Wow, @13:20 the correlation with X3D profile plus PBO with stock or PBO (only) is amazing. Seems like easy performance gain with more to come. That chip wants to fly. No wonder you had a great time with this chip.
@@CarnivoryHODL My Crosshair board has 3 X3D profiles that were added to the BIOS after the launch of the AM5 X3D chips. Be sure to check for recent new BIOS
@@ryanodneal7001 Where do you think I’d find it in the bios? I’m on gigabyte, not asus, so what were the x3d profile names and what menu were they on? Thanks so much!
I really like your way of explaining things and amazing that you share your OC:s with the world! The only thing i would personally prefer is that you made the OC on a non closed loop liquid. The majority of ppl doesnt have that good cooling so doing what you recommend with for example an AIO could destory the system.
Such a in depth video.....I am getting a 7800x3d with a msi x67e carbon wifi in the next week or so....hope I can get as close as possible to your results
Maybe you've covered this in another video, but can you explain your method for determining your per core curve optimizer offsets? (Or direct me to it) or is it exactly as it seems and is just a time consuming and tedious process if you truly want to have every core at the edge? I'm curious to know your process either way.
It very much is a tedious and time-consumption process. The specific tuning process depends a lot of the specific CPU, because I find that some CPUs are more sensitive to different types of workloads (SSE, AVX, etc). But my general process is pretty simple: Set negative all core curve optimizer, then check stability with Prime95 small ffts no avx for each core separately (affinity). I just check for 20sec because I'm only interested in whether it crashes immediately or not. Then, as long as all cores pass, further increase the negative curve optimizer in steps of 5. Then, when 1 core fails switch to per-core curve optimizer and back down on the one core that failed and keep going with the others. When you have a configuration that works for all cores, it's time to double check stability in various scenarios. I usually do: 1) Per-core SuperPI 32M, to check high-boost stability in light workloads 2) Prime95 small ffts all core non-avx, to check boost in non-avx heavy workload 3) Prime95 small ffts all core avx2, to check boost in avx heavy workload 4) Run all my benchmarks to ensure stability For 1, 2, and 3, you can easily spot which core is unstable and then just back down with Curve Optimizer for that core. For 4, it's more difficult, so I just back down 5 steps for all cores to build in margin.
@@SkatterBencher Thank you so much for taking the time to detail this out. I guess I need to reinstall prime95. It's been years since I used it last and I wasn't aware you could do per core testing. SuperPI will be a huge help too because my biggest issue always seems to be high boost light workload instability with my last few builds. Thanks again. You should consider making this into a video, I can almost guarantee there are a lot of people out there that would love to have this in your usual format as a visual walkthrough for getting the most out of their CO.
@@SkatterBencher Just started my 7800x3D build and I would like to say thanks for this. Got a question regarding 1/2/3 though, how exactly do we spot the failing cores? All cores pass with -30 for 5 mins each for non avx but when I start with avx2 with the same settings it crashes(bsod) immediately and I can't tell which core was doing it heh.
I noticed your cpu soc voltage is 1.35v, with the recent news of the burning chips and expo problems, the manufacturers are hard locking the new bios versions to 1.30v max, was wondering your thoughts on this. Many users are manually setting the soc to 1.25v to be on the safe side at least until more info is known. Thanks for the video.
I've been trying to follow the news about the burning up a little bit (including some of the in-depth pieces). Generally, I'm a bit annoyed with the coverage because there's still lots of speculation and jumping to conclusions. Also, I'm not a fan of calling people "lazy" without evidence. It implies intentional malfeasance. My opinion is that 100mV difference will never be the difference between "guaranteed burnout" and "absolute safety", unless there is a specific hardware design flaw causing that. Going by the physical damage, it's clear some thermal protection is failing. That could related to a dysfunctional physical sensor in the CPU or some edge-case SMU firmware bug, or something different. But what's it's not is +100mV :). I look at the BIOS voltage limitations as a way to show customers something's actively being done about it and to shift the conversation to "it's those darned overclockers again". You know ... it's not "in spec" but "out of spec" behavior. I'm not confident we'll ever know the true root cause of this issue. And, honestly, I don't really care that much about the root cause being known by the public. I'm just a bit worried that this will further detract AMD from actively investing resources to enable great overclocking experiences.
Great video, with tons of information. Recently built my first PC in over 20 years and my specific 7800X3D CPU can take a max negative curve optimization of -25 all core when running EXPO tweaked profile. -30 and greater seems to cause stability issues when benchmarking in AIDA64 Extreme.
Thank you for this incredibly useful information. Although I cannot find eCLK configurations on my MSI b650-P WIFI, this video inspired me to increase my base clock via the FCH option available to me. I performed a moderate increase of 102, which sped up the entire system just a touch. I used Ryzen Master to understand my best cores, and used HWINFO during gaming to infer the remaining cores capability. My CPUS cores in ordered of best to worst are 2,4,1,3,5,6,8,7 so I simply set a moderate curve optimizer of -5 and -0 for top 2 cores and +5 for the remaining cores. Very stable, no WHEAs, and increased boost clock to a bit over 5200. Thank you again!
since the x3D architecture is aimed at being a 'gaming' chip, would it not be best to have a config that allows 1 or 2 cores to boost high rather than an across-the-board medium uplift?
So the real question. Does it has FPS improvements or just 1% 0.1% lows on games ? thanks for the video, I just build my rig yesterday. 7800x 3d , 64gb 6400 CL32 on a x670e RS Asrock mainboard.
Sensacional, objetivo e direto... À simplicidade nas explicações atigiu o apce da magnitude. Irei fazer no meu sistema, pois imaginei que não seria possível em tal processador. Fico super grato pelo ensinamenteo.
Have you thought about delidding the CPU?? From other videos I've seen, at least for the non 3d variants, it seems to be more or less free performance, or free power/heat savings. Would be fun to see you maybe push this processor even more, or see how much lower temps/power draw you can get which is quite important for sff builds.
