
Do you think manufactures dont know what they are doing? Do you think they didn't know all these issues before launching DDR5? of course they do. Thing is as they work on the issues they release rams sticks because people will buy regardless. Is all about money. Always been. Always will be.
This is frikkin awesome information!!!
Learnt so much
Corsair sells 4 dimm ddr5 kits I bought one like 2 weeks ago around the time the video dropped 4x16 6600mhz 32-39-39-76 corsair vengeance they have 4 dimm dominators too
In simpler terms, the "faster" and more densely populated (dual side vs single side, 16GB vs 8GB) the RAM sticks are, the less likely the kit will boot and be stable at XMP (DOCP, Expo). With one stick per channel, the OC profile will usually work even for a kit that's not on the motherboards QVL. With two per channel, it's a crap shoot. This is true for Intel and AMD. Probably the most important factor is the random quality of the IMC. My original R7 1700 would not run a particular 2x8GB 3200 at XMP-1, but I could turn off XMP and let it run at the default 2133 or manually clock it to 2667 and it was fine. At the same time, I had an R5 1500X with a magical IMC. It would run that same kit on the same motherboard at 3200 (XMP-1) without issue.
Enjoy this a lot. I remember when I got my Asus X99 Deluxe board back in 2015. It has 8 dimm slots and I have it fully populated but only 64gb total because back then 8GB was the largest dimm I could get, so I got 2x 4 dimm kits. It still runs great to this day running a 5960x.
Exact same configuration. I have 3 X99 boards, all ASUS. Originally had FlareX ( 8 x 8G ) on the Rampage V Edition 10 / 6900k, always worked great. Swapped in G.Skills Trident RGB ( 8 x 8G ) when I installed the Flare X onto a Aorus X399 TR4 Board with a 1950X. All kits I use are 3200mhz . Seems after the Trident Z was installed, little things would freeze ( like the mouse ) What faults can occur when it's a memory problem ? Can I manually reduce the Ram speed to 3000mhz to see if that helps or increase the voltage?
Just came across this video and your channel, instant sub! This video is just epic! Can't wait to watch your other content, keep up the great work!
I have big complaints about Asus, they don't update their QVL lists, especially from older platforms like AM4, I have a new TUF board, and the 2x32Gb Corsair DIMMs they list, is almost a year obsolete. How the hell can you work with QVL lists that are not updated? Their service department also cannot answer my questions. So I have to find out myself if a stick works or not, that is a 200€ gamble.
What AIO is that on the background system? That screen is massive!
My problem with 3200mhz ram was, after flashing bios, my XMP didn't work. Got crashes ect.
The simple Solution: increasing the voltage from 1.35v to 1.36 solved the Issue
Remember, if you go with XMP, give a little bit more voltage in 0.1v steps, till it runns stable. That's all.
XMP works fine on my Gigabyte MB with G Skill DDR5 6000. No problems. Just started OC the different components. Got my GPU done today.. People were complaining about the ram I have not running XMP and the speed it was designed for. I think that is a MB problem. G skill uses Samsung chips so it should always work well.
Good info, but a little bit Asus marketing skewed. But what is the real problem of getting faster DDR5 to work? Why isnt getting the right (slightly higher) VCC to the (individual) modules discussed? This does solve the issue with the memory controller in 13th and probably 14th gen Intel CPU.
Pleas comment on this and maybe get a video out. Would be really interesting!
This is a great video! I wish I would’ve watched this before my most recent build.
The best damn video I've seen on the internet on RAM and XMP.
Holly Molly, that video is big but I need to watch it whole
Memory needs to be translated to light rays rather than electricity for better and more accurate transportation as well as heat reducfion..
By translating the electric pulses to a light pulse run over fibre optics, less will be lost over transmission as well as accuracy will increase and memory speeds could be run harder with a more agressive overclock too.
Most people don't know that certain voltages in the UEFI/BIOS need to be increased when you enable XMP/XPO in for memory to be stable since it is actually overclocking.
Excellent video! It really helped my understanding of DDR5 RAM.
Super fascinating to know every part has variances / performance limits.. great interview !!
Good morning this was very good explanation of the mem 😊
This has to be the most insightful and informative Video I've seen on youtube in a good while. Thank you for bringing JJ on!
I wish you had asked JJ a couple of question that came to mind during his talk, but I'm sure it was more that enough for you get answer for the questions you had written down. Again, excellent work.
BTW do you have a patreon or something?😁
Great Video! Thank you both and anyone else involved. Learned a lot!
Huge amount of valuable info on RAM. Many thanks!
On that last part, where he said that certain applications can perform better on certain RAM speeds and timings, imagine having the option to set the corresponding RAM profile for the specific application that you are running to increase performance.
That would first of all necessitate CPU manufacturers to not void their warranty for using an overclocked profile with their IMC. The application should obviously support that kind of functionality. The MB manufacturers would tag along, updating their UEFI correspondingly and RAM manufacturers would also optimize their products if need be.
Great video but what mobo is that on the table? Asus ROG...... please tell me.
Thanks
My z790 Apex is a beast I daily 8000mhz stable. I was able to get 7800mhz XMP to work out the box. It wouldn't work on the Z790 Hero or Z790 Master even though its advertised. I have a 13900KS so it's binned plus I have a good MC so it should work as advertised on those boards.
