[@radu1006]

What about low GPU tasks? Since you have flatten the curve, I get the feeling that you will have worse temp/power consumption in not so intensive tasks or idle.

[@TechIlliterate]

@@radu1006 From what I have observed the low power is still the same as before. Around 35W

[@Lock2002ful]

Holy shit, this is insane. Could you also recommend this for the 3080? Specifically something like the Gigabyte 3080 10GB Turbo? Cause that one runs hot and the fan explodes. I’d never have thought that this doesn’t affect performance negatively.

[@weirdodude1173]

I've been undervolting slightly, and it really is pretty sweet. Even just a small adjustment saves quite a bit of heat and power. Thumbs up.

[@DavidTMSN]

Is it pretty simple to do? I just got a 3080 ti from Asus (TUF OC) and was planning on replacing the thermal pads if it wasn't to expensive but this seems like a good alternative - possibly both.

I'm a computer technician and for years I've been telling people why they should undervolt the cpu and gpu. this video is perfect explain. My e2160 processor, released in 2006, had a speed of 1.8 GHz. I lowered the voltage with undervolt and took the speed to 3.0 GHz. It served perfectly, i gain more performance, better heats and still works. Undervolting extends the operating times of the devices. also, my rtx 3060 have a undervolt, same clock speed, was a hitting 78c before undervolt and now 50-60 around depends on the load. max 60.

[@Omegaxboy]

It's shocking how big different it makes for temp. I got an EVGA 3080ti ftw3 and It was hitting 83c all the time and started throttling and would even get hotter. The memory would sometimes go over 100c. I undervolted to .875 1875mhz seems to be very stable and played Days Gone for hours, and gpu temp never went above 69c and memory around low 80s. Room temp 75f.

[@ar1xx._.626]

I undervolted my 2070super and temp went from 83 to 67 degree with avg. 2-3 fps loss using Afterburner

[@shaofonger3917]

hey bro ! i am using zotac 2070Super and my temps are high on 1440p gaming (Borderlands 3 around 80c ? Valorant on low setting is on 70c) . As i am using Zotac card so i dled the Firework software but yeaaa i have no idea what i am doing but i would appreciate if i can get your MHz and Volt or maybe the % HAHA

[@henrycook859]

that analogy of the machine gun and thermal throttling is brilliant

[@AliShaikh_744]

Excellent video. Concise for the amount of information. You really nailed pretty much every advantage of undervolting

[@willboler830]

I'm going to spitball a reason why undervolting works without dong much lookup into the specifics and such. Digital comms works by looking for a 0 or -Vmax for "off" and Vmax for "on" (binary). Sometimes that's reversed, but that's not important. So as a chip designer, you can set thresholds for when we want a 0-bit and a 1-bit. Based on whatever these thresholds are and the voltage of the device, the settings of these thresholds and Vmax are defined in such a way to guarantee robust communications up to some probability of error under noise, power, and heat constraints. By changing the voltage of your device, you're tuning it to be closer to that threshold of failure while relying on less wattage to obtain the same digital values (the efficiency exploitation). Seeing how increased power usage can result in increased heat and reduced performance, getting it closer to that threshold will do the opposite by reducing power usage, reducing heat, and potentially increasing performance. But you're sacrificing stability in the long run by increasing the probability of occurrence of voltage threshold misclassifications. My guess is manufacturers release products with a CYA setting to ensure maximum robustness to heat and noise while allowing for room for tuners and power-users to define their own risk for their system and approach that threshold in such a fashion that no manufacturer would want to take responsibility for. It's probably also set based on some threshold of tolerance for manufacturer defects, where it's cheaper to just set all the chips to the same value without spending effort on tuning each device individually. So, depending on each system and user's risk tolerance, there's potential for increased performance and reduced power usage by undervolting, but the caveat is potential application failures due to misclassification of voltage signals, as you highlighted. But I didn't look any of this up, or any of the specific technologies involved that may help (such as error correction codes and such) so there's a bit more nuance to this.

[@ownage11445]

You earned a sub not just for the information but you explained heat by using BF1942 as an example

[@psychotic4560]

Wow - thanks for planning my weekend for me! This is amazing. Fingers crossed this works on my 2080ti!

[@psychotic4560]

Update: I managed to drop my gpu/mem temps by 3 degrees ea., my fans by 50% rpm and somehow actually increased my score by 200 points on 3dmark. Amazing. Thank you!

