I'd definitely be interested in seeing an undervoltage guide for GPUs as well, I live in a very humid area and even on lower end hardware it still gets toasty, maybe a two parter, one for AMD and one for Nvidia
I underclock my GPU about 5% and it's just enough to keep it running silently and cool. I like it. I tell myself it lasts longer just to help justify it. LOL
i undervolt my gpu, and then overclock it a bit and i get a 18% boost in games vs stock
My 590 doesn't like to be undervolted. No matter what i try just doesn't like it.
@@lexwaldez you can actually get more performance while using less voltage and running cooler. There are some great guides out there. I have my 3070 running at 2025mhz @0.950v. Stock was around 1950mhz@1.07v
Optimum Tech has some great GPU and Ryzen undervolting guides, since he focuses on small form factor ITX builds where any thermal improvements are appreciated
After a lot of settings changes, I ended up undervolting my 5900X. It still boosts to normal speeds, but now stays under 75c rather than hitting 87c
What cooler do you have?
just last week I got a R9 5900x to replace a 3800x and I undervolted it and gained 400Mhz ALL core and my temps are cooler
I have my 5900x overclocked slightly and undervolted with an offset of -0.2, it benchmarks a few percentage higher (not too concerned about getting the best of the best) and runs substantially cooler.
With a Noctua D15s (and all my case fans at 40%) the highest I've seen it peak is 75°c (the joys of booting up) but in a render benchmark 63°c is more realistic and a 37/8°c idle.
@@mentholdeathray I have the vetroo v5. It's on the edge of it's ability to cool this, but it is what I got
I should also mention, as of right now, it has not gone above 65c for the entire day. During stress tests it will hit about 74 or so, but normal use it doesn't usually go past about 72
And here we are 2 years later when Intel is now releasing a patch to undervolt the CPUs b/c they're all failing! Jayz i just want to shout you out for this awesome advice! I followed this guide when I bought my 13700K and undervolted it by .08v - this video probably saved me $300 for a new CPU!
Have you checked HWiNFO if the undervolt causes WHEA problems? My undervolt didn't cause any troubles but it sure threw a lot of WHEA errors which you do not want to have.
His ending message of now having to do this with Intel chips lol. Aged like wine.
Thank you so much for the video. I did this on my 12600k and I’m much happier with the 10c drop for the 30 minute cinebench stress test. I would not have thought about doing this before your video.
I'm an electrical engineer and sometimes I need to be reminded of the value of undervolting. That being said this isn't always an option depending on cpu generation. I'm now motivated to attempt this on my 11700k. Thanks Jay, I'll have fun, but everyone using my PLEX library is going to feel the pain.
I have a 11700kf and it can do 120-140mv offset @ all core 5ghz and its worth it :)
Also worth mentioning cache frequency @ 4ghz is deal , 4.2 already needs waay more volts.
4ghz no adjustment base total cpuv ~1.30v
4.2 or 4.3ghz already wants to be base 1.42-1.47v
I could do a 50mV undervolt while running 20% oc on my core 2 back 13 years ago. Somethings never changed.
I have done it on a 10850k. -100 mV and instantly 12 degrees cooler and works like a charm
@@ungleich Whats your mobo? Mine is hitting 100 degrees under cinebench r15 on everything default.
i dont know if this will help you but if you have central air you can turn the fan on when gaming to help vent to room you are in to slow the heat up
Jay, VID is the voltage the CPU is requesting, Vcore is what is actually being sent to the CPU just to clear up the confusion.
A year ago an he has not even let you know. Sad 😔
I upgraded from a 95w CPU to this 241w 12900k and the temps are insane even on intel spec/defaults.
I went into BIOS and adjusted an offset of -0.150v and it decreased temps by 20 degrees C.
I thought that 241w would be okay as long as I dont OC, but firing up a game on stock settings and it's spiking to 90s. >_<
Thanks for this undervolt walkthrough...
No loss in performance on any workloads. I believe that reducing/increasing voltage away from defaults/stock will always introduce instability, however on my use case, I haven't encountered any.
Ty , i tried here with an off set of -0.130v using the same progam as the video, and temp drop from 100 to 82-79 in cinebench, test a bit in cod and it seems good, temp drop from avg 60 to avg 52 same perfomance , will test more in the week to see if it Crash or something.
I have i9 10850k cpu. Cine bench test is stable at 1.28v static. Anything below 1.25 crashes. How can find my offset voltage ? Once stable you save it as adaptive with negative offset ? Thanks I’m new to this.
What I did was leave the cpu core voltage to "Auto", then set the core voltage mode to "adaptive" with negative offset.
you can also "underclock" it from Power options on windows. From there Change advanced power settings> Processor power management> Maximum processor state and change it from 100 to 99. i think its basically the same as underclocking or volting idk could be wrong. Also do it at ur own risk, had it for 1 year on and no problems doe so its not risky or anything imo, just saw someone say its risky changing those kind of settings which i dont agree with. Simply revert if u have issues.
i'm glad you made an undervolting guide for 12th gen. I find undervolting is very useful for quite a few instances.
TLDR: it's great for thermal throttling, If breakers flip on the circuit under load, and keeping closed areas cooler.
One was my first gaming laptop was running really hot and starting to thermal throttle. Undervolting allowed it to stay cool and maintain turbo performance instead of throttling.
Last time, was when my latest build kept flipping a breaker under load. Actually both my desktops have UPS's bc breakers flip and interrupt what I'm doing and cause potential data corruption.
