Thank you, even though the video is short I still had to take the time to make sure everything was stable especially since its my first time doing this. I think I got good results so I appreciate that you made this video for the community.
Thank you for explaining this so well.
Thank you so much! Completely stock, my GPU would jump between 1935MHz and 1920MHz so I chose 1935 as my frequency. I was able to drop my voltage by 100mV, which after checking my PC plugged into my Killowatt meter, that reduced my system wide consumption during the benchmark by 50W! Now onto CPU undervolting!
Amazing! Thank you for showing this, gained a sub. I'm currently stuck using a small form factor PC until my parts come for the new one. The 2080 super in it gets a bit too warm and loud.
Original:
Temp: 74c
Clock Speed: 1700mhz
Power: 850-900mv
After this:
Temp: 63c
Clock Speed: 1785mhz
Power: 800mv
So not only did this help keep everything cooler, I was also able to increase clock speeds due to the lower heat and still shave off some voltage. Will certainly be doing this on the new computer going forward.
Seriously best Undervolt video on CZcams. Thank you!
Thanks Smokey 🔥
Hi tech dweeb your videos are really interesting and fun to watch i am loving them ❤️
Thanks buddy!
Wow!!! Thank you so much!!! Dropped my GPU Temps by 20°C with no performance loss!!!!
Though it's a bit different with an AMD card. Would be nice if you could do a video about that too in the future.
Thanks for the suggestion! I just might.
No comment you are a real artist
Such a good video, the fans on my 3070 Ti would go so fast I can hear them start rattling a little. Went from ~54 fps to ~51 fps in RDR2 and my fans slowed down just enough so that the rattling sound is gone. Thank you!
Glad it helped you out!
This is probably the best underclocking tutorial on youtube.
I can see until now , only you are the one who actually made a clip guilding undervolt nvidia gpu ! Greatjob my man !☆
I'm surprised more people don't talk about undervolting!
My MSI 3060 Ti VENTUS 2X doesn't have the best of coolers. Your guide dropped temps down from 70 - 66, and power draw from 200w to 166W. Did 825mV, 1700mhz clock undervolt after find ing results on MSI Kombustor. Happy with the reduced noise, heat and power draw.
Woah! It’s like magic 🪄 my RTX4060 was running at 70°C all the time on 4K gaming
Original:
Temp: 70°C
Clock speed: 2600MHz
Voltage: 1000mV
Fan Speed: 56%
FPS: 58
After:
Temp: 66°C
Clock Speed: 2595Mhz
Voltage: 925mV
Fan Speed: 32%
FPS: 60
I gained 2 FPS 😂. I probably could’ve gone lower but I got too excited and booted up dead space to try it out. It’s running so good and a lot quieter! Thank you for this! 🍻
Great video! I love your voice so much too 👍
Great video!!! My room was getting toasty and wanted to drop the power draw haha!
Original:
Temp: 63c
Clock Speed: 1835mhz
Power: 1028mv
After this:
Temp: 58c
Clock Speed: 1890mhz
Power: 900mv
I lowered my power draw by 50 watts then added a small overclock and gained 2 fps in game. This is awesome.
First of all, thank you for a spot-on and no bullshit tutorial. I spent a few hours doing some in-depth testing with this, and got some pretty cool results i would like to share.
I have a Gigabyte RTX 3070 Eagle OC. It is advertised to have a core clock of 1770 MHz (1725MHz reference card).
I started by running the Kombustor for a whole 20 minutes just to have a lot heat generate inside the pc. Results after 20min:
GPU temperature: 79 celcius (when i play RDR2 i get 82 celsius after a while).
Fan speed: 90%
GPU core clock: 1725 MHz (got up to 1770 MHz in the beginning but declined after 8 minutes).
Volt: 918 mV (got up to about 950 but settled at 918 after 10 minutes).
FPS: 89-92
So i was getting less clockspeed than advertised (1725 vs 1770) while the GPU got a little too hot for my taste.
I tried different settings, and finally i put coreclock to 1770 MHz (as advertised) and reduced Volt to 825 mV.
Ran the Kombustor for another 20 minutes and got the following result:
GPU temp: 71 degrees (8 degrees decline)
Fan speed: 79% (11 points decline)
GPU coreclock: 1800 MHz (75 MHz increase, dont know why it gave me 1800 when i set it to 1770, but whatever)
FPS: 90-93 (1 FPS increase)
I ran Kombustor one more time for 10 mins on same settings just to verify, and got just about the same results (15 less MHz).