I'm very interested in doing this since mine runs on a fractal ridge case. The ihs seems to be too thick to allow height compatibility with coolers, so removing it already benefits heat transfer
@@Dodgerca With zen 4, even if you add + voltage to curve optimizer it will not go past the hard cutoff. Temps also will hard stop at the maximum temp. Unless you really go out of your way to disable default protections, it's going to be rather difficult to kill one. The thing that works best for zen 4 is PBO + curve optimizing, maybe eclock if you have it on your board as well, and with these it's very safe.
@@Jootn2kx I have a Gigabyte B650E Aorus Master. As long as the motherboard BIOS as async mode you should be good to go. Then just down to silicon loto at that point. i have tested out 7 AM5 CPU so far and only 1 has been able to run at 6400 Memory speed.
@@Jootn2kx Nice! I grabbed a 7800x3d this morning on newegg. Says it will be here tomorrow. I will test it out as well, still have 8 day return window at Microcenter on my 7900x3d.
I wish eclk was still effective on this cpu for multi core workloads, sadly not the case. Even if i copy your exact settings (theyre not fully stable for me) i dont get anywhere close your frequency, im getting 4620 effective in p95 avx disabled, whereas you were getting 4850. Would you know why exactly? Eclk is still good for single core tho Same motherboard A follow up video on this with a recent bios would be so cool, but it might be a lot of work, i understand
The fact he uses asus makez me roll my eyes, would be nice if he used boards that werent overpriced in his tutorials, asrock has boards that are just as good for much less
Ryzen Master has a Curve Optimizing feature that will give the most performant voltage curve per core. I recommend using it because it was very accurate versus my manual tuning would have saved a lot of hours of testing.
Ryzen Master on 7000 should only be used for viewing, pressing "Apply" garbles the BIOS nvram on some AM5 boards (all ASUS in my experience), and you wouldn't be able to boot until you clear CMOS.
It is not, still stuck as a halo feature. For example it's not on the MSI Carbon ($480) but i heard that it's on the Ace ($700). This Asus board also costs about that much.
Hey Skatter Bench, I delid my 7800x3d and confirmed it would post! I don’t plan to use Liquid Metal but PTM 7950. Do you think I could go up to the 1.2V limit with a voltage offset? I am hoping to get an all core OC above 5 ghz using pbo2 and bclk like you did here. Thanks for the detailed guide keep the content coming.
Great video. Helped me to understand what all the acronyms meant. My old 2600k was the last OC I have done. But it has been purring at 4.4ghz under an AIO for 10 years. It idles at lower temp than the 7800x3d which is also under an AIO. But seeing boost to 5150mhz using PBO2 curve at -30 and a 102mhz base clock. Ran p95 at up to 70c for 5 minutes. I am curious what I can undervolt to now to drop a few more degrees. I would like to know if I could OC just the boost. So it has a 5500mhz ceiling but idle and surfing the web only uses stock speeds for the most part.
I'm on a 5800x3d but plan on upgrading to a 7800x3d when the time is right- love all your videos you're a legend but I do have one question- does pbo on am4 introduce any sort of added system/input latency? I'm a competitve fps gamer and currently run my 5800x3d with SMT disabled no PBO etc. I guess in theory PBO/any overclock should actually lower input latency as it's effectively the same as having a higher IPC on a CPU? I spent years dealing with/learning about multi CCD core-to-core latency penalty w/ a 5950x before realizing that the slugish aim I was experencing in FPS games was actually the result of higher than usual DPC/system latency due to the fact the game was running on multiple physical + virtual cores and communicating across multiple CCDs. And i've recently started learning about processor IPC and how intel is generally better for gaming because of a higher IPC. What I can't wrap my head around is what is the 'definitive' way to determine which modern process- thanks in advance!
Newbie here, so from what I can take in, this is a rather hit and miss proceedure with the only monitoring feedback that its working is temperatures, but it could still render your system unstable or even damage your sockets because you are driving them beyond their specified power/current limits? So ultimately, you could be reducing the lifetime of your CPU and motherboard?
@@PREDATEURLT Yeah I don’t know about that one, EXPO/XMP on DDR5 is hot garbage so even if it’s *only* 10-20% cumulative you’ll more than notice the uplift in 1% and 0.1% lows.
@Triston Davis No. You don't notice a drastic difference on 0.1 or 1% lows. OC'ing CPUs and tightening timings on ram isn't as beneficial in games as it is for editing/production software. Gaming, you may gain 10fps after already having 110fps. You won't notice. Back when you used to have to solder CPU pins together to unlock them, you could go from 2.0GHz to 2.8GHz. You'd get a 40% uplift. Now people are all excited over 9 or 10% 😑 On my 4790K I went from 4.0GHz all core OC to 4.4GHz (10%) and gained 4fps at 1080p and 3fps at 1440p on AAA titles with a 1080 Ti. With CL7 1600MHz ram (later used 2,400MHz CL11).
Why did you choose Expo I vs Expo II? Btw, I just found your UA-cam channel. I had read your OC information but did not know you had a UA-cam channel. Visuals are always better than just words. Much appreciated.
I love your videos regarding undervolt and overclock! Amazing work! However I am stuck with one question I ask myself after looking at this video twice. For pure gaming purpose I assume you would go either OC Strat #1 (The easy way) OR OC Strat #3 which takes some more time to find the perfect negative curve I assume? Tyvm for any answer!