I have to undervolt my desktop, everytime people start running heaters to keep breakers from flipping.
It's helpful in hot weather to undervolt or turn down the power limit on your GPU in MSI Afterburner to keep it from pumping unnecessary heat into the room. (Same applies for CPU undervolt)
your tldr was longer than the stuff preceeding it. or is the tldr for the stuff coming after? dang i must be old.
more undervolting content guides etc please, also ever thought of using chapters on your videos?
Maybe the chapters didn't show up yet... idk
Chapters are SEVERELY underrated!
Why you need to use chapters on TH-cam videos
Also please give more info and tips on gaming laptops. I'm close to giving up after buying another and selling my 1 year old desktop.
Atm I'm questioning if i should return my leopard GP66 and stick with Lenovo legion 5 Pro. Or tbh just say fuck it and get a gaming desktop beast on sale (leopard was 700 USD off on sale) and then get a laptop in addition for bringing with me I guess. Tbh I just use my phone. But want a laptop keyboard. Ugh I give up. I can't even play games anymore. I spent most of my 60 hours in elden Ring trying to mod a d fix it. Fuck capitalism lol I'm so sick of products being made for profits instead of usage quality. Legion Pro 5 can't do 10 bpc with HDR 4k 120hz. Leopard fans are noisy. Nothing works. Or I guess ik just bad at choosing. The desktop I bought with a 3070 and r5 had terrible temps jfc what s shitty prebuild.
Chris feel free to post them. Look under wan show how it's done. Make yourself useful 😂.
But I agree chapters are sweet.
@@Venomonomonom commenting on this channel complaining about a prebuild lmao the irony
I love these cpu voltage related videos. You think you could one day do a video explaining all the different cpu voltages, what they are and what they do? Like the difference between VID and VCORE. And what voltages to adjust for what result. That would be awesome
There is not a huge amount of info out there on the two... But I believe Jay actually may have the interpretation of VID slightly wrong - I believe VID is what the cpu core is actually asking for, rather than the voltage being supplied, and VCORE is the actual voltage provided by the motherboard.
I've OC'd CPUs in the past, but never undervolted. Just upgraded from 11th to 13th Gen (i7-13700kf) and this is extremely helpful. Learned a lot from you! Thanks
Went from i9 9900k to 13700kf as well, holy moly, full custom water loop and went from 50 c under load to 80s. Undervolt is much needed!
@@aLumberingOx I no longer need to turn on the heat in my basement mancave while I'm in the flight simulator 😂
Im so late to this, but I got a 13700kf as well and it instantly goes for 100°C, did you undervolt?
@@groxincheck your cooler
@@kutemo3715 oh I changed it now.. its way cooler now
Hey, thanks Jay. I just built a 12900k system and was pretty surprised by the temps in Cinebench; up to 92 C on a 360 AIO. Need to try this.
That sorta sounds like a seating issue or paste?
Undervolted my 5600x from 4.6ghz 1.36v stock to 4.6ghz at 1.18v and took off about 15 degrees Celsius and allows me to run my pc quieter than before as fan curve is less aggressive. Only hits about 65 degrees max in cinebench r23 at roughly 80 watt power draw and 55 degrees while gaming.
No effect on fps right?
@@joaosantos5503 nope not at all
For a higher boost and much cooler cpu try running a negative PBO
seems a bit low but go off lol
I want to know how do you undervolt Ryzen. What software do you use?
This is so cool, I was part of the team that built XTU. Great video man!
Can you maybe explain why Watchdog won't work on Asus mobos like Z790-P - basically makes XTU unusable because it won't save settings on reboot.
I undervolted my R9 7950x to 1.035 V @ 4900 Mhz and lost less than 1% performance on Cinebench relative to Default. My temps dropped from 95 C to 62 C, and my power consumption dropped from 204 W to 138 W. Again, less than 1% performance impact.
That's fucking amazing. I'm definitely gonna try that with my new amd build as well.
Set a static voltage - about 1.3 volts or less, then use negative curve optimiser and the per core boost optimisation - you should gain more performance. In terms of temps, you can set the temp wall to 70 degrees c.
all cores @ 4900Mhz?
I've since changed OC strategies, since manual overclocks disables a lot of features such as PBO. I've shifted the voltage curve in PBO to get much better results without deactivating any features of the processor.
@@v0idbit69 did you do that in ryzen master, or is that something you can only access from bios?
Good to see someone addressing undervolting rather than overclocking. While I have overclocked some AMD APUs, I generally have no interest in overclocking, but reducing voltage/heat has many benefits, including allowing higher multi-core turbo speeds, lower operating and cooling costs, and less fan noise. Maybe more longevity too.
Would that mess with performance or anything?
@@MikeE_wf Generally, no, the typical point of undervolting is to lower the power/heat while maintaining the same clock speeds. However, there are instances where people have deliberate lowered clock speeds because they didn’t need maximum speed, only lower power/heat or longer battery life.
There are also cases, as with many of the older AMD K10 APUs where you could lower the voltage for idle clock speeds, while increasing the “non-boost” and “boost” clock speeds without raising the voltage (or even slightly lowering voltage), giving better performance with the same or less heat/power usage.
In short, there is a whole spectrum of things you can/could do. Newer CPUs give you much less control over these things.
@@MikeE_wf Not at all. If you go too low it'll only become unstable (freezes/BSOD). Otherwise there's no downsides at least for Intel systems.
@Ms Moon Boo Does this apply to older cpu's like the 6600k? as far as voltages go.
