this channel is like the baby of GamerNexus and hardwarecanucks, technical(topic), elegant(b roll), no BS just tons of usefulness
No.
Don’t say hardwarecanucks. They are idiots.
@@navaks5335 link me video that has better B roll than they do
Alan Xu Alan Xu who cares about “b roll”?
Just because they have fancy video editing it doesn’t mean their channel is good.
Also they often overstate things, other times they completely avoid really useful information (idk if they do it intentionally or not but still).
And their channel. Called “Hardware Canucks”. A Canadian channel “in theory”, run by two foreign guys.
@@navaks5335 every single channel cares about b roll. otherwise why every video has them
Alan Xu you seem more interested in video montage than the actual content. If you cared at least a little about info you wouldn’t say so.
Never put gamernexus and hardwarecanucks in one sentence cause it’s blasphemy. Unless it says “GN is great while HC is trash”
Dude, every time I search for in depth and reasonable explanation about GPU or CPU performance, temps or whatever since I need a new PC, I find myself coming back to your channel. There's just too much good stuff here that I can't seem to find elsewhere. Nobody else cares to cover all this in this depth. Keep it up!
at 1.23v my 9900kf won't even post yet yours is stable under load ? I find that hard to justify with just silicon lottery alone
It's about time a reviewer showed realistic voltage instead of just forcing whatever voltage it takes to get 5ghz. Reviewers are saying it runs too hot on a weak binned chip running 1.4v. I've said this since the chip came out that if you push whatever clocks you can get at 1.2 to 1.25v the temps will be well within check and even weak chips will likely do 4.8ghz at that voltage. Problem is most reviewers just slap some numbers in and don't actually have real experience overclocking. It's not about getting that glorious 5ghz no matter what that's for sure.
the worst is unboxed hardware..this guy does good job
I barely get 4.9 stable @ 1.3v on noctua nhd15. Air cooler yes, but I think if the reviewer spent more than 20 min on an aio he might run into problems at that temp? Or maybe he's just really lucky/I'm unlucky/both. Either way I think aio testing should be done for at least an hour...
Very true compared to air or land, water is a slow conductor of heat...
whodawhathuh Just got mine. Have an old EK 360 Loop hooked up to it and still it runs hot. Lousy software, but used a voltage offset to finally get 5Ghz at around 1.296V. Honestly the numbers he’s showing make me depressed. 5Ghz at 1.23V? He needs to admit he got a golden sample.
@@Aurummorituri yes... well that and he didnt run the tests long enough to even reach equilibrium on his water cooler... then again... if my chip wasn't so much worse I wouldn't even be salty so sucks for us I guess... btw... I think 5ghz at 1.3v and below is great... congrats!
that's a golden chip you have there.
every new product launch its so fun to watch the high success rate of reviewers with golden samples LOL, we all know the game they play but they do it anyway.
I suspect my chip isnt too bad, I started with 1.25v on stock no issues, bumped all core to 4.8 whilst also boosting 4 core to 4.9, and I noticed XTU kept boosting to 4.9 and no crash, so this chip "probably " can do 4.9 on 1.25, which I will do next, and if it does its probably at least above average.
However I have already decided I wont be boosting the voltage, so I will go as high as I can on 1.25v, and not try to boost voltage to get past whatever ceiling I hit, its just real nice already to have this chip which is so much cooler than my 8600k which needed 1.37v to run at 4.7.
Yeah not all of us are obsessed with hitting 5ghz and sticking 1.4v to get there lol.
My 9900k is a hotter chip than my 2600x, but I wouldnt consider it a gulf. The main issue I think is the motherboard vendors are for whatever reason applying massively high stock voltages.
Not surprising since it was provided by the motherboard company he’s testing.
I’m not sure if I got a golden chip but I bought a 9900k today used from someone who had it since July,2020 and I got 5.1ghz at 1.3vcore very stable at 64 max temps
Aorus Gaming 7 & NZXT X73 cooler so those two probably helped me
The big reason why I went with Intel prior to the Ryzen release was heat and power consumption in the AMD CPU's of that era. Now it seems like things are reversing.