@@SkatterBencher I am in need of some advice if you can. I am pretty frustrated at this point as I run a -35 negative curve on all cores (it is actually stable both on light and heavy load) but I run into the VDDCR SOC VRM showing 1.240V - Is this safe? I updated to the very last bios firmware. I also believe that HWINFO shows wrong values because I have spikes of VDD 2.155v, SOC voltage 2.480and misc voltage 2.220
@@SkatterBencher Hey again. Yeah so I figured out those HWiNFO values only seem to have happend in combination with having AMD adrenalin overlay open at the same time which I simply forgot to disable as I completely wiped my PC after going from 5900x to 7800x3d but now all values seem to be fine and I believe I just panicked because the values were like 2x of what HWiNFO originally gave in the start which is quite concerning especially when HWiNFO was updated to last version and mobo firmware was flashed in the very beginning. Thank you for your time and reply tho!
there is a smidgen of extra performance in manually tuning memory, because EXPO profiles are not good enough. Although the effect of memory tuning is greatly reduced on x3d chips, its still greater than 0.
Hi all. I have Rog Strix x670e-e gaming wifi mobo, 32 gb ddr5 6400 cl32 G.SKILL ram, ryzen 7 7800x3d. On current bios 1416 I am able to achive roughly 5335 mhz clock per core on my cpu. Using strategy #3 from this video, didn’t want to try manual core by core settings so did all at once. So my setup is also 6200 mhz, since 6400 mhz was not stable in DOCP I profile (mobo does not have EXPO for some reason, but it is esentialy same thing just different name for Asus). Precision boost overdrive - enabled, curve optimizer - all cores, negative, and i did 25 magnitude. Tried 30 did pass cinebench R23 but in idle crash, 35 magnitude crash instantly, and 25 was stable for me. I can probably go higher on some cores, and some not, but as I said, i didn’t want to do manual per core overclock. Managed to get around 3.25% (give or take) boost in performance (not counting gpu overclock) and from around 5000 mhz max core clock speed to 5335 mhz per core. Temps stable, droped i think 2-3 celsius from 88-89 to 86-87 in full load Cinebench 23. Idle startup is around 45-47, normal to heavy workload 65-75 celsius and veryhigh workload 86 celsius. Cinebench R23 score - before cpu overclock somewhere around 17400, after overclock 18051. I do not play highly intensive games, and even without OC i had enough fps in games, but did it anyway just to check the results and pass info here since there is almost none cpu overclock videos of this cpu after this fiasco with Asus and their burned up cpu and mobo. I couldn’t hit chinebench 23 scores he hit in this video, but i think that is due mobo diference (his is higer rank and have 20+2 A teamed power solution rate while mine have 18+2 , maybe clean windows 11 instalation, and some other thing, I don’t know, I am not expert, and don’t even know is that ever relevant for cpu overclock, but I have seen my cpu hit 18200 (give or take) score in Cinebench R23 when we put sistem together and did first few testings. Hope this helps someone.
I don't know the specs of that board by heart, but if it has the external clockgens for async eclk then it should be no problem to replicate the strategies. Whether you can get the same results will of course depend on the CPU :)
great video, many thanks! But "asus x3d oc profile" can be enabled independently from PBO2. So what happens if for example both "PBO CO" and "asus x3d oc profile" are enabled? which one is used?
Hey, thank you for the great video! One question about the Bios/UEFI you used. I have the ASUS B650E Gaming and I can't turn on AI Overclocking because the "X3D chips does not support OC". Did you use a specific BIOS/UEFI, or is it limited to x670E?
@@SkatterBencher In the meantime I found a way. The menue has an other name. Unfortunately I can't set eclk to asynchron. On the asus B650E is no Option for that. It looks like the B650E has only one click generator. Or maybe it's only a bios/uefi thing and Asus don't want that option on "cheaper" chipset.
Hi SkatterBencher. Love your content. Looking to perform my first overclock on 7800x3d. I know you use the EFC to monitor ambient and coolant temps. My question is, the EFC only has one header for an external temp sensor which I understand you use for coolant. So where or how do you measure the ambient room temp? I understand the EFC has a second on board sensor. Is this what you use? If so, where is the EFC mounted in the machine and is that a true ambient temp?
Hi Joseph, I indeed use the ambient temperature sensor on the EFC-SB. I don't mount the fan controller anywhere since I'm always using a test bench system. But the fan controller is always in the near vicinity of the system.
Thank you kindly. I have setup an ambient temp sensor based on your advice. I’m using the Aquacomputer Quadro. I’ve tested my settings in stock form. My only other question is about Shamino’s Boost Curve tool. I understand this is an Asus tool. I have an MSI board. What tool can I use to track the average frequencies? Many thanks!
I've found that the tweaked expo profile from asus bios does actually provide substantially better memory performance at least in memory benchmarking, have you tried it and found any impact on cpu performance?
I've tried EXPO Tweaked (or XMP Tweaked) in one previous OC guide but can't remember which. I didn't see it have impact on CPU overclocking. But then again, I did not test very thoroughly.
Thanks man. This was an awesome resource for myself as an ASUS x670e-e Gaming WIFI MOBO + 7800x3D owner. I'm a novice at overclocking and didn't have a clue about which settings to tweak in the BIOS to get a good overclock or about which overclocking method I should use. By the expert way you compared the steps to each overclock method with the results, I can easily determine method 3 (PBO Curve Optimized) is the best one for me. That seems to be my sweet spot for thermals, results, and work invested. If also have GSKILL Trident NEO 5 DDR 5 6000 with EXPO memory. I saw that you used the EXPO1 setting for the memory but I have seen others use EXPO 2 for their overclock. Can you tell me why you used EXPO1 and what the difference between the 2 is? Thanks again brother. This was a tremendous help.
Cool, I use the same configuration as yours, were you able to lower the temperature of yours? Mine is on the 50° scale in a normal process, could you tell me?
@@Paulo0032 I have the same config too... playing metro exodus my PC-Case was getting way hot. Then I changed the curve opt. to -25 on all cores and limited the PPT to 85w. The game did not change and my PC case only gets warm now... The indicator on the x670E-E shows 50-52 ºC while gaming. I'm happy... and I didn't even try -30 or 75W. =D. Let's see if the system is stable first (did this change yesterday)
SkatterBencher Would you answer one more question for me please. Is there a difference between PBO Enabled and PBO Enhanced (70-80-90c) on an Asus motherboard for the x3d chip or a regular chip.