I've had my 6600k running at 4.5ghz OC for about 4-5 years now stable, but it's auto voltage hovering between 1.125-1.155v
reaches about low to mid 70's under load.
I second all of this, cooler chip, higher boost.
I have my 5900x overclocked slightly and undervolted with an offset of -0.2, it benchmarks a few percentage higher (not too concerned about getting the best of the best) and runs substantially cooler.
With a Noctua D15s (and all my case fans at 40%) the highest I've seen it peak is 75°c (the joys of booting up) but in a render benchmark 63°c is more realistic and a 37/8°c idle.
Curve Optimizer is the bees knees.
I undervolted my 5900x to just 1.2v and its at 4600mhz. . My temps is around 70c at the highest. Very impressed with Ryzen
D15 was able to handle a 5950X for me, I eventually got the parts for my water loop but while I was verifying my system stability it ran on a D15 and it still kept the CPU under control temp wise. Noctua really did their homework on that cooler.
@@filanfyretracker its not the best anymore
@@cement_slab They're supposed to be updating it but noctua works so slowly we'll be lucky if we see it on shelves early 2023
Every Intel PC I've built i have found default voltage on CPU to be unnecessarily high and find i often get better performance lowering it. I assume that the stock voltage is just a safe voltage for compatibility reasons, but with good parts you usually can lower it unless you're going with crazy overclocking. Good to see this is still fairly similar with newer generations too. I'm however thinking of going Zen4 with my next PC and it's been like 15-20 years since I built an AMD system. I'll likely do no OC'ing at first but curious how AMD differs these days when it comes to OC'ing and all.
100%
And now imagine how much you can undervolt if you drop the clock by maybe 200--300 MHz
AMD has pretty good auto OC, it's 95% better than most OCs (because the clocks can boost certain cores higher than an all core overclock)
Best way to get more performance on normal air coolers is normally undervolting, because lower temps -> cores can boost higher
A good video to watch on this is
*"PBO overclocking - absolutely worth it"*
yeah stock voltage is typically based on an average although intel's stock voltage is more varied based on die quality(?) while AMD just uses a hard number. for example 3k series was just a straight 1.35v for all cpu's(can't remember what 1k/2k series was anymore). with AMD there's zero reason to manually overclock.. just try to keep the temps as low as possible and let the cpu handle the rest.
The stock voltage has to be high enough to accommodate all wafer-to-wafer, chip-to-chip variance for the expected lifetime of those chips. Depending on silicon lottery, you may be able to get away with a 60mV under-volt today but need to reduce it to 40mV a few years down the road while another chip may only be able to get a 30mV under-volt out of the box.
After watching and implementing the video, went from 1.33 V on 13900K to 1.195 V. Temps dropped from 90+ C to around the 60+ C. Very impressive! Oh, I am on a Custom Look with EK. Yeah, 13th Gen is a challenge to cool, even on stock settings!
Hi. Can u please tell me what was the stock clock speed for i9 13900k ? Mine is always above 4.3 ghz at idle. Is it normal ?
Any differences in terms of gaming performance and fps count?
@@zubairhasan9246 if you keep your power plan option to ultimate performance in windows , this happens, switch it to power saver/ balanced when you are not using it to game and it gets down to 2.3 ghz
Not 100% sure, but in the video he is always using static voltages. My i9 13900k peaks up to 1.435. Did you just used static, or used the offset mode? If so, what value is the offset and is it just the difference between the max stock peak and the stable static voltage to be applied?
@@pietervandebroeck2021should I use static voltage? Wouldn't that be bad when I'm not inside a game vs when I am and it would use more power
would've been nice if you showed in the end how you translate the static voltage to an adaptive offset. you talked about it but didn't show it.
i undervolted both, cpu (12900k) and gpu (3080ti). Without undervolting the Temperatures, even with non benchmark programs, were too high for my liking. Now i'm happy. both dropped about 10°C
wow, that's incredible , i've never undervolted and i have a 12900K , ugh. i don't really know what to do because i hate messing with off the shelf Intel CPU chips. I have a 360mm Corsair Capellix using Lian Li fans (nice Lian Li Uni fans)...
@@harpoon_bakery162 easily got my 12600k to drop 10c on the hottest core if you do it in bios just subtract a bit at a time and do a cinebench run to make sure it's stable
@@chrisk3127 hmmm, that's intriguing for sure. i may have to tinker
@@harpoon_bakery162 "i don't really know what to do" you just watched a whole jayz video that gives you an idea WHAT TO DO..
@@harpoon_bakery162 It's very easy to undervolt, as Jay said. Just go into the BIOS and set the CPU voltage to -0.100 offset voltage for a start. Then run stabilty tests, put it -0.010V lower, rinse and repeat. I run my i7 7700K at -1.165 offset voltage absolutely stably with over -10c drop in temperature [can't remember exactly how much, think it was more].
Great video, this is exactly what I saw with my 12900K. Peak watt usage went down to 185W, and temps are now in the 75C range on R23 runs. 240AIO. Same issue with just bumping up a 100mhz though, but I haven't really explored bumping up volts again to overlock it, since CPU is so fast already, there is no need.
Biggest improvement to do for an Intel laptop. Those run crazy hot. I want to agree with you on the point that offset is better than static because it lets the system dynamically change. Just from experience with my Dell G5. Another thing, non-K series CPUs are not allowed to undervolt now, because of the security breach PlunderVolt, which is a shame tbh. I don't know if that is for laptops only but I highly doubt it.