[@McFlyOrPie]

I appreciate this video soo much man! I have some Kryonaut Extreme and some thermal pads coming tomorrow for my 3080TI FE. (Plus I'm gonna cut a whole in the PSU, basement shroud, to mount a fan underneath to blow cool air right on the cooler.) I've had it since April and since I only paid $690USD thanks to Best Buy labeling it as an Open Box 3080 Non-TI FE. So I don't plan on replacing it with a 40s Series. I'll wait til 50s Series. But boy does she run hot! I managed a stable undervolt of 1950 at 925. It stays around 300 watts while getting the same FPS as stock. Now it runs SOOOO much cooler. 75% fan speed, (which is hard to hear in my case with an air purifier running nearby) 50-60C on the die and 69C (nice) on the VRAM not 70C+ on the die with 95C on the VRAM. I'm still doing the pads and paste. Figured I can get temps down more, and have thermal headroom if I need an overclock when newer games drop in the future.

[@CroIntr00X]

Mine msi gaming trio rtx 2080 with undervolt -lost 55mhz in boost 1960 to 1905 mhz -from 1.050mV to 0.912mV -shaved off 66W in max load -lost 10c in temps under load Works like a charm. Saved two profiles because in idle with undervolt its 30w and thats too much.

[@potatopope6637]

I love your videos, the quality matches channels with 10 times your amount of subscribers, nice job dude!

[@l.s.11]

I choose "ignorance is bliss" because I don't feel like tinkering. ;P Useful video tho!

[@Broformist]

Wow, interesting that you actually get increased performance. With my 3060 best I can do is maintain same performance as default settings while lowering power consumption by about 30 percent. Obviously that's still really nice.

[@adnanerochdi6982]

The one bad thing about UV is the increased probability of rendering artifacts and glitches.

[@Tarwada_]

This channel is criminally underrated!

[@sscultima]

this is exactly what i need to send to my buddy, keep telling him he needs to under volt

[@TechIlliterate]

Share it my dude!

[@ComeonmenID10T]

i have a similar system ( same CPU GPU & RAM ) and my Time Spy Score is 18024 , i did run it in 1440 P, have my card set to 821mV and 1880Hz clock, gives me a max of 69-71C

[@Duarteabe37]

Nice video!Did you notice increase gpu latency with the undervolt?

[@Silverhelm97]

Got my 3080ti running at 1800MHz and 800mV.

[@ARTEEX-ci9oc]

[@Kaiser187]

My 1080Ti dropped 15c on average in 1440p. Pretty shocked by the results.

[@River_Miles]

Undervolting brings the same quality of life improvements as kittay..

[@RUHappyATM]

I watched that other people who have AMD CPU/GPU laptops cannot use MSI AfterBurner or AMD Adrenalin software to under-volt or tune their laptops with recent Adrenalin software after v23.3.1. I wonder whether that's your opinion? I have a Dell 4800H/5600M combo and it's running hot, hot, hot. It's currently on the latest AMD driver, Adrenalin v24.something. The "curve editor" on Afterburner is not available for the 5600M dGPU, but it is available for the iGPU of the CPU 4800H. In Adrenalin, there's no tuning option for the 5600M dGPU. I'm getting really chezed off.

[@radu1006]

Looks like you can only gain performance if the card is not an OC edition. Otherwise only decreases the performance by about 2-3% and reduces the power and temp by a lot.

[@TXTRUSTUD]

Not being that guy but the bass in the audio on this video is distracting. My 2 cents would be to turn that down when editing the video...thx for the vid.

[@TechIlliterate]

No, Thank you very much! I tried a different mic for audio. I'll make sure to adjust it in the future. Thanks a lot!

[@TXTRUSTUD]

@@TXTRUSTUD I had that worry before I published it so I am happy someone confirmed it for me. Thanks again.

[@sarcof3459]

I wonder why the manufacturers and their technicians don't reduce the energy, I mean undervolt, if it's so good.

[@TechIlliterate]

Because they have to cover a wide range of chips. They may all have the same name but because of the silicon lottery they need to make sure the stock clocks work on all of them.

[@sarcof3459]

@@TechIlliterate I didn't think like that, thanks for the answer.

[@karthikr1237]

i dont find the video of how to undervolt using msi. can u please link the video on either description or on my comment

[@zaferheretic-ro5kc]

How I can undervolt for AMD

[@andrey.003]

Doesnt that curve editor actually mean underclock? Rather than undervolt? I am not a physics professor ofc but as far as i know lowering on Y axis taged FREQUENCY means for me lowering the clock. Not the voltage. On this graph to undervolt we need to move the points to the left wich maakes not sense here

[@tugrulserhat]

can't we just reduce power limit to like %80 instead of dealing with mhz and milivolts ? stuff we don't understand

[@TechIlliterate]

Yup! definitely can though you may end up with less than ideal results.