Cries in z70 Max Hero
Same here z790 tachyon and apex..8000 is a joke. 6000 ram is slower than ddr4 4000 so minimums is 7200. I find this video a joke
This is an awesome video. Send it to all your friends
Great informative video. I tried half a dozen RAM kits with my 7700x with Asus B650-A Gaming mainboard and DDR5 6000 CL 30, 32, 36, 40 kits and all failed at 6000mhz. Apparently the CPU memory controller can't run it stable. I managed to run it stable with 5600 MHz with at least the faster expo timings. I hope a future CPU replacement will run it stable at 6000.
Thank you for this informative video!
I don't want to jinx myself, but I think I fixed my issues from this video.
Memtest errors in first 10 minutes and OCCT threw 600 error in 3 minutes.
Changed RAM slots (as in changing places, still using A2&B2). And turned on XMPII instead of XMP I.
Memtest for 9 hours and no error.
Looks like XMP I with Asus timings messed with my system. Games were BSODing etc.
Asus Z790 PROART WIFI and Corair Vengeance 6400Mhz CL32.
P.S. The AI OC uses XMP I.
Fantastic and very informative.
Why do I want to buy a new system and run it at stock speed? Yet, as soon as I build it, I will probably chose to apply XMP or EXPO!
For DaVinci Resolve, would there be that much difference ?
Thank you!! This answered a dozen questions I had and several more that were important but I didn't even know to ask.
I am an old timer that had to learn this the hard way. My b760m board advertised 7200mhz memory support via xmp 3.0. Unfortunately the frequency supported changes depending on how many sticks you are using. So my 4 sticks became 4800mhz. System would take forever to post because it would fail at each startup and the ram would then default to 3200mhz and finally post.
Wow. This was more like a university level experience. Great video.
Awesome stuff, such a pleasure to learn from this guy.
Step 1 for AM5 used to be NOT to buy the Asus boards which were very picky and slow with memory training. There's a very recent BIOS which apparently improves the state with EXPO. I've seen overclockers complaining about the unpredictabe failure modes of the Intel memory controller, where you think it'll work but it falls over in certain applications.
Just an update for people who may read this in the future. Asus didn't have really working BIOS updates until about late August 2023. It took around a year for them to fix 99% of the BIOS issues (cpu voltage issues, ram issues etc).
I have a TUF Gaming X670E Plus and some non QVL ram (generic GSkill trident z5 6000mhz ram) that works as long as I set the ram voltage manually. The rest of the XMP settings work fine. My pc has been stable since version 1654 BIOS. I'm not upgrading to a new bios any time soon as the newer update only seems to support new cpu releases.
@@skilletpan5674 thanks for that info update! It's pretty sad, Asus used to be my goto mobo brand, but that was before they jacked their prices up.
@@RobBCactive No problem. I kept having random system reboots and stability issues and sometimes usb issues. They fixed the usb issues quickly but the ram issues took forever (like I said above August of 2023). I used to think that gigabyte where a bit meh for their medium level boards and ok on the low end boards and good on the high end boards. I was thinking of getting a Gigabyte board. I regret buying this Asus board. I only bought it because of the location I am I don't have a huge choice.
@@skilletpan5674 I had a Gigabyte x570 board on discount when B550 was newly out and been very pleased with it.
I saw the reviews saying Gigabyte was solid, with ASrock reformed, so it just shows brand loyalty shouldn't replace specific product research.
Nice one at 0:15, there is a FURY (FUw RYasons)! Great vid!
Great Video! I even sat through the entire video! Great information thank you and JJ from Asus too!
PC performance schooling that is not esoteric. I understood JJ's explanations to your well thought out questions.
I haven't had any problems with DDR4, even mixing up brands, XMP and non XMP and speeds.
Thanks for the video Fixed my XMP isssue. The comment on A2/B2 should be used. I am sure a dumb mistake, but I was in A1/B1 changed and now running find with XMP dram 6000
51:50 and otherwise, can a kit not from QVL list work perfectly?
honestly people need to remember that just because 192GB DDR5-8800 CL28 is technically a combination of all the best specs, it isn't possible on an actual PC. You trade MT/s for Latency, and also quantity for both. That is why people don't buy the most expensive RAM, they buy the best middleground as that will be what gets them the most performance. In this case, 2x16GB for gaming and 2x32GB for productivity with DDR5-6000 CL30 is by far the best way to go.
As per Intel's website - 12400f supports DDR5 ram up to 4800MHz but Asus B760M-A AX supports OC ram up to 7200Mhz and normally supports up to 5600Mhz.
My question is, if I run a dual channel ram, 2 sticks of 16GB with 5600Mhz. How will the CPU support it, will it lose bandwidth, will there be any bottlenecks??
I've had a nightmare trying to get 64gb of non-QVL RAM (Corsair Vengeance 5600 CL 40) to remain stable on my Proart Z790 - so, I've just swapped it for some QVL Kingston Fury Beast (with the same specs) and now I have the 'XMP Tweaked' option.
If I can manage a week without a BSOD I'll report back and let you know - but so far so good. :)
OMG psychic. Mine doesn't work on 12th gen, will watch but XMP off it works. 12700KF and 12900KF both. I ended up throwing money at the problem which probably wasn't the smartest but w/e have 2 working rigs now.