To conclude, i now have 8 celcius cooler card with a slight performance increase. The card is now performing BETTER while generating less heat and noise. Im very happy.
Havent stress-tested it in RDR2 yet, if it crashes i will just increase volt with 25 mV up to 850 mV and should be good.
Again, thank you for a great tutorial.
Amazing results! I love seeing this!
Great tutorial.
I nerd do it because my Quadro T600 runs hotter than hell into a SFF Optiplex 3060.
Thanks a lot!
I'm not sure if you can do it on a T600, they might have the voltages locked down on that GPU :/
You forgot one main thing: simultaneously you save power - that is $$$
Dude thank you. This stuffs a lil overwhelming
Omg thank you so much bro. My results are insane. I have a rtx 3060. It went from 82 degrees to 67 and the fps from 58 to 54. Its so worth it.
Niiiiiiice! Glad I could help :)
You forgot to tell ppl that undervolt done unproperlly it is like OC at stock speeds. It is more beneficial for stock speeds but it will degrade like OC the silicon. Indeed that degrade is minimal if done properlly in both cases and also it takes a lot of time in case of gpu silicon. The degrade is faster on memory silicon, so there it should be left at stocks or clocks also lowered if voltage is low. Another safe "undervolt" is limiting the power with -10/-15% from afterburner and the video card bios will also lower the clock speed acordentlly, usually in games you lose very little fps (1-3) but lower power consumption and also it is safer for the video card. So in games where fps is not a problem, this way is better in my opinion for the hardware. Cheers!
What is the difference between a proper and improper undervolt?
@@alrightfritz9692 artefacts/crash/black screen. If done properly you will not have this issues.
From what I understand, Kombuster doesn't use ray tracing. Which makes sense because after I first UV'd, my heavier RT games would keep crashing. I downloaded a free benchmark that includes RT and was able to undervolt my 3060ti by only 75 mV after that. Haven't been able to try it in combo with DLSS, but that's more work and finangling than I'm willing to do.
Good to know!
thanks!!!!!
Thank you
I see some videos put the -250 or whatever number I to the core clock and some don’t is there a reason ?
You are so funny😂
Great Video 👍👍
Thanks buddy :D
thank you for the tutorial, I got 0.600mV to 0.700mV at 1440Mhz with 40-60W power consumption playing Dirt Rally 2.0 with Fps 120s FPS, but it was very slow dropping frames below 50fps in PES 2024. Finally I made a 2nd profile with 0.600 mV up to 0.800mV at 1500Mhz with 40-80W quite powerful power consumption, finally you can get 55FPS at the goal moment and when playing at full 60FPS
i started thinkering with OC/UV a couple months ago and managed to get my RX570 to 1400Mhz@1065mV.
Great idea! I got -125mV/-10°C on my 3060ti! 🤩
Nice results!
Hey I was wondering if you could test VR on the rx 6400 if you have a headset of course.
Nah I don't have a headset, but I've been thinking about getting one 🤔
In small cases (mid towers) the EVGA 3090 XC3 ULTRA is the way to go but they are noisy (I don't care about OC), will this do the job or am I wasting my time with that model of gpu?
This definitely helps with the noise. I have no idea about your situation but it is a huge help with the two higher-end gpus that I own 3080 & 6700 xt)
Can you tell which one will give better fps i3 10100f with t400 or ryzen 5600g
My clock speed keeps changing by itself during games, its extremely annoying. Automatic tuning is disabled in the nvidia performance overlay. What do I do?
Nice 2DS, I have N2DSXL and retroarch on it
This i goona try on my Asus RX 580 Dual Oc edition.
It sounds like a jet engine when it reaches 72-74 deggres
After undervolting can’t you then manually increase the speed of the fans to cool the gpu even more than just undervolting? I use a razor laptop which I manually set the fan speed at 5500 rpm when gaming, so can’t I undervolt and keep that high speed to cool my gpu as much as possible?
True, but that increases noise. Half the reason I undervolt in the first place is to keep the noise down.
Did u forgot to mention that gpu draws much less power after undervolting or i just overheard it? And u can do it on notebook too and there is where real magic starts!
Yeah I didn't mention that. I dunno why, I probably should have. It's not much of an energy savings on desktop but you're totally right that on laptops it can save a ton of battery.
i have gtx 760 and he crashed always when enter a game but on desktop no problem just when i run some games crashed and black screen monitor i have a very low psw its garbage 450w i dont think is 450w for real i want to undervolting gpu but when i open msi afterburner i activated voltage control but the curve editor not showing any solution
Can you make a under volt for CPU ?