Nice to see undervolting. Not many people even realize they can run at stock clocks with way lower voltage. Reduces temps. Extends life of motherboard VRMs, reduces noise from fans and doesn't compromise performance.
Been running my 4790k with a -0.07V vcore offset for years. Hits 4.5ghz single core 4.4ghz all core around 1.1V. Not bad for the older 22nm Haswell.
Vrams cooler and extends lifespan.. So your Vrams have maybe 5 c less than usual mob.. So u gain nothing in lifespan.. Vrams are made stand big heat.. Oh come on it's an 21 century.. Don't be silly
It's a z97 mobo, they didn't put big gawdy heatsinks on the VRMs back then. There's actually no heatsink in the vcore vrm at all. Unlike today where they slap 500g of aluminum on them. Though, you're right, most modern motherboards will be fine. Caps and VRMs haven't failed in large numbers since the 90s. They do have a finite lifespan though. VRMs and caps are typically rated for ~2000 hours at 95-100C, more premium boards they may be more like 5000 hours at 120C. I know my system has been on far longer, probably ~8000 hours. So keeping it cool will help ensure it lasts without question.
@@ericwright8592 dont forget that the Vcore when iddle or light use is usually below 1. an generally anything below 1.3-1.32 under full load is still okay
Any chance you could teach us how you establish the undervolt and overclock procedure that lead you to the graph? I’m interested specially on the gigabyte board, since I just bought an gigabyte auorus z390 master and a 9900k.
same
Dito :)
set your voltage and core speed for all cores manually :-D what else do you expect he will tell you?
Same.
the most important thing on these new chips is to use the power limit more than just an overclock. what i mean is to overclock it as far as you are willing to go as far as voltage goes. the 8700k is smaller but its all i have so ill use mine as an example. itll clock to 5.1gh at 1.33v and be stable in everything. its a very good chip and i have a decent board for it.
now if i had a lesser board or heatsink, or if it was a 9900k here is what i would do. i would leave that clock as is but lower the power limit from unlimited down to the max my system could handle. my system handles up to about 200w without breaking a sweat and and can handle over 230w for short periods but i wouldnt wanna do it for too long. so i set the maintained or long power limit to 220w (or 230w but 220w is a lot already) and the time period to maybe 10 seconds. then i set the short limit to 200w.
now whenever you start prime95 or a video encode or anything that hogs the power it will throttle down if it meets the short power limit of 220w immediately. thats as high as it wil go. now if it goes over the lower long or maintained power limit it will draw that power only as long as you set the timer period. so for 10 seconds it can draw over 200w up to 220w but as soon as it hits 220w it throttles or if it stays above 200w for 10 seconds it will throttle. in a video encode it will stay up near 5.1-5ghz most times but for prime it will drop down depending on what kind of test you are running. some will stay at 5.1ghz and some will throttle down as low as 4.5 (but prime is the only appo that will get anywhere near that because its a power hog.
now youre games and normal apps on the desktop? they will always stay at 5.1ghz (or whatever your max clock is) because no game made will use more than about 120w max on even a 9900k. games arent that power hungry when it comes to cpus.
so now you have a system thats overclocked to the max you could get but you dont have to worry about it melting if you run a heavy workload on it as well. it will take care of itself
now the big question is how do you find what is the limit for your system. to be honest most people with a high end system will be able to use my numbers for a 9900k. for gaming most definately. but if you run anything power hungry you really need a good board with good vrm cooling and airflow. you also need a really good cooler. you just have to run the system with an app to monitor power draw and heat of the cpu and vrms. if the cpu hits 70-80c then whatever power level you are at is your long or maintained limit. whatever power number your system hits 80-90c is your short limit. i set my long\maintained so it wwould get mid 70's and the short limit so it would maybe hit low 80's. you can do more but i wanted it a bit cooler.