Perhaps a ploy funded by intel Isræl make us buy the K variants more so. Would not be the first time! 💰 👃🏼 👥
I just replaced my G5 with a new computer because of this. Wish I saw this sooner.
@@sunram131 It was possible a few generations back. It is a Intel-wide issue sadly. Now I just run an old BIOS until I switch my computer. Glad you got something better now!
I was able to do it on my i7 10750h laptop. It made a significant difference. Brought temps down 10-13c with a -0.110V core voltage offset. Now I have a i7 12700k pc 4070 ti pc I built and the thing runs so cool I dont need an undervolt but I did a very mild Undervolt anyway at -0.075v. I can get it to -0.180v stable It's rediculous how cool my temps are when gaming and my performance. Cpu never goes above 50c under load and on idle is low 20s and my gpu tops out at 50c under load and idles around 28c. I have 1440p hdr 144hz monitor with freesync and I top out no issues in any game max settings and 144fps barely works my gpu and cpu. I couldnt be happier with my build and the air cooler I got for my cpu is just fantastic. Arctic Freezer Duo esports 34 cooler. That thing is a beast!
I have an i7-8850H. Does that mean everything I did in ThrottleStop isn't actually having an effect?
Would also love to see an under voltage guide. Fairly new to the game and a little nervous. My grandson and I love it though. Thanks as always for your great videos
Based grandpa 😎👍
uncle john
that's a really nice sampled CPU you got there, an amazing result dropping so many C's and V's and increasing you're whole systems health in the process, congrats
did the same thing with my 12600k dropped 10c on my hottest core performs basically the same
I actually keep my 5950x at 1.1V 4.3ghz and I did test it at one point with a little bit lower voltage at 4.4ghz and got to the point where in gaming/benchmarking at max it consumed 70-75 watts and I was pretty impressed but with the 1.1V it typically consumes less than 100 watts and never goes past at the extreme 73C on my air cooler. Great video Jay super informative 👍
By keeping your 5950x at that low level 1.1V 4.3Ghz which is great by the way if you are rendering all day long with Vray/Redshift/Arnold/etc. But if you are gaming? By default the CPU it's able to boost 2 cores at 4950-5000mhz. You just destroyed it for gaming purpose. Unless you have a Dark HERO motherboard which is able to switch overlocks. Then yes.
Would be nice if intel and amd came out with a "DL" lineup of pre-delidded cpus. Could make it easier to get better thermals of stuff...
You can deild your own as there are kits out there. I bought a full kit for my 4790K but turned out at the time I didn't need it.
I undervolt and overclock my 10700K with IntelETU and the results are amazing. -10ºC +0,2 Mhz all cores and -0,140V. Very happy with the end result.
I don't get it. 17min into vid, and still don't know what I "need" to do with my CPU "now". Just all a bunch of testing.

@@mistaboombosticyt No, thumbnails are clickbait and this one is no exception. He needs to stop yapping and create an actual undervolting guide.
@@calvin659he made one
What you need to do is undervolt your 12th gen CPU. You can do it using the same method he does here. Just keep in mind that your numbers may be different than his.
This reminds me of when I was trying to push my 6900xt. I OC'd Mhz & Ram, Cranked of Power Limit, & Turned up the fans. Got a very respectable Time Spy score but it was loud and hot. Finally hit reset & just started from scratch and undervolted, ended up dropping Mv down 75 and got nearly the exact same Time Spy score and dropped the Temps 10C. Lesson learned always undervolt first.
Although the CPU in this video is not the same as mine, makes it less relevant for me. However, the mutual explanation in every step taken is thoroughly substantiated and makes this one of the best tutorials of it's kind. It brought me many ' aha! ' moments. It's phenomenal the way Jay is able to cover and prevent common issues with each step staken by regular lads, with the few amount of words he uses in each step to do so. Good job!
My 13900ks actually runs BETTER undervolted at 1.3v, because now it does NOT thermal throttle anymore during Cinebench r23. And yes, the cooler is Arctic liquid freezer ii 420mm.
Crazy I was able to achieve similar results. Now my CPU runs about 15-20 degrees cooler than before.
I tested 12700k with undervolting and gained a few more points in cinebench AND It ran cooler about 12-15 degrees! Wild...
I want Jay to do a full core by core MAX underclock video.
And show us how much power and how much heat we are saving/removing.
The Static vs. Adaptive selection made a huge difference for my temps!
I'd love to see an updated guide for CPU undervolting. Intel 13th gen is still going crazy with the temperatures and there seems to be problems with Asus motherboards not supporting Watchdog which reverts unstable CPU configs to default after crashes. Also covering pros and cons of using XTU vs BIOS vs Throttle Stop.

FACTS! I've been undervolting since Optimum Tech came out with undervolting guides for Ryzen 5000 and graphics cards. Damn near the same performance, but cooler, quieter, and you'll pay less on your electrical bill; what's not to love?
I have was going to say the same thing. Optimum is great at undervolting.
On intel you don't lose performance. Sometimes gain. 5000 series has stupid logic that causes the CPU to down clockspeed slightly the more you undervolt. Still worth it in some cases like sff build with a 5900x or something but frustrating compared to intel.
You lose heating power for the winter.
I remember getting a Core 2 Duo CPU that was a mobile CPU but it was still socketed so I could use it in my desktop. I put a top end Swiftech cooler on it and after applying normal desktop voltage on that CPU it allowed me to get some really insane overclocks on it. It's too bad neither Intel nor AMD sells those mobile variants to end users.