I knocked my GTX 1660Ti down from 975mv to 825mv.... big drop in fan speed and temp and I only use it for Zwift and it's still cracking out 60fps at Ultra/4K on the 4K tv....hopefully prolong the life of the card if nothing else (I tried 800mv and it crashed...also no benefit to adding any memory OC for me just ran hotter moving from 6000Mhz to 6500Mhz as other you tubers have advised and no increase in fps on Kombustor)
hello! can you make a video about emulators for noentiendo witch? xD
bro i have a question. :| do i need to update b610/b660 bios to get the resizable bar option ( for 10 and 11 gen update requires i think)and i have a 3060 gpu ..... do i need to update the vbios ....? of 3060? (:/)
i haven't checked the option in the bios yet .
is this option available for newer gen models(without a bios or sbios update)? .
I'm asking because arc a380 requires resizable bar and . :/ i don't wanna mess with bios because in here we get electricity supply cut . (more than usual now days ) so i don't wanna stay at risk. :|
If it's running fine now you don't NEED reBar to be enabled, it's a small bump in performance though so it's worth it IMO. Your b610/b660 should have reBar in the bios already (those boards shipped after resizable bar was a thing). If not you can update the bios for sure. No harm in updating the bios, it's good practice to have the latest bios. Same with the vbios of the GPU - if it's a first gen 3060 it might not have reBar support. You can check in a program like GpuZ if reBar is currently enabled and your GPU is using it.
:| thank u so much i don't need it for my 3060 but I'm going to use it for arc a380 (arc a380 without resizable bar performance is horrible just like 6500 xt with pcie gen 3 ) . i think arc a380 ll not require vbios update to run resizable bar and . :| yup i have my 2nd pc which has asus prime h610 with a 12100 processor. :) i ll buy an arc a380 just to enhance the performance . anyway the info is so helpful.
thank you.
Im new to this:
What about the lowering of the core at the beginning of the tutorial? Don't we have to raise the core again? (I've put -220)
Yeah, we lower it, and then raise it only to the point we need it to be (at 03:40), so we don't let the core go higher than it needs to, but at a lower voltage.
@@TechDweeb thank you! Clearly I missed something in the video lol, sorry
Wouldn’t lowering the core clock (-250) reduce performance for older games or capping frame rates since it’s at a lower clock speed than before?
Lowering the core clock is only temporary, the goal is to get the GPU running at approximately the same clock it was before, but at a lower voltage. The first step is lowering the clock globally, then raising the clock back up to where you want it but at a lower voltage.
@@TechDweebhe is talking about when your gpu is not at a full load so it drops clocks/voltage to save power, basically because of the way you UV in this video when it uses a lower voltage the clock is lower at that set voltage, you want to try keep the same curve when UVing so at lower voltages you don't have that massive drop off in clock speed
does msi afterburner have to be open to apply the undervolt , or it's applied no matter what
Yes it does need to be open. I have mine start with windows and it just runs in the background.
@@TechDweeb same from now on
Just got my new rtx 2060s and went from 950mV/79° to 850mV/69°, as for the fans went from 78% to 68% usage, tried to go lower but the Kombustor and my games kept crashing, so i guess this is my magical number, and i hope this will be of help to anyone who has the same gpu as me.
my voltage is saying 0 on msi afterburner.
@@itchy2366 go to settings and unlock voltage monitoring, it was shown in the video.
if any one is curious lol a 4090 gaming x trio lowest it would go or i could take it to with a base clock of 2740 a casual 300 wats @2740 mhz @1050 on mem lowest at 925mV lol reduces temps on high stress test down to a casual 47c XD wild and i am running it in a mini atx case and i gained +10% over stock and -30% on oc @2955 mhz and mem @1150 440 wats at 63c idk how to feel tbh lol never undervolted before but i tried it and the results for me for this case i feel over clocking is my prefrence i have a 1000w psu and dont mind fan noise at all granted i wear a headset for everything and rarely use a speaker so this is the data i got if you can do better for sure let me know :D id love to see who can undervolt harder then this on a gaming x trio
I think the biggest thing I’m confused about is my clock speed is always changing it never settles so I don’t know what it’s supposed to be
Lower the voltage 25mv and test the games not the stress test because is not the same
I'm gonna like the video before I even watch it. That's how much of a real G I am.
👆 Certified G right here
hi, i dont know what im doing wrong, but i cant get the gpu voltage meter to read anything?
That may mean that your card does not allow voltage control, so this won't work for you.