as far as finding voltage for your cpu you just have to experiment. try around 1.3v for 5ghz with an avx offset of 1 so it will downclock to 4.9 when doing avx loads. if it is stable then maybe try having no avx offset. if thats stable then see if you can get 5.1 with a avvx offset of 1. if thats stable then raise the avx offset. if you are ok with a bit more voltage than 1.3v then go up a bit and rinse and repeat. get the most clocks you can with the lowest voltage. thats it. oh and you have to test with seomthing to make sure the cpu is stable everytime you raise the voltage\clocks. intel xtu is a good one that has a memory test in it but doesnt try to destroy your cpu lime prime95 does. but if you have your power limit set right then prime wont draw enough power to wreck your cpu but it will throttle which doesnt really test the clocks. so you need to have the power limit raise to max for this part. inte xtu can find unstable memory without baking the cpu and wrecking your vrms like prime does
Mate great videos, good to see an Australian reviewer! I’ve subbed, Mark from Tasmania.
hell yeah, i love your channel man.
I don't understand why you have only 70k subs, underrated!
btw,
i'm literally copying your pc setup you showed i while ago in one of your videos haha
I need somewhat similar gear to yours + i love the look and feel of it 😍
Greetings from Italy!
Really appreciate the kind words. Feel free to reach out if need any help with the build.
Please review the 9700k next, as I have not found any videos comparing the 9900k vs 9700k in thermals and giving advice to consumers as to which chip has better thermal stability and which one can overclock better with stable temperatures. I purchased the 9700k and have not built my system yet and I hope I can get a higher overclock with it and lower thermals than the 9900k. I would also possibly like to do 5.2 Ghz on 2 cores and run the remaining at say 4.7Ghz or so, just an idea I had in my head.
9900K runs hotter for sure.
It seems that Optimum really got a good sample. Mine hits 5GHz @ 1.23V non AVX. 1.3V for AVX. My asus hero XI says that chip quality is about 110% but looking at Optimums numbers he looks like he's closer to 150% :O
That chip is one hell of a golden sample.
speaking of intel and bad thermals I kinda want to delid my I3 just to figure out how de-lidding goes for later, want to later get a I7 6700 and actually finish that ghetto home server build.
I practiced on a Pentium G4560. No shame :)
Adam Khan no shame do it..
Man, the statistics and graphs are so clear and useful. I love your content.
Ive been waiting for your 9900k video!!
Mine just arrived in the mail and i scored it for $770aud. I have a 700mm of radiator custom loop on the way to hopefully keep this bad boy under wraps at 5.2ghz
Nice! Where'd you score it for $770?
@@optimumtech After waiting a month for my pre order not to be filled yet a guy posted on gumtree after using it for 2 days it wasnt good enough for rending/timeline 8K RED camera footage so he was going X series. So i nabbed it. Happy with that :)
Mini ATX? im using midtower i9-9900KF currently overclocked as well, and i had to add 2 more fans from above, so the temperature is ok... I cant imagine mini atx, not gonna lie, it will melt something inside by the time.
You got a great chip. I need 1.20v for 4.8ghz on my 9900k. 80c on prime95 with one fan on NH-U14S
According to your voltages, you have GOLDEN sample.
According to Silicon Lottery preliminary stats, ONLY 46% of 9900k can do 5.0ghz or higher in their stress tests.
I have a 9900k 5ghz with zero avx delidded and runs got 93 max for stress testing 50-83c in games
Sweet video! That chips runs crazy low voltages for the speeds you achieved. Gigabyte has made some great z390 boards no doubt. I would be super interested to see what voltage/frequencies it can hit with a less "ideal" motherboard. Would gigabyte allow this?
your channel is awesome, great videos, set, illumination etc like Dmitry and other pro creators
Running z390 aorus pro and 9900k stock. CPU-z shows voltage consumption of as high as 1.380volts when running cinebench r15, hwinfo shows power draw of as high as 140 watts. So basically 4.7ghz at a maximum of 1.360 - 1.380 volts with a maximum power consumption of 140watts. Running absolutely rock stable, but I sometimes think of undervolting, looking for some expert opinion in the subject.