Did you experiment with the max frequency boost setting on the 7800X3D at all? I was surprised to see it not mentioned in this video, considering how much detail and thought has been put into it.
Great videos man, i really like your methodical presentation you must be a teacher, either way makes it really easy to follow and im learning allot from your SkatterBencher series thanks!
How about a modern update for this processor due to the recent BIOS updates bringing extra features and stability. Hopefully its something you'll be willing to consider. 🙏
Not in combination with Precision Boost, because the PB algorithm relies on the voltage to estimate the appropriate frequency. With positive curve optimizer, you set the voltage for a given frequency higher. So if the algorithm determines a maximum allowed voltage, the actual maximum allowed frequency will become lower.
Is it correct to affirm that the strategy 3 is the optimal strategy for anyone who does not want to consume time on fine tuning? Also, I heard that CO ranges from +30 to -30, yet you can still set higher numbers like in your case -35 but in this situation the actual applied value would be -30. could you please verify this piece of information and confirm to me if that's true or false?
OC Strategy #3 is the most balanced in terms of extra frequency and effort required. Correct! +30/-30 used to be the range, but on Raphael it's a bit different. In my Ryzen 7000 launch video I showed up to -300 (three hundred) worked. However, this can change with different AGESA code and I think now the range is more like +30/-60. skatterbencher.com/2022/09/26/raphael-overclocking-whats-new/#AMD_Precision_Boost_Overdrive_2
U have some settings, that i dont have on my B650E-F ROG. Like x3d OC and elck2. Is this a Motherboard or Bios thing? Cause my Bios is on the recent update 1408. Would like to here some nice respond. Thanks for the Vid!
Unfortunately only ASUS 670 boards have extreme tweaker in the bios. I have the same board and opted for OC strategy #3 of the video. Not only do we gain a few frames in gaming but the CPU runs cooler by 5 degrees even at idle. Also for even more performance I applied buildzoids memory timings to the RAM. UA-cam "Easy memory timings for Hynix DDR5 with Ryzen 7000" for his guide. Enjoy!
I have a ASUS ROG STRIX X670E-E GAMING WIFI but doesn't own a cpu for it yet. I wonder if this motherboard will have similar overclocking potential? Would a AIO 280mm be good enough for max overclocking this cpu? I don't think I can fit a bigger AIO in the case.
@@SkatterBencher Hum okey nice! I didn't have the time to watch the whole video in detail. I will do that now. But here in Sweden it became a paper launch and no accurate info on when they're suppose to arrive either sadly.
Hi, the video just came accross my facebook page few hours ago and I'm still new here Why do you limit the Ram frequency lower than EXPO settings ? Is there some effect to the end result to the overclocking the AMD X3D processor ?
While our memory kit is rated at DDR5-6400, I had to run it at DDR5-6200 to ensure stability, as my CPU wasn’t stable at higher memory frequencies. Not all Ryzen CPUs can easily run DDR5-6400.
I'm using the latest bios 1516, and it doesn't have the "core voltage" option for 7800x3d on the GENE board. I noticed that in the video you are using bios 1002. I'm afraid to go back to this old bios because of the melted cpu problems. Is there any hidden option to release the core voltage, or is it blocked in this bios? Is there any trick to release it?
Hello, what was your bios version ? 1101 is instable and does not allow me enable EXPO. When I do it it does not reboot stucks at black screen and if I load overclock preset it gives BSOD.
Hello! I just wondered if you plugged in your second power cable, one 8 pin and one 4 pin to the motherboard? One 8 pin can handle 150Wattage, but not over i think ?
It most certainly can but I’d still plug in the extra 4-pin if you are able to. Less current through the 8-pin meaning less heat/power used to supply the proper voltages to the CPU itself (that is unless it only utilizes the 4-pin after the 8-pin is maxed out, I don’t know how it operates) . If you’re not overclocking it probably doesn’t matter, but if you’re on this video I’m assuming you are and would recommend plugging it in.
What good is overclocking to the max if it isn't stable 24/7 ? Not everyone has the money to waste when the CPU breaks do to overclocking too much. Tell us about 24/7 overclocks that last year's not minutes.
Let's assume there are two V/F points: 5000 MHz at 1.25V and 4500 MHz at 1.15V. Now we use Curve Optimizer to undervolt the processor by 100mV. Then these two V/F Points will become: 5000 MHz at 1.15V and 4500 MHz at 1.05V. We get a lower voltage at a given frequency: 5000 MHz = 1.25V -> 1.15V We get a higher frequency at a given voltage: 1.15V = 4500 -> 5000 MHz
Hi and thanks for your work ! Could you please tell us more about Shamino’s Boost Curve tool, where to get it and how to use it, I can't find anything about it on the web. Thank you and best regards.

Bingo! Thing that i was missing in ECLK OC was increasing per-core CO for failing core...Thx!!!!... I assume you can have smaller ECLK increase, and per-core CO might stay into minuses or you can have bigger ECLK and some of the cores have to move into positive CO . How do you determine max ECLK? at what point are you stopping? As CPU is voltage sensitive are you stopping at first sights that CO needs to go into positives?
Great question! And the boring answer is: it all depends on your CPU :) When you're pushing ECLK and you find there's a bunch of cores that are hitting the fmax, then it makes sense to continue pushing up the eclk to get more frequency. Then start giving the worst core a positive CO. However, if there's only one or two cores hitting the fmax, then it makes sense to leave those be and use negative CO to push up the others a bit.
Love the way you repeat the BIOS setup from scratch for each option. Plus the detailed descriptions. Great vid!

I really like your way of explaining things and amazing that you share your OC:s with the world!
The only thing i would personally prefer is that you made the OC on a non closed loop liquid. The majority of ppl doesnt have that good cooling so doing what you recommend with for example an AIO could destory the system.
Amazing video, thank you so much for taking the time to share your knowledge. You explain everything so throughly, very helpful.