[@mr-vir2324]

using undervolt you can get lower powerdrain with same/higher perfomance only decreasing powerlimit you will definitely will have lower perfomance. so undervolt is need some time to build working profile, but for more time it give more profit and yeah, necroposting

[@randysalsman6992]

Nah. I'd rather overvolt, thermals or power be damned, pump up the frequency as far as I can get it and get those sweet sweet frames per second. The noise don't bother me because I game with headphones, plus when I game I always have put my gpu fans to the max anyhow.

[@avendorz]

i would totally do this, if i could undervolt the gpu in its bios. im not a fan of having some software opened in the background all the time and if its not running its not applied.

[@joniqst]

You can apply when windows starts, MSI afterburner doesn't need to be open

[@avendorz]

how would it apply, if msi afterburner wasnt opened?

[@joniqst]

@@avendorz there's an option within MSI afterburner to start with Windows. Maybe I'm wrong and it's just hidden but I don't see the app open in the taskbar until I actually go to open it when I need to and the settings are always applied. Even when open it uses negligible resources

[@maxwell1950]

Friend told me: try undervolting i was like ok search youtube click on your video and now i have 6 degrees cooler gpu with little if any performance drop. Why no1 told me sooner? rtx 2060

what kind of version of return to castle wolfenstein your using seem got new beach layout :P

It does look like that eh. BF 1942 was the only game I was sure had a cooldown bar haha

[@LNRivers]

What’s the best way to revert back to original stock voltage?

[@CroIntr00X]

Click revert icon in afterburner and save it. Or save 2 profiles in it. One stock one undervolt

[@ynwaynwa5629]

how to know if it's 'stable' or 'unstable' when u undervolt it?

[@TechIlliterate]

You'll know it's not stable if the application you're using crashes.

[@mr-vir2324]

i recommend use somewhat like msi kombuster for pre-test, then when you reach good stable results try it in heavy games or something, also you can get back about 10-15-30 mV for stability, it's your choice.

[@askariyaw]

Which video is your Msi Afterburner tutorial?

[@TechIlliterate]

I am working on it atm! Should be out in a couple days!

[@hoofarted4529]

Average FPS, curious what your lows look like. How are the drops on an under volt?

[@TechIlliterate]

Unfortunately I don't have that data. It appears that the FPS Min is nearly identical but undervolt max was 152 vs 145 of the stock. I might try using a different benchmark in the future to get a wider data set.

[@hoofarted4529]

@@TechIlliterate thanks for the response, I’m guessing that depending on your gpu results will vary so my best shot is probably just having a go myself. I’m new to fiddling with gpu clocks and voltages so thank you as well for the videos. 👍👍👍

[@Scizyr]

So the only thing undervolting does is lower temperature? I don't know it seems like a cop out from a properly cooled system. Wouldn't it be better to have good cooling on the GPU in order to have a higher stable clock frequency?

[@TechIlliterate]

Yeah if you want to! But there is always going to be a trade off. You could have the best cooled system but still get benefits from undervolting. Less power draw and less heat output into the room are good enough for me.

[@shawnpaulzuccarellorizzo]

I totally believe and can see everything you say is true. However, I don't find it to be worth my time to go through all the hassle of finding that particular sweet spot just to lower temps or reduce noise. I think it would be vastly important for someone having issues, but for those who understand system cooling, etc. it's just a hassle. I mean...how much money can you really be saving on that electricity bill? I feel the same way about overclocking too though...maximal effort for very minimal improvement. I digress though. I really enjoyed the video and the channel. you got a new sub.

[@ilhamazizi5564]

Is it okay for 3080 undervolt?

[@TechIlliterate]

Very similar settings

[@CroIntr00X]

Did someone checked idle gpu power consimption..i have saved 2 profiles in afterburner (stock and undervolt). Because with undervolt i have 30w idle gpu consimption, while on stock 3-10w. Can someone verify that?

[@hopey1809]

this guy even undervolted his beard

[@Z-add]

Is this applicable to laptops as well?

[@TechIlliterate]

Generally yes.

[@mr-vir2324]

for laptop is not recommended, is requirement, sacrifice 5-15% fps for silence, low temp and better battery life