Thanks for this. I have had my 9900k for a while, and while I'm generally fine with the temps I get on my 280mm AIO, I was considering undervolting just to see if I could get better temps. It's a lot harder to find undervolt, or solid stock clock voltage limits that can reduce temps compared to finding safe OC voltages. Had to do similar with my 4670k because the gigabyte board I had let the voltage run absolutely wild...it's been ages, but I want to say I saw 1.43v or near that at one point when I saw the ridiculous temps I was getting.
love your videos!
Still can not understand how can you get those voltages.. im in 1.205 for 4.9GHz
And i cant get the same points in cinebench as you do… what am i missing…
@@MarcNF15 Good cooling probably
@@djangojansen7648 temps are not my problem at all... i play with a 2080 ti and i never reached 60 degrees with my overcloking settings, even playing red dead redemption 2 and im at 55 - 57 degrees, cpu has a 360 aio from thermaltake with grizzly thermal paste.. 45 degrees, maximum of 67 doing cinebench... I supose he has amn amazing cpu.. one of many?
Thermals on the 9900k for me are much better than my old 8700k. The solder deffo makes a big difference. Quite happy with this chip.
Time to start tinkering with my 9900k matched into a Z370 Classified K (full custom loop 420 & 240 rads). Your graphs/numbers look like a good place to start :)
My chip seems to be pretty bad. I'm 4.6Ghz,1.344v, and max 77c. 240 mm radiator cooling with 4 total fans.
5.2GHz on all cores need 1.4V and are not super stable. Temps are in the high 80 to low 90 °C with a 360 AIO. Not that bad for a stock sample. Nothing I'd use 24/7 but a nice result. With a good aircooler I managed to quench 4.9Ghz out of it but it got way to hot. I'd say at least a 360 Aio better a custom loop with a good pump and a big radiator is a must for that beast.
Can you test this in your M1? Wanna see how it performs there with a 240mm AIO.
This is a golden chip lmao. I was only able to get 4.8ghz @ 1.195vcore. Still helped with temps a lot, I cant even imagine how good 4.7ghz would be with a lowered volt, but I'm going to keep it at 4.8ghz.
gotta say this channel gets better and better mate you really know your stuff and give us all information we noobs can understand fo'sho,just wanted to ask if possible your thoughts on using puch pull with an NZXT Kraken X62 as i have this config recently but CAM softwear keeps giving me some odd info in regards to my fan speeds...i have them set to the 'silent' profile because let's face it with 4 NZXT P140 AER fans in push pull using any other config seems overkill,my temps are awesome on my 6700k with 17c at idle but my fans still show odd speeds i relation to the cam on screen info...so maybe a video would be interesting using this config,(obviously you most probably don't have a 6700k lying around),i am sure the same thing can be done with an 8700k or some such...what say you
I’m torn. I’ve scored a i7-9700 non-k for free and built a PC last July. The 9900k was still $800AUD and now they have dropped to $450. Not sure if I should get the 9900k and OC it. I’m running a z390 Gigabyte Arous so it shouldn’t be a problem 😬🤔
This is so useful, you're the best!
Hello excellent video, could you pass some configurations of the mother to go testing. Thank you
Love the feel and content of your videos. always great
Stop using cherry picked sample cpu, use retail cpu!!!
Holymoly s Yeah, his numbers are kinda unrealistic. Barely got 5Ghz at 1.296V, and that is “good” versus some reviewers needing 1.35V+.
@@Aurummorituri yeah mines barely stable with stock and a custom loop 360 rad cpu cooler.