Thanks so much, using the PBO Curve optimsed method I got a stable overclock and CPU temp reduction. Many thanks,

thanks for putting these amazing videos and tutorials out. really is the best out there!
Maybe you've covered this in another video, but can you explain your method for determining your per core curve optimizer offsets? (Or direct me to it) or is it exactly as it seems and is just a time consuming and tedious process if you truly want to have every core at the edge? I'm curious to know your process either way.
It very much is a tedious and time-consumption process. The specific tuning process depends a lot of the specific CPU, because I find that some CPUs are more sensitive to different types of workloads (SSE, AVX, etc). But my general process is pretty simple:
Set negative all core curve optimizer, then check stability with Prime95 small ffts no avx for each core separately (affinity). I just check for 20sec because I'm only interested in whether it crashes immediately or not. Then, as long as all cores pass, further increase the negative curve optimizer in steps of 5.
Then, when 1 core fails switch to per-core curve optimizer and back down on the one core that failed and keep going with the others.
When you have a configuration that works for all cores, it's time to double check stability in various scenarios. I usually do:
1) Per-core SuperPI 32M, to check high-boost stability in light workloads
2) Prime95 small ffts all core non-avx, to check boost in non-avx heavy workload
3) Prime95 small ffts all core avx2, to check boost in avx heavy workload
4) Run all my benchmarks to ensure stability
For 1, 2, and 3, you can easily spot which core is unstable and then just back down with Curve Optimizer for that core. For 4, it's more difficult, so I just back down 5 steps for all cores to build in margin.
@@SkatterBencher Thank you so much for taking the time to detail this out. I guess I need to reinstall prime95. It's been years since I used it last and I wasn't aware you could do per core testing. SuperPI will be a huge help too because my biggest issue always seems to be high boost light workload instability with my last few builds.
Thanks again. You should consider making this into a video, I can almost guarantee there are a lot of people out there that would love to have this in your usual format as a visual walkthrough for getting the most out of their CO.
I use OCCT and test 1 core at a time, takes forever but works.
@@SkatterBencher What about using Ryzen Master and running the per core optimizer, and either just using Master or entering the offset in your bios?
@@SkatterBencher Just started my 7800x3D build and I would like to say thanks for this. Got a question regarding 1/2/3 though, how exactly do we spot the failing cores? All cores pass with -30 for 5 mins each for non avx but when I start with avx2 with the same settings it crashes(bsod) immediately and I can't tell which core was doing it heh.
god damn that was impressive. excellent work. thats a hell of a great chip
So awesome it can get up to 5.6ghz. Can’t wait to toy w/ mine tomorrow. 😎
Yes 5.6 without a load.
I noticed your cpu soc voltage is 1.35v, with the recent news of the burning chips and expo problems, the manufacturers are hard locking the new bios versions to 1.30v max, was wondering your thoughts on this. Many users are manually setting the soc to 1.25v to be on the safe side at least until more info is known. Thanks for the video.
I've been trying to follow the news about the burning up a little bit (including some of the in-depth pieces). Generally, I'm a bit annoyed with the coverage because there's still lots of speculation and jumping to conclusions. Also, I'm not a fan of calling people "lazy" without evidence. It implies intentional malfeasance.
My opinion is that 100mV difference will never be the difference between "guaranteed burnout" and "absolute safety", unless there is a specific hardware design flaw causing that. Going by the physical damage, it's clear some thermal protection is failing. That could related to a dysfunctional physical sensor in the CPU or some edge-case SMU firmware bug, or something different. But what's it's not is +100mV :).
I look at the BIOS voltage limitations as a way to show customers something's actively being done about it and to shift the conversation to "it's those darned overclockers again". You know ... it's not "in spec" but "out of spec" behavior. I'm not confident we'll ever know the true root cause of this issue. And, honestly, I don't really care that much about the root cause being known by the public. I'm just a bit worried that this will further detract AMD from actively investing resources to enable great overclocking experiences.
@@SkatterBencher Thanks man, appreciate you taking the time to answer.😀
Great video, with tons of information. Recently built my first PC in over 20 years and my specific 7800X3D CPU can take a max negative curve optimization of -25 all core when running EXPO tweaked profile. -30 and greater seems to cause stability issues when benchmarking in AIDA64 Extreme.
Thank you for this incredibly useful information. Although I cannot find eCLK configurations on my MSI b650-P WIFI, this video inspired me to increase my base clock via the FCH option available to me. I performed a moderate increase of 102, which sped up the entire system just a touch. I used Ryzen Master to understand my best cores, and used HWINFO during gaming to infer the remaining cores capability. My CPUS cores in ordered of best to worst are 2,4,1,3,5,6,8,7 so I simply set a moderate curve optimizer of -5 and -0 for top 2 cores and +5 for the remaining cores. Very stable, no WHEAs, and increased boost clock to a bit over 5200.
Thank you again!
Hello my friend can we contact in discord can you send me your discord please

Have you thought about delidding the CPU?? From other videos I've seen, at least for the non 3d variants, it seems to be more or less free performance, or free power/heat savings. Would be fun to see you maybe push this processor even more, or see how much lower temps/power draw you can get which is quite important for sff builds.
I've thought about it, but don't have the time to do it
I'm very interested in doing this since mine runs on a fractal ridge case. The ihs seems to be too thick to allow height compatibility with coolers, so removing it already benefits heat transfer
You are always first lately, love it!
I try
Almost ready to receive my CPU, I'll be trying all of this strategies for OC. Thanks for the guidance.
Good luck!
How likely are these strategies to brick your cpu? Ranging from ‘pretty darn low you’ll cook your cpu’ through to ‘try at your own extreme risk’?
@@Dodgerca With zen 4, even if you add + voltage to curve optimizer it will not go past the hard cutoff. Temps also will hard stop at the maximum temp. Unless you really go out of your way to disable default protections, it's going to be rather difficult to kill one. The thing that works best for zen 4 is PBO + curve optimizing, maybe eclock if you have it on your board as well, and with these it's very safe.