@@coach- That is a false statement. If done correctly, with undervolting you can get that same or better performance than stock while using less energy and staying cooler. It's just fine tuning to match the voltage to your CPU or GPU. It also depends on the silicon quality of your chip. Some undervolt better than others. For instance my 3090 runs stock 1950 MHz @1.075v (using around 350w) but I undervolt it to .900v @ 1950 MHz (using around 275w) Or I can overclock it to 2050 MHz @ .975v (using around 300w) all while running cooler and using less power.
I did build my first pc one month ago following a lot of your videos and learned about stress testing and all that stuff. My i5 12600kf does not go above 55c at full load (not overclocked) in a 30 min Cinebench test, I'm really happy with it.
Are you using air or liquid cooling? I got a 12600k and I'm not sure what air cooler I want to use
@@Krushking99 im using a 360 aio water cooling kit from asus
@@hector-fpv ok :(
Nice video! This information could be helpful to a lot of folks. Undervolting earlier could have saved me $150. I went from a Dark Rock Pro 4 to a AIO 360 and also bought the Thermalright Intel12 generation CPU bending correction kit. I was astonished to see my temps were still getting up to ~95C and the CPU would periodically throttle during a Cinebench R23 loop. Using XTU to take .1 off of the core voltage worked flawlessly. Now the max my CPU P-Cores get to is ~79C and XTU never reports any thermal throttling during a 30 minute stability test of Cinebench R23.
I undervolted my 8086k and overclocked it. Got it down to 1.295v for a 5ghz all core oc. Managed to do 5.2ghz at 1.37v. That extra 100mhz like Jay says needs a ton more voltage for me. Didnt want to push it so far but undervolting was definitely worth it.
Thanks for posting. Been running my 8086k stock for years. Will try undervolting.
Do you use the cpu in a welding machine? I believe an overclocked 8086k should emit lots of heat at 5ghz (even if you use just a single core of it).
Do it with a 12th gen and single tower cooler next…I wanna see how much you can fine tune it in those circumstances, should be entertaining and exciting
I literally dropped like 18-20c on my 12700K and was able to do an incredibly quiet fan curve on my 3080 founders while still dropping a few degrees by undervolting. I'm glad you made a video about this; I feel like it's not talked about nearly enough by big creators.

Jay, thank you so much for this guide. With you help I was able to get my 12900K system down from 425-450 watts at load, ( with the fans just screaming ) to 300-285 watts under load. I had to take away some of the over clock ( I had to set to 5.5GHz ), but at 5 GHz the system still is awesome. ( and as an added bonus the radiator fans no longer spin up to loud levels ) I'm much happier with my system now, as power consumption is an issue for me. ( I run my system on solar / batteries, and now the system won't completely deplete my solar rack mount batteries overnight ) . Thanks again for a much needed guide. In an era where energy costs are going up daily, it was really nice to find a guide with a method to conserve some of my power.
Oh, almost forgot. My ASUS Hero Z690 motherboard had the voltage at 1.382. ( which was actually around 1.425 volts as measured with HW monitor ) I was able to get it down to 1.235. :-)
Offset voltage clocking is the absolute way forward. Combined with SpeedStep, I can save 5-10 degrees at AVX peak loads and way more on both temps and power consumption at average use or idle. And in these hot days with super expensive electricity tariffs, both are more important than ever. A little tricky (mostly frustrating in terms of the time and reboots involved) when dialing it in on some boards, but definitely worth it.
What do you do to speedstep?
Easiest is to disable load line calibration.
Videos like these are the main reason I love this channel so much, thanks for the tips and such great content.
Undervolting is the most amazing thing I discovered. I saw my 5900X getting warmer than I'd like with the air cooler, so I decided to give it a try. Lo and behold I must have won the silicon lottery because I was able to cut the voltage almost in half and still have the stability I needed. Now with a Noctua U12S and good airflow case I get high 50s/low 60s doing cinebench, which is the most stress I'll put my CPU under even when doing more programming related tasks
That's crazy. You got a good CPU for sure. But yea I'd say every CPU has quite a bit of headroom with lowering voltage. Most people still don't touch settings like that and having a pc crash because it needs a few mv more is definitely worse for the manufacturer than a bit more efficiency...
Undervoltage on i7 13700k with 1,175 V was stable in Cinebench but crashed with prime95. 1,250 is stable in cinebench and prime95. Yes Prime95 is an unrealistic use case but I like my Systems stable in every scenario.
I was spoiled with temperature sensors in the loop. Have a motherboard with one of those, base the fan speed off that, and you got a system where the fans can ramp up extremely slowly or even not at all since they focus on water temperature and not CPU temperature. Any one component, CPU or GPU(or anything else in the loop for that matter) can run to load and you never have to worry whether or not your fans are responding to the correct component.
7th gen Intel laptop, undervolting helped keep temps under 80°C peak. I average ~40°C after repasting under minimal load
I had to wipe my laptop and it installed a new BIOS that locks me out of under volting which fucking sucks because now I have to use Throttle Stop (which also won’t let me modify the voltage offset) to set my all core turbo to 3.2GHz and it’ll still reach 90c
@@anusmcgee4150 Thank the plundervolt vulnerability for that. Was nice being able to game on a passive cooled Surface Pro whilst still being able to touch it. Oh well...