@@Draven2k Sigh. Ended up dropping 4 cores to 4.8, 2 cores to 4.9, and left 2 at 5.0. It's not perfectly stable at all core 5.0 at 1.3V. LLC is too low at 4, but bumping it up to 3 makes the board goose the voltage higher than what I can offset in the bios. I have to use Intel Tuning for that and it requires loading a profile on every login. Really dumb.
Aurummorituri yeah this is actually the best chip I’ve seen on UA-cam and I thought 5ghz@1.275v was a golden chip. And mine is 5ghz@1.3v which I heard is actually pretty good though. (Think I could undervolt a bit more if I try but I don’t have much patience maybe tomorrow)
Lim Chhay OMG UPDATE YOUR BIOS PEOPLE! I am using a Z390 Taichi Ultimate and Asrock released a new bios a couple days ago. Night and day difference on Vcore. Stock voltage dropped from an absurd 1.36V under load to 1.248V! Bumped up LLC to 3 and am running much cooler and more stable. Also 30W less power draw. I thought I had a crappy chip. Just crappy software.
Just got my 9900k. I know that each chip is not the same quality and each requires its own voltage, but your numbers just seem like fantasy. Granted, my ASRock Z390 Taichi Ultimate has crappy software in the way, but...damn. Out of the box my Vcore at 4.7 was the same as yours at 5.2! Also, no adaptive voltage. Static and offset only. So after hours of wrangling with an offset that won’t go below -.1V and load line calibration I’m at 5Ghz at 1.296V. Might I inquire of your method of setting voltage as well as your cache clock (mine crashed above 48x) and its voltage.
Best COOLER for i9 9900k ? :D
full custom loop with chiller
I would say three stage cascade phase-change cooling would be a good option for ya.
as he suggested for an AIO - 360mm (triple fan models)
TT floe riing 360
Fire hydrant
The thing is, and I noticed this after having the 9900k for just a day, is that there is little point to running above about 4.7Ghz all core. Only the benchmark scores get higher. The actual real world performance only barely creeps up. For example, in Resolve, we are talking 3-4 seconds less on a 10 minute render job for every 100Mhz bump all core. Its basically nothing. Silicon lottery? What a joke. If you are buying a 9900k to run benchmarks all day, have at it. If you are buying a 9900k to do actual tasks, landing a "golden" chip means not a damn thing. Im saying this, and I actually think I may have got one of the "better" samples. Although, my "better" 9900k and 5 bucks does buy me a cup of coffee at Starbucks. They keep giving me back the 9900k in change, almost as if they dont want it for some reason. I keep telling them, no, you dont get it, this is a better one. Yeah, they hand it right back, and say please come again tomorrow..with 5 more dollars.
imo the sweetspot is 4,8 ghz at 1.13V. after that the temperature increases dramatically
Those temps are still crazy cool for AVX workloads compared to my chip. I'll easily hit over 100deg with a dual 360 rad loop.
Waiting for the 545LC tests
Wow is this a golden chip? In order to get stable with Adobe Premiere with 5GHZ, my chip needs 1.33V.
Soap A My 9900K goes 1.37V @4.7… 😪 and I forgot to test it when buying, no more returns.
may I ask what lens you are using when you are taking footage of yourself talking. I'm suprised how sharp the image is on my asus pg27uq. Very nice. I have an A7RIII and would like a good vlog lens, but not sure it will work with my camera since its full frame. any suggestions?

@@AllThatJazOfficial I've seen the review and the build in the video. I just thought it was lackluster compared to his usual custom builds as it was very plain and I didn't think it did the case justice. I would like to see what he could build in that case!
@@juniorm5391 check my channel. My Evolv x video is not nearly as high quality but i think my build is. Custom loop and 9900k going in soon
@@AllThatJazOfficial I've actually seen your video! I love that build, although I'm not exactly the biggest fan of tons of RGB. That's why I wanted to see a custom loop from Optimum kinda like his Mute build or Dark Matter because of how his generally clean and minimalistic builds.
Main problem i have with undervolting is that your cpu will always run on the set voltage as offset does not really work because the idle voltage also gets lowered and that makes bootup impossible or the pc crash in windows.