Nice work, I also got my 7900x3d to 5.4Ghz with a 106.4 ECLK and did a negative 100 clock on CCD1 so it would not go over 5.95Ghz and crash.

Early bird collects the clicks...
You're gonna blow up your CPU and MB.

I wish eclk was still effective on this cpu for multi core workloads, sadly not the case. Even if i copy your exact settings (theyre not fully stable for me) i dont get anywhere close your frequency, im getting 4620 effective in p95 avx disabled, whereas you were getting 4850.

Ryzen Master has a Curve Optimizing feature that will give the most performant voltage curve per core. I recommend using it because it was very accurate versus my manual tuning would have saved a lot of hours of testing.
For me, Ryzen Master has no option to optimize the curve. I heard that it's disabled for X3D CPUs. Got any ideas?
Looks like it is only for 5000 series
Ryzen Master on 7000 should only be used for viewing, pressing "Apply" garbles the BIOS nvram on some AM5 boards (all ASUS in my experience), and you wouldn't be able to boot until you clear CMOS.
Those game results are a bit perplexing, one would assume there would be much higher differences. Either way, fantastic tutorial.
so is eCLK mode now a standard feature across X670E? Great video btw really clear and informative...
It is not, still stuck as a halo feature. For example it's not on the MSI Carbon ($480) but i heard that it's on the Ace ($700). This Asus board also costs about that much.

@@plushquasar653 is that with the PBO ECLK method?
Great video. Helped me to understand what all the acronyms meant. My old 2600k was the last OC I have done. But it has been purring at 4.4ghz under an AIO for 10 years. It idles at lower temp than the 7800x3d which is also under an AIO. But seeing boost to 5150mhz using PBO2 curve at -30 and a 102mhz base clock. Ran p95 at up to 70c for 5 minutes. I am curious what I can undervolt to now to drop a few more degrees.
I would like to know if I could OC just the boost. So it has a 5500mhz ceiling but idle and surfing the web only uses stock speeds for the most part.
I'm on a 5800x3d but plan on upgrading to a 7800x3d when the time is right- love all your videos you're a legend but I do have one question- does pbo on am4 introduce any sort of added system/input latency? I'm a competitve fps gamer and currently run my 5800x3d with SMT disabled no PBO etc.
I guess in theory PBO/any overclock should actually lower input latency as it's effectively the same as having a higher IPC on a CPU?
I spent years dealing with/learning about multi CCD core-to-core latency penalty w/ a 5950x before realizing that the slugish aim I was experencing in FPS games was actually the result of higher than usual DPC/system latency due to the fact the game was running on multiple physical + virtual cores and communicating across multiple CCDs.
And i've recently started learning about processor IPC and how intel is generally better for gaming because of a higher IPC.
What I can't wrap my head around is what is the 'definitive' way to determine which modern process- thanks in advance!
Newbie here, so from what I can take in, this is a rather hit and miss proceedure with the only monitoring feedback that its working is temperatures, but it could still render your system unstable or even damage your sockets because you are driving them beyond their specified power/current limits? So ultimately, you could be reducing the lifetime of your CPU and motherboard?
CPU overclocking complexity is increasing precipitously.
I mean, it used to be WAY harder back then, then it suddenly got extremely easy (and boring)... And now it's getting a little bit harder again 😂
DDR5 overclocking has entered the chat.
@@PREDATEURLT Yeah I don’t know about that one, EXPO/XMP on DDR5 is hot garbage so even if it’s *only* 10-20% cumulative you’ll more than notice the uplift in 1% and 0.1% lows.
I just learned a new word, thanks!
@Triston Davis No. You don't notice a drastic difference on 0.1 or 1% lows. OC'ing CPUs and tightening timings on ram isn't as beneficial in games as it is for editing/production software.
Gaming, you may gain 10fps after already having 110fps. You won't notice.
Back when you used to have to solder CPU pins together to unlock them, you could go from 2.0GHz to 2.8GHz. You'd get a 40% uplift.
Now people are all excited over 9 or 10% 😑
On my 4790K I went from 4.0GHz all core OC to 4.4GHz (10%) and gained 4fps at 1080p and 3fps at 1440p on AAA titles with a 1080 Ti. With CL7 1600MHz ram (later used 2,400MHz CL11).
Why did you choose Expo I vs Expo II? Btw, I just found your UA-cam channel. I had read your OC information but did not know you had a UA-cam channel. Visuals are always better than just words. Much appreciated.
No particular reason why I picked EXPO I over EXPO II. I usually stick with the first option unless there's some issues
@@SkatterBencher Ok. I asked because my research found that there are differences between the 2 and I was curious if Expo 1 was a better option.
I love your videos regarding undervolt and overclock! Amazing work!
However I am stuck with one question I ask myself after looking at this video twice.
For pure gaming purpose I assume you would go either OC Strat #1 (The easy way) OR OC Strat #3 which takes some more time to find the perfect negative curve I assume?
Tyvm for any answer!
You're spot on :)
@@SkatterBencher Thanl you so much for your answer.
@@SkatterBencher I am in need of some advice if you can. I am pretty frustrated at this point as I run a -35 negative curve on all cores (it is actually stable both on light and heavy load) but I run into the VDDCR SOC VRM showing 1.240V - Is this safe? I updated to the very last bios firmware.
I also believe that HWINFO shows wrong values because I have spikes of VDD 2.155v, SOC voltage 2.480and misc voltage 2.220
VDDCR_SOC 1.24V is safe, yes.
Those HWiNFO values do seem off. Maybe there's a newer version available to download?
@@SkatterBencher Hey again. Yeah so I figured out those HWiNFO values only seem to have happend in combination with having AMD adrenalin overlay open at the same time which I simply forgot to disable as I completely wiped my PC after going from 5900x to 7800x3d but now all values seem to be fine and I believe I just panicked because the values were like 2x of what HWiNFO originally gave in the start which is quite concerning especially when HWiNFO was updated to last version and mobo firmware was flashed in the very beginning.