@@anusmcgee4150 oh that sucks. I've been using ThrottleStop right from the start though, my laptop's BIOS is pretty basic
I think laptops in general just also generally sucks for finetuning like these. I wanted to tweak my C states to further decrease temps but haven't been able to. Just my naive and limited opinion
@@re.liable Did you try using older versions of XTU that fixed the issue for me
@@kkrox Haven't yet. I was using XTU before ThrottleStop and I didn't really like it
I am convinced, when you undervolt, The Temps Get Lower, But The score of Cinebench R23 also Get lower, much Lower, CMIIW.

Holy Hannah Jay. I’ve been struggling for over a month with a Gigabyte Aorus Z590 Pro AX and an 11600k. Could’t control temps or voltages on this board. It was almost like the board was ignoring me. Very, very frustrating experience with this Gigabyte bios, and yes, the latest. Finally gave up using the bios and instead chose to use XTU. Finally I have control over voltage and temps. I don’t know what I missed in the Gigabyte bios, but at one point the board was throwing over 1.6v into the 11600k. Performance was dismal. Using XTU SOLVED THE PROBLEM. I am still using adaptive voltage, but have undervolted by 200mv in order to get the voltage I desired (1.26 to 1.28 under 100% load)
Have the same problem with my i9 13900k. It throttles when testing with Aida on stock settings. I think these cpus getting this hot is the new normal!
That's a big problem.
Just disable load line calibration or set it to the minimum. On Asus board, it's level 1. You will see lower temps without compromising stability since at stock settings LLC is redundant.
Been wondering what to do with that
LLC is dependant on CPU/settings. For example (under my understanding) lets say you have a 5Ghz CPU and you run a stress test with 1.45 volts set in the bios. If your voltage readout during the stress test is under/over what you set in the bios, you can then adjust the level of LLC. What youre wanting to do here is to have as close of a value on desktop with load, as what you set via the BIOS.
@@shadowxsm would you use say prime95 small batch to get the voltage readout at load?
I have my I9-13900k undervolted to 0.0625, here are my results:
Pre-Voltage Change:
100C in Cinebench after 30 minutes even with a deepcool lt720, r23 score of about 39400.
Post Voltage Change:
84C max in Cinebench after 30 minutes, r23 score of about 40730.
Better performance because Im not hitting thermal throttling.
Able to now run my system at 5.8ghz no problem
I think I’m finally switching to Intel after all of these years lol I just def need to remember to do a slight UV
I decided to undervolt my i7-8700k, with a evga gtx960 2gb gpu, about a month or two ago when my energy company decided to start charging stupid amounts of money for electric, even though they can check up on actual usage with my meter in virtual real time. atm got my pc to averaging 69-85 watts from the wall depending on work load, but normal use is 69 watts, as far as going further with it, then I haven't tried dropping the voltage, as every time I have tried playing with it, then the system just keeps shutting down.but got a decent speed for computer not using too much power as long as not playing a modern game. and works how it is supposed to, so thinking of just leaving it at the current settings.
I have done this for ages for my Ryzen 5 5600X - essentially disabling boost and running the default core clock (3.7GHz). Then I undervolted and I ran at at 0.78V. Essentially never more than 33C when 100% utilised (Noctua NH-D15, fans at 20-30%).
EDIT: This is alsk a very good idea for someone looking for a media station or such - just pop in like a 2060 and underclock and you can pretty much run it all with an SFX 300W PSU if you so desire. Very easy and efficient to run for ages
yes that works for temps but you lose a lot of performance
@@welshinu It's comparable to like a 2700x operating normally. But in general for compact builds it's a good idea.
@@marcelbarlik729 if your using it for a compact build then happy days but i would have gone for a cpu more suited for a compact build i want the most i can get out of a cpu oc and uv with little to no lose in performance ( preferably a gain 😁)
Perfect time for this video, with the summer aproching it's starting to get very hot (in my region some days the temperature can touch 45-50°) and I heard that undervolting would be a nice solution!
Just last week I undervolted a Ryzen 5800x that was getting too hot for a customer (92C+). Prebuilt gaming PC used for streaming, the case was small with a cheap air cooler and no mounts for an AIO. Apex still ran at her locked 200fps with no quality loss on stream. So this isn't just an Intel thing.
I just rebuilt my pc with a 13700K and msi motherboard and was seeing outrageous temps between 80c - 100c under load. I thought this was me not putting things together correctly but I didn’t know about this insane wattage draw. I do a lot of after effects which demands heavy cpu use and the last thing I want is to fry my brand new chip. Gonna install this now and dial it in. Thank you.
Is this video more than 2 years old? How did you get around the plundervolt bios lock on undervolting?
I just put a 13700k in today. Gonna give undervolting a try for the first time! Thanks for the vid!
let me know i got the same chip building as we speak
@@Lee-gm7zi it’s gonna be a minute. I’m going to have to do the thermal paste again. I was in a bit of a hurry and I think I botched it, these temps are a bit higher than it seems like it should be.