Review after review it's the same thing. Magical less -0.15v required at a minimum and still stable chips, time after time. Cincy Lauper "Time after Time..."
How do I undervolt my i9 9900k.
Do you have a guide for it?
I want it to run at a certain voltage consistently anddontgot above that.
Is that an option? I am new to this.
My OC was stable with 5GHz 1.295v and LL level 7. After ASUS BIOS updates it needs 1.35v
I thought my chip was good part of the golden sample, I am using 9900k for my sffpc build with a low profile cooler.. So I needed to undervolt this thing BADLY. The good thing is that my chip is stable 4.7ghz at 1.15v, I thought that was pretty good until I saw that you got 1.10v for the same clock speeds. Jesus.
The 10th Gen desktop Intel CPU is said to come out next month or so, should I wait for it or just go with 9th CPU? Just kinda feel the IPC improvement wouldn't be too much based on the its the same 14nm CPUs
Youre so lucky, perfect sample! I god bad sample :(, 4.7ghz all core boost @ 1.21V and not less (the same MB z390 Aorus Pro), LLC i set @Turbo... Using 360mm radiator, but tems in blender are about 80'C, i will later try 4.6ghz with smaller voltage, mby there is breakpoint (like on skylake or haswell was - example, 4.5ghz @ 1.2V, but for 4.6ghz is huge voltage bump like 1.29V)...
First time to see your videos, you're really good keep it up :) Subbed!
Try to combine with the z390 auros master with i9 9900k. I compare your review to mine. I get better and lower temps. I'm overclock at 3.2 to 5.2 and my ram 3200 mhz to 3700 mhz. my cooler is custom loop with 360 rad just for the cpu.
I will really appreciated if you or someone can answer my question, I have a 9900k with a ASUS z370 hero x Wi-Fi, my 9900k goes only to 1.17, 1.18v, at stock, my question is, If I get a z390 motherboard will I be able to undervolt a bit more or should I stick with the z370?
very nice detailed video! good job subbed
1.23v for 5Ghz is super lucky!
How can I undervolt my i7 9700K with noctua nh-d15 and asus rog strix z390 F gaming? Because it's hot as hell under load in games.
Just go into the BIOS and lower the voltage
Optimum tech, where do you read the vcore readings off? Cpu-z or hwinfo?
Good video again :) Would it be possible to do similar video about 9700K also? I'd love to see a temp, power draw and overclocking comparison between 8700K, 9700K and 9900K :P
I don't know why but I can't boot or keep mine stable under 1.185V even at 4ghz. should I set any advanced voltage? my motherboard is an asus maximus X hero
So it's advertised as 5ghz turbo stock... is that only one core? Lots of videos saying "overclocked to 5ghz" but thats the stock turbo
5.2Ghz at 1.36v and 5.1 @ 1.29v I'd say you have a much better than average 9900K on your hands. This is one of those top 7% or better chips.
Looking at the power consumption it seems your tests didn't really stress the CPU. Try Prime95 or ADIA64 FPU only. I suspect it would crash in 15 minutes.
Yep, bullshit test. Newest Prime95 and crash after 1 minute :).
@Mike That's not the point. The problem is he didn't stress test at all and claimed it's 'stable'. Mine could run a few cinebench with 4.9Ghz @1.19v with no 'issues' but in order to get no errors or wheas in both OCCT and x264 I need 1.25v. And these two tests are far from being 'unrealistic power virus'.
I’ve tested mine with prime95 and I got a bad chip where even 1.33v under load can’t be stable on all cores at 4.7ghz so I’ve lucky fell into a bad silicon lottery experience.
Cooler: Noctua nhd15s
Motherboard: Asus Prime z370-p
Curious Slyfox I tought that I was unlucky to get i9-9900K which needs 1.2v to get stable on 4.7GHz. : /
how many minites where you on prime? and was it at a set 1.33V or was it set to adaptive ?