So whats the best Setting for Gaming ? 7800X3D asus B650E E Gaming
there is a smidgen of extra performance in manually tuning memory, because EXPO profiles are not good enough. Although the effect of memory tuning is greatly reduced on x3d chips, its still greater than 0.
Hi all.
I have Rog Strix x670e-e gaming wifi mobo, 32 gb ddr5 6400 cl32 G.SKILL ram, ryzen 7 7800x3d.
On current bios 1416 I am able to achive roughly 5335 mhz clock per core on my cpu.
Using strategy #3 from this video, didn’t want to try manual core by core settings so did all at once.
So my setup is also 6200 mhz, since 6400 mhz was not stable in DOCP I profile (mobo does not have EXPO for some reason, but it is esentialy same thing just different name for Asus).
Precision boost overdrive - enabled, curve optimizer - all cores, negative, and i did 25 magnitude. Tried 30 did pass cinebench R23 but in idle crash, 35 magnitude crash instantly, and 25 was stable for me. I can probably go higher on some cores, and some not, but as I said, i didn’t want to do manual per core overclock.
Managed to get around 3.25% (give or take) boost in performance (not counting gpu overclock) and from around 5000 mhz max core clock speed to 5335 mhz per core. Temps stable, droped i think 2-3 celsius from 88-89 to 86-87 in full load Cinebench 23. Idle startup is around 45-47, normal to heavy workload 65-75 celsius and veryhigh workload 86 celsius.
Cinebench R23 score - before cpu overclock somewhere around 17400, after overclock 18051.
I do not play highly intensive games, and even without OC i had enough fps in games, but did it anyway just to check the results and pass info here since there is almost none cpu overclock videos of this cpu after this fiasco with Asus and their burned up cpu and mobo.
I couldn’t hit chinebench 23 scores he hit in this video, but i think that is due mobo diference (his is higer rank and have 20+2 A teamed power solution rate while mine have 18+2 , maybe clean windows 11 instalation, and some other thing, I don’t know, I am
not expert, and don’t even know is that ever relevant for cpu overclock, but I have seen my cpu hit 18200 (give or take) score in Cinebench R23 when we put sistem together and did first few testings.
Hope this helps someone.
Correct me if I’m wrong but if you set pbo to enhancement & then set it to your motherboard - the motherboard will limit the CPU’s potential ?
amazing video - very insightful!
Do you think that with an Asus rog strix x670E E Gaming motherboard you can achieve the same results? excellent video 👍
I don't know the specs of that board by heart, but if it has the external clockgens for async eclk then it should be no problem to replicate the strategies. Whether you can get the same results will of course depend on the CPU :)
great video, many thanks!
But "asus x3d oc profile" can be enabled independently from PBO2. So what happens if for example both "PBO CO" and "asus x3d oc profile" are enabled? which one is used?
Hey, thank you for the great video! One question about the Bios/UEFI you used. I have the ASUS B650E Gaming and I can't turn on AI Overclocking because the "X3D chips does not support OC". Did you use a specific BIOS/UEFI, or is it limited to x670E?
I'm not familiar with that error message or issue. Can you share more about it? (Ai Overclocking would be the option to enable EXPO right?)
@@SkatterBencher In the meantime I found a way. The menue has an other name. Unfortunately I can't set eclk to asynchron. On the asus B650E is no Option for that. It looks like the B650E has only one click generator. Or maybe it's only a bios/uefi thing and Asus don't want that option on "cheaper" chipset.
To support Async Eclk you need a physical chip added to the board. So it's definitely a cost consideration to add or not add.
Hi SkatterBencher. Love your content. Looking to perform my first overclock on 7800x3d. I know you use the EFC to monitor ambient and coolant temps. My question is, the EFC only has one header for an external temp sensor which I understand you use for coolant. So where or how do you measure the ambient room temp? I understand the EFC has a second on board sensor. Is this what you use? If so, where is the EFC mounted in the machine and is that a true ambient temp?
Hi Joseph, I indeed use the ambient temperature sensor on the EFC-SB. I don't mount the fan controller anywhere since I'm always using a test bench system. But the fan controller is always in the near vicinity of the system.
Thank you kindly. I have setup an ambient temp sensor based on your advice. I’m using the Aquacomputer Quadro. I’ve tested my settings in stock form. My only other question is about Shamino’s Boost Curve tool. I understand this is an Asus tool. I have an MSI board. What tool can I use to track the average frequencies? Many thanks!
Can this be done on the ROG STRIX X670E-A GAMING WIFI?? Good video
I've found that the tweaked expo profile from asus bios does actually provide substantially better memory performance at least in memory benchmarking, have you tried it and found any impact on cpu performance?
I've tried EXPO Tweaked (or XMP Tweaked) in one previous OC guide but can't remember which. I didn't see it have impact on CPU overclocking. But then again, I did not test very thoroughly.
Please include Star Citizen in your test. In Arena Commander in particular. Thks dude.
is there a benchmark version available where I don't have to manually use fraps to get performance data?
Thanks man. This was an awesome resource for myself as an ASUS x670e-e Gaming WIFI MOBO + 7800x3D owner. I'm a novice at overclocking and didn't have a clue about which settings to tweak in the BIOS to get a good overclock or about which overclocking method I should use. By the expert way you compared the steps to each overclock method with the results, I can easily determine method 3 (PBO Curve Optimized) is the best one for me. That seems to be my sweet spot for thermals, results, and work invested. If also have GSKILL Trident NEO 5 DDR 5 6000 with EXPO memory.

Thanks for doing this.
The pleasure was all mine this time :)
would doing the curve optimizer in the postive direction yield better results if I dont care about the extra voltage and temps?