@@justinward3218 I installed a 13700k in ASUS Z690 2 days ago, had to install a 12th gen Celeron for it to post the i7 after BIOS update. My temps are fine unless I load it up. I peg at 100c in Cinebench all core test, the i7 doesn't fail and HWmonitor says there was NO thermal or power throttling. It was pulling 5.2-5.3Ghz the whole time at 100c on P cores! LOL I watched the whole 9 minute test at 99-100c all P cores, it was terrifying, the aio fans were spinning so fast they sounded like they were going to lift off. The E cores stayed around 86c. But the P cores stayed 99-100c from like 2 seconds in until the end. The i7 scored 30051 and it didn't crash, which is almost dead on spec. I have tried numerous games and the CPU stays around 65c same as my ASUS 3080 at about 65c. So my cooler (ASUS RYUO 240) and thermal paste is doing fine. It only heats up on all core loads. I am hearing MCE might be the issue and undervolting is the way. I am still investigating but saw your post and figured two heads is better than one. LOL
@@auntiepha8343 I’m idling about 40C and hitting 70C at about 30% load in Overwatch. Nothing dangerous but higher than it should be. Since it’s not super urgent, I’m going to let it be for the moment while I wait on my thermal paste shipment from Newegg. I looked and looked but couldn’t find my backup tube.
I have high hopes that reapplication will be the solution since, as I mentioned, I did the job in a rush and didn’t bother being careful torquing down the heat plate for my pump. I’m running a 360 rad Corsair AIO, and getting expected readings from it except that the fluid is significantly cooler (27-30C at idle)than the chip, again pointing to poor contact being the problem.
@@justinward3218 I think the chip just runs hot, I don't think it's your paste. Let me know how it turns out. I used Corsair TM30 once and MX-4 paste once both with the ASUS Ryuo 240 AIO, same results. My idle is in the mid to low 30's and gaming mid to high 60's. The only time my 13700k gets hot (100c) is in Cinebench. Time Spy, Firestrike and Heaven my temps are high 60's low 70's. honestly if I hadn't checked the temperature on Cinebench I wouldn't have known it was anywhere near 100c because it didn't throttle the performance even though it pegged 100c the entire test. I scored 30051 which is fine for a 13700k on Cinebench. If the cooler wasn't working right I think the chip would have throttled. It wants to be hot. I limited my Delta T to 90 degrees in BIOS. The CPU pegged 90c on cinebench and scored 29885, lower than the 100c score. I set BIOS to enforce all limits on the CPU and it still pegged 100c in cinebench and scored 29974. No throttles at 100c or 90c. My CPU is within a couple degrees of my 3080 when gaming so I am siding on the chip just being a furnace. I am interested in what you find out in your deep dive though, update here if you get a chance. Good luck Justin.
Thank you very much for this video, I use an i9 10900k water cooled, my temps would reach upper 90's and 100's then would throttle when playing BF 2042 or UBoat. I followed your video and undervolted - 0.150, ran the games and temps have dropped to no higher than 75's, brilliant.. ive since had to readjust to -0.100 because would crash after 30 mins or so of gaming ,this has solved it and now runs perfectly and 75's temps.. Thanks you JayzTwoCents.
I see what everyone is saying now. I just undervolted my Core i7-5600U on my ThinkPad T450s, and hoo mama! The thermal readings I got under load and on idle *SMASHED* my previous record. Idle was in the mid to low 30's (Celsius), and load was mid to high 40's!
For Linux, I used intel-undervolt to decrease power draw on both cores and the GPU by -70 millivolts (mV) and TLP to cap maximum CPU usage at 60%, with 12% being the minimum.
We are all aware of the 12900k heat and power draw creating the situation for undervolting. Your thoughts on doing the same with 12700k, 12600k, 12400, 12100? Bonus for when working with chipsets H670, B660, 610, ect
Also curious, also screw TH-cam commenter bots

my i3 12100F stays super cool with just the stock cooler
@@chrisk3127 12600k on custom loop, 5.1 all P-Cores 4.0 all E-Cores, 1.19v and 74C on Cinebench, pulling 154W
Doesn't make sense for the 12600K or below since they don't draw anywhere near enough power to overwhelm a decent 240mm aio or dual tower air cooler. But if someone wants to run in an it's build with small coolers or want to run fans slightly slower for quietness then sure they could do it
You should make a video showing how all motherboards run different voltages on the same chip.
if you go on the voltage offset and have it set to let your cpu idle down be warned normally the idle voltage will run into issues before the load voltage
best video I've seen on the subject while researching ways to keep my power-hungry i7-13700K under throttle limits. thank you for the upload and excellent explanations
Outstanding test!! I wonder why Intel doesn’t handle the voltage and drop it to mitigate the high temps the 12900 generates?
My understanding is that individually tuning chips is just not practical at scale. So instead Intel picks one voltage and sets every 12900 to that, knowing that they'll function fine on it. Most chips can work below that, but not all will handle a certain voltage and working out what the lowest possible voltage is is time consuming.
Jay you need to update this video. undervolting is gone now. it was disabled due to "security" patch. load of horse crap. any solutions we have to problems are "vulnerabilities"

The alliteration in that sponsor though. Custom Coiled Keyboard Cables. I love it.

Been undervolting for literally every build years now it helps so much. Always start with undervolt then work from there. Right now currently got two setups. One is my Alienware 51m-R2 w/10700k running 5.2 all core and temps are usually 65c while gaming COD,PUBG, BFV(runs a little hotter) with jumps to 75c but never over. Which i am super impressed with, being a laptop and all. Same goes for gpu 2080 Super never sees over 75c, +150core +1000mem(lil bit of silicone lottery going on, as mine is 2nd highest score on userbenchmark). Has no problem running 27" 1440p/270hz monitor pushing around 200fps. My desktop build is a generation older a 9900k/2080ti and performs pretty much the same with a 5ghz all core overclock(280mm aio and few extra fans). Undervolting is key!