That motherboard can not handle 9900k btw
Excellent video! Thanks.
i use a adaptive voltage on my overclock. its stable but you gotta to turn it off if using a stress test like prime 95
Why does it need to be turned off for stress testing? Does it become unstable at 100% load?
Amazing content ty bro!!!
I just got an i7 10700k and it's literally the same voltages and frequencies as your 9900 K here
Why not to buy i9 9900k and then use it at 4.5ghz with 130w tdp air cooler, you don't need more than 4.7 ghz, it just doesn't worth extra power consumption and temperatures...
im allcore at 4,7 with 1,15V under load. im fine to this. maybe i can lower this, but i dont want an unpredictable crash ;D so im very happy to this setting :)
How in the world are you getting these "stable" volts. My chip is mostly stable at 5Ghz, 1.345 8hrs ran on OCCT no avx max temp 91 with my 360mm aio. If i drop below that it crashes. Yet yours is stable at 1.23 max temp 70. I don't understand..
I know of a few 9900ks that can run stable 5ghz at
The timings for the RAM on the graphs around 3:50 was mistyped i assume!
Great vid thought
definitely it's most likely 16.18.18.36 not 26
Can anyone tell me (I'm a noob to all this) if the voltages at 4:43 are the vcore voltages that you put in the BIOS? Or are these the voltages under 100% load (with drop (vdroop)) ?
Love your videos, keep it up!
Can we just get a static OC and undervolting or is it possible to set it up dynamic like offset or curve like they are in amd mainboard.
I recently bought myself a 9900k, however i have a Prime Z370-A motherboard and i dont really want to upgrade to a Z390 because i have a custom watercooled setup with a monoblock to fit the Prime Z370-A. So my quesition is, Can i expect to see close to similar results on my Z370 or am i better off biting the bullet and get a Z390 and put my monoblock aside? i am running a 4.8Ghz overclock but i could only get it stable at 1.375v or 1.4v which makes the temps jump fairly much under load
Hi @alisayed3
Which CPU is better for my Ncase M1, the i7 8700k or the i7 9700k / i9 9900k ?
The Price isn‘t important, i ask just for the compatibility (Temperatures), i have at the Moment the Noctua U9s, but i can switch to an 240mm Aio when i must.
I will not OC the CPU
Can you help me please for this decision ?🙏
Best regards
Just ordered a 9900KF for only 360€
Is this a review sample provided by Intel or a chip you bought yourself? I only ask because I could dream of getting my 9900k to run at those voltages... like Intel doesn't bin their best chips to send out to reviewers, right everyone?
Great video. Hope you do a Ryzen version of this video.
Its really hard to find an oced i9 9700k vids.. theres tons of 9900k vid tho..bruh..can you make 1 ..really appreciate it 😘
If only that chip would be sold as a I7 at the price of around 330-380
Please add Vegas Pro for video benchmark
@optimum tech I ran my i9k at 4.8 and 1.140 v and got 4999cb is that really good?
Great vid dude! Can you make the same for Ryzen 2700X?
Mine is running at 4.2Ghz with 1.325V and "Extreme" load line calibration on the Aorus X470 gaming 7 and I am using the stock cooler.
It gets 1926 Cinebench R15 score but that's with Flare X 3200 CL14 kit (2x8) that is running at 3533Mhz at 1.46V
With CL16 RAM at 3200 it will probably drop the score to 1850s or something.
CPU temps peaks at 78 degrees after 30 min Aida64 on CPU, cache and GPU combined but I have the side panel off on my craptastic 7 year old cooler master case and I have reversed the rear 120mm fan to blow towards the cooler at max speed all the time. Saving money for Corsair Air 740 now ^^ but I don't think I will be buying an AIO.
I could spend £200 more for rads and pumps and fans and only push it from 4.2 to 4.3Ghz and yes it will be a bit quieter but its fine now even while rendering video or streaming while gaming.