Not in combination with Precision Boost, because the PB algorithm relies on the voltage to estimate the appropriate frequency. With positive curve optimizer, you set the voltage for a given frequency higher. So if the algorithm determines a maximum allowed voltage, the actual maximum allowed frequency will become lower.
Great material. Thank you!
thanks for your nice video.I wanna know which motherboard could be the cheapest to change the eclk ，could you please provide an answer?
excellent step to step guide how to bury your 7800x3d. xD
Is it correct to affirm that the strategy 3 is the optimal strategy for anyone who does not want to consume time on fine tuning?
Also, I heard that CO ranges from +30 to -30, yet you can still set higher numbers like in your case -35 but in this situation the actual applied value would be -30. could you please verify this piece of information and confirm to me if that's true or false?
OC Strategy #3 is the most balanced in terms of extra frequency and effort required. Correct!
+30/-30 used to be the range, but on Raphael it's a bit different. In my Ryzen 7000 launch video I showed up to -300 (three hundred) worked. However, this can change with different AGESA code and I think now the range is more like +30/-60.

Depends more about silicon and cooling not that much about mobo
At worst, when overclocked this CPU pulls only 100W. Any decent air cooler will handle that.
@@SkatterBencher Hum okey nice! I didn't have the time to watch the whole video in detail. I will do that now. But here in Sweden it became a paper launch and no accurate info on when they're suppose to arrive either sadly.
Turning the 7800X3D into a 7700XX3D, I like it!
Is a custom loop the only way to keep the temperatures low on this cpu or would a good aio be enough for light overclocking?
mate it pulls 80 Watts stock, you don't even need an AIO
Seconded, it's very easy to aircool this CPU
Would love a tutorial to curve per core from someone experienced.
You can use something like OCCT with its individual per core test.

Which mobo is the most affordible with a ext clock gen?
Hi, the video just came accross my facebook page few hours ago and I'm still new here
Why do you limit the Ram frequency lower than EXPO settings ? Is there some effect to the end result to the overclocking the AMD X3D processor ?
While our memory kit is rated at DDR5-6400, I had to run it at DDR5-6200 to ensure stability, as my CPU wasn’t stable at higher memory frequencies. Not all Ryzen CPUs can easily run DDR5-6400.
how would one test each specific core? and then optimize each one with curve optimizer?
thanks for the video :D
I'm using the latest bios 1516, and it doesn't have the "core voltage" option for 7800x3d on the GENE board.
I noticed that in the video you are using bios 1002.
I'm afraid to go back to this old bios because of the melted cpu problems.
Is there any hidden option to release the core voltage, or is it blocked in this bios?
Is there any trick to release it?
I'm playing with a 3900X and 4090 in 4K. Do you think its worth to upgrade to a 7800X3D? I could get the 5800 x3d for 284 euros...
For the biggest boost at the lowest price, I’d suggest the 5800x3d. If you’re looking to jump architectures, might as well go to 7800x3d.
Hello, what was your bios version ? 1101 is instable and does not allow me enable EXPO. When I do it it does not reboot stucks at black screen and if I load overclock preset it gives BSOD.
Hello! I just wondered if you plugged in your second power cable, one 8 pin and one 4 pin to the motherboard? One 8 pin can handle 150Wattage, but not over i think ?
It most certainly can but I’d still plug in the extra 4-pin if you are able to. Less current through the 8-pin meaning less heat/power used to supply the proper voltages to the CPU itself (that is unless it only utilizes the 4-pin after the 8-pin is maxed out, I don’t know how it operates) . If you’re not overclocking it probably doesn’t matter, but if you’re on this video I’m assuming you are and would recommend plugging it in.
What good is overclocking to the max if it isn't stable 24/7 ? Not everyone has the money to waste when the CPU breaks do to overclocking too much. Tell us about 24/7 overclocks that last year's not minutes.
Hi, I don't understand why you state at 16:02
Lower voltage for a given frecuency = Higher frequency at a given voltage.
Let's assume there are two V/F points: 5000 MHz at 1.25V and 4500 MHz at 1.15V.
Now we use Curve Optimizer to undervolt the processor by 100mV. Then these two V/F Points will become: 5000 MHz at 1.15V and 4500 MHz at 1.05V.
We get a lower voltage at a given frequency: 5000 MHz = 1.25V -> 1.15V
We get a higher frequency at a given voltage: 1.15V = 4500 -> 5000 MHz
which bios did you use?
looks like you choose bios 1002 any reason behind it?
No special reason, it's the one that was available when I started working on the guide
Hi and thanks for your work !
Could you please tell us more about Shamino’s Boost Curve tool, where to get it and how to use it, I can't find anything about it on the web.
Thank you and best regards.
It is in the ROG X670E ocpak/octools, which you can find here: rog-forum.asus.com/t5/amd-600-series/x670-resource/m-p/901576 > ocpak/octools > DB Query > AMD V/F > Get Boost Curve.
@@SkatterBencher Excellent thank you very much 🤘🤘🤘
FYI I've grilled my CPU by using the Get VF function of Shamino tools. Be careful.
Bingo! Thing that i was missing in ECLK OC was increasing per-core CO for failing core...Thx!!!!... I assume you can have smaller ECLK increase, and per-core CO might stay into minuses or you can have bigger ECLK and some of the cores have to move into positive CO . How do you determine max ECLK? at what point are you stopping? As CPU is voltage sensitive are you stopping at first sights that CO needs to go into positives?
Great question! And the boring answer is: it all depends on your CPU :)
When you're pushing ECLK and you find there's a bunch of cores that are hitting the fmax, then it makes sense to continue pushing up the eclk to get more frequency. Then start giving the worst core a positive CO. However, if there's only one or two cores hitting the fmax, then it makes sense to leave those be and use negative CO to push up the others a bit.
@@SkatterBencher what are the signs that a particular core is hitting fmax?
“Power is proportional to the square of voltage.”
Only for linear/passive devices friend!