These 'adjusting this setting has this effect' type of videos are much better than seeing someone did an extreme overclock without knowing how they get to the settings they did. I have put overclocking features to use on systems more to downgrade a system as a way to buy time on a dying system than I have on overclocking it for better performance but knowing what impacts what is more important to make it easier than trial+error.
Would LOVE to see which services we can disable!!! Please like! :D
With MSI motherboards you could also try the CPU Lite load setting. Lowering this value make CPU use less power. Saw some youtube videos (serach for CPU Lite load MSI) with amazing results. Still need to test for stability similar to normal undervolting. Lowering it too much may cause unstability.
Thanks for reminding me about Clock Tuner for Ryzen. I hadn't played with it since 2.0 came out with Zen 2 support. With some small configurations in BIOS, it set the core frequencies and voltages for the most efficient and optimal use. It basically does it all for you, which is very convenient for people that just want to set it and forget it. My 5800x is almost 1000 points better at Cinebench R23's multi-core load (4.65Ghz), and is 13c cooler (67c down from 81c) on a 1.25mV undervolt.
Where can I find clock tuner for Ryzen? Do you know if it helps first gen Ryzen?
I run my 5800x @ 4.6Ghz @ 1.15v
You could run it much lower volts if you dropped it down to 4.6Ghz.
Don't base your overclock or underclock using cinebench because it doesn't use turbo boost clock speeds
2:37 no, thicker block won't help, what we need is either bigger die (won't happen) or direct die contact, a thicker block will make it even more difficult to move the heat away
Agreed!
My 1070 STRIX runs at 1911MHz, 912mV and draws 110-125W under load thanks to UV.
My Ryzen 3100 can do 1.12V with +200MHz, making it a 45W chip
Just turning the dials a liiiitle bit down can make a big diff because everything is being pushed to the limit
16:48 exactly. I've seen Zen 2 Ryzen being fed everything from 1.2 to 1.45!!!V with default settings
my 5900 seems to like going straight to 1.45

@@ass5kickin i used the bios, but there could be other programs for it.
@@ass5kickin BIOS, go to PBO and press from auto to advanced and you see the curve optimizer. Then you put the magnitude to negative and do it from there, use OCCT and test everytime you change the magnitude from -5, -10, -15, -20,-- 25, -30. Until you see OCCT says error, then you just bump back the magnitude by one and keep checking for instability.
@@ass5kickin first with Ryzen Master, then permanently in the UEFI
Hi Jay, you mentioned that your CPU power draw fell to around 200W after a rather long iteration to find a stable negativ offset level for your CPU. How much do you gain with the 12900K in CPU benchmarks compared to the method of just limiting PL2 and PL1 in BIOS to 200W? A very fast and easy way to bring CPU temps down.
@Ms Moon Boo beleive your doing it wrong if your losing speed undervolting....i gained 100 mhz across the board just with the pbo co
@Ms Moon Boo experience says otherwise
I used PBO2 on my 5600x with a -30 negative offset to undervolt (thanks to Optimum Tech!)
If there's dynamic vcore in place I don't trust any of these results.
Geez! I now know more than I ever did before about undervolting. Great video, great tutorial, and I will be putting some of this to use trying to get my i9-10900k to run cooler.
Hi Jay. Yes I agree. I have WORLD RECORD using OCCT for speed of Intel 10900k at 5.3ghz all core for avx and 5.5ghz all core sse. Under-volting really helped.

I know this is not a high end pc BUT, Running Lenovo L340 I7 - 9750H Ideapad Stock immediately thermal throttled when gaming. Undervolted CPU -126mV immediately dropped the temp. Overclocked the GTX1650 mobile from 4000mhz to 4558mhz memory clock and and boosted the core clock by +196mhz and now my laptop wont thermal throttle at all with a boost of FPS. Stock, it thermal throttle and cut my CPU to 2600mhz and got a solid 78 FPS sitting at 90 plus degrees. Now my CPU sits at 4067mhz at 76 degrees and my GPU is at 66-71 degrees with fps 108 fps average in PUBG. Very happy with the small mod for such big gains.

edit: Althought my volatge is set to static at 1.185 the actual reading from HW-Info is 1.225-1.23v when running Cinebench.
Thank you for this. I was so confused because I built a 12th gen i7 machine and in cinebench23 I was hitting 100c… I have a beefy air cooler, and great fans, and great airflow in general. Thought I mounted things wrong, but everything was perfect. Un did and remounted the cooler a bunch with no changes in temps. I’ll mess with this, and I’ll be happy with low 80s under this kind of load
So, what about undervolting Ryzen? I've been experimenting with undervolting, but I always end up killing my performance because of it. I'd really like a basic tutorial about voltage and frequency manipulation on both CPUs and GPUs.
Nicely shows how far you can dial in a individual processor. They really need robust factory settings, but unfortunately it comes at the expense of power.
Engineer POV: I caught on to undervolting a long time ago. It makes sense and it works; cooler operation with little or no loss in performance.
Overclocking only makes sense as a sport for people who care about benchmarks and don't mind replacing parts that die prematurely.
Undervolting is efficient yeah. I undervolted my 5700xt sapphire nitro from stock 1.2v to 1.07v. I did drop the core by 100mhz but bumped up the memory by 80mhz and the performance was roughly the same but it runs so cool and quiet its really nice. Especially in the summer when the room is hot even without pc pushing out heat when running games.
Love you Jay, keep up the great videos! You inspired me to get into water cooling.
Others may need to make alternative adjustments dependent upon there coolers & skills to cool their systems.