It should get even quieter with side panel on and some Noctua fans. I hope. :)
MSI z370 M5 , Game APP Silent Mode killed my i9 9900K (playing PUBG, CPU was stuck to 100%, then system freeze,then boot with dead cpu,code 00)
great video. perhaps I, too, will make downvolt my 9900k, so as me enough 4.7 GHz.
Best decision you could make colleague!
@Optimum tech
please help after I OC my pc when I turn the pc on then it will turn off for 2 sec then boot normally I was wondering if this is nomal on pc with OC setting?, I have Maximus XI mobo, i9900k cpu.
@Optimum Tech Hi mate, I have a few questions I did some OC testing yesterday with a h115i pro 280 aio. 5.0GHz at 1.30v and using Small FFT Prime95 AVX testing with no offset I was seeing temperatures up to 100-109C just before thermal throttling set at 110C in my Bios. But that kind of worried me so I dialed it back. Also in custom Prime95 tests, I'm seeing more like 95-100C max like in the test you did at the end of this video. So with that said I have a couple of questions.
1. Is 110C a couple of times for no more than 15 minutes likely to have damaged my CPU or reduced its lifespan or overclockability? Two test I ran for about 15 mins and the rest was just a few mins at these temperatures before I decided to stop. I'm going to dial in a less aggressive OC or I might delid and direct die cool with a h150i.
2. Is this TjMax of this CPU 100C or 110C I keep seeing conflicting results but 100C from intel but other articles and UA-camrs state 110 or 115C. I also see other data that doesn't seem accurate like boost up to 5GHz when it used to say 4.7GHz for the i9900k.
3. What testing should I do to confirm stability and for how long with temps up to 100C? Is the custom prime95 test you ran the best test on the latest version of prime95? I did this test and I hit around 100C max and it seems to be stable. When I run small FFTs (in the latest p95 version) temps get up to 110C and eventually one of my cores will drop utilization down to like 60-70%, not sure if this is a bug as no thermal throttling happened, which is weird. Running smallest FFTs yields similar results but a couple degrees less and it takes longer for that 1 core underutilization to happen. All my other tests run fine like Cinebench, Intel XTU, etc.
Thanks!
Dude you need to increase your AVX offset, back off your voltages or both. Prime is no good for testing stability anyway. I've seen 24 hr Prime stable machines crash within seconds of playing certain games.
My CPU @ 4.9 on all cores doesn't go much above 80C with an h80i. But then I've never torture tested mine....
I have a i9 9900k turbo boosted to 5 ghz and my temps are always around 113 -130f while gaming is that good?
yes its good
its because gaming doesnt require all 8 cores on full load.
if you try to run a stress test your temps could reach 100 celsius
9900k + maximus xi formula. 2x rtx 2080ti. 1x360 45mm, 1x360 30mm, 1x120 30mm. cpu, gpus, ram and vrm in the loop. dual pump single loop. 5ghz all cores, 4.9 avx, 1.34V. 104C after 30 min blender, avx on, 92C avx off. Voltage any lower than 1.34 will result in calculation error in blender avx off. Guess I lost the lottery :(
Would love a guide for this
Thanks Mate! Had I only discovered your video earlier, then I would have taken instead of 8700 k 9900 k and undervolted.
So I'll probably first at 8700 k.
1.36 my 9900k instantly goes to 90s in cinebench
I get 5.0 across all cores at 1.35 on duel fan air with temps running into high 80's to low 90's or upper 70's to low 80's processing video right now...

Yes I am running a Gigabyte Auorus Z390 Ultra.
If You just delid and use liquid metal then you will just get 5c, but if you sand down the die by .2mm - .3mm you will get much more benefit. It is as if Intel made a built in performance improvement for the next gen by making the die too thick on purpose.
so can the i9 be clocked at over 5 GHz?
mines been at 5 for a while some have said it can do 5.4
Got 5.2 ghz with 1.35v stable with a 280mm aio hit 90 degrees