Totally off topic, but what does overclocking ram do? Great video once again :)
Attempt to make it run faster. By feeding it more power to reduce the latency and which it handle data with the end goal of trying to reduce clock timings.
Pretty much the same thing as overclocking a CPU or GPU. You're just getting the clock cycles to run faster. The difference for ram is that it's MADE to be overclocked. That's what XMP profiles are for, they are the factory overclocks that you can select to automatically increase the clock speed on your ram. And if you know what you're doing (I barely do tbh), you can overclock it manually to go beyond spec.
@@TechDweeb Makes sense, thank you :)
I am using an AMD Adrenalin... so after I watched this. I tried manually undervolting without tweaking the frequency.
Did I do it right?
There are 3 points there for example (the numbers are samples only)
1 - The lowest point = 800
2 - The mid point = 950
3 - The Highest point = 1850
I tried reducing it by 25, and this is what I do...
1 = 800 minus 25
2 = 950 minus 25
3 = 1850 minus 25
Did I do it right? I just follow the concept on your window.
Why use adrenalin? It is native software I think it wouldn't mess up my GPU because it's made by AMD. BTW I'm using MSI Mech RX 5500 XT 8GB OC
Great video BTW. Easy to follow.
Yeah the way you do it in adrenaline is you just need to reduce the 'voltage' setting. So if it starts at like 1000 mV, reduce it to 950, then 925, and keep going til you get a crash, then go back to the last stable config. You can probably push the voltages lower by also lowering the max frequency setting. So when you reach the point where it crashes, reduce the max frequency by 50 mHZ and see if you can keep it stable.
@@TechDweeb hello thanks for the tip. I never encountered crash I'll try to undervolt again
Yaaaa I'm staying away from Afterburner. Back when I first got my shiney brand new GTX 970, I got drunk that night, got the bright idea of oc'ing it by maxing out everything the program could, and forgot to set fan curve. Then forgot I did it the next day and left it like that. My gpu lasted a whopping 2 days lol
I guess I should have put a note about Afterburning under the influence in my disclaimer.
@@TechDweeb LMAO
@@TechDweeb hey just wants ask which one perform better i312100f with t400 or 5 5600g
if gpu crashes can i still restart pc?
I saw some tutorials where the core clock is not moved at all so I'm confused I know you said it's temporary but is it necessary?
It's not necessary, but it's easier this way. I do that because it's the easiest way to make adjustments to the curve. If you don't lower the clock speed you'll see that you have to manually drag all the points on the curve by hand. This way it lowers the entire curve, but then you can just adjust one point and it automatically sets the points after it. Like you see at 03:35, I drag the point up, and then click apply, and it automatically adjusts the entire curve, rather than having to drag multiple points by hand. This is just less tedious.
so when it crashes you revent to last non crashing stat ?
Yup
why -250 mhz before start to undervolt?
my gpu is stable on msi kombustor but when I launch a game and play it says device crashed (game is Monster Hunter:World)
nvm just had to increase voltage by +25 even though it was fine on msi kombustor it crashed on Monster Hunter:World
My gpu is old, it doesn't show mV or watts
Is it possible that despite being stable for days, for some reason in game to freeze everything and reboot?
Yup. Sometimes it'll be fine 99% of the time, but very rarely will cause a crash.
@@TechDweeb So the only fix is to increase voltage and see again?
Yeah pretty much. You probably don't need much more voltage though.
@@TechDweeb It really bothers me. In the event viewer I get Error - volmgr,Dump file creation failed due to error during dump creation.
Is that due to the undervolt? Also this: The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0xffffb8915217c70c, 0x0000000000000002, 0x0000000000000000, 0xfffff803a51432d2). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: ba027eea-833e-40fc-a544-619762b5ea77.
Oh it's hard to say from the event viewer log. Are you getting errors only when you're running MSI afterburner with the undervolt applied?
Can we undervolt both cpu as well as GPU?
Yup! That's what I do on my main system.
i once undervolted my little brother's brain and he drooled all over the house for a week...
You need to make sure to adjust the saliva offset to compensate.
1068 mv to 800 on my rtx 3070 70 to 50 degrees Celsius 100% fan speed to 60
Solid!
i think there is "iChill" on amd graphic driver, please try it
Yup. Actually I've had better luck setting the undervolt manually in AMD's Adrenaline software. -100mV on the 6700 xt brings down temps by 5ish degrees with barely any difference in performance.
I'm sorry my guy, I love the video format and your "dialogue" for lack of a better word, but
I just can't do the voice. I'm sorry =[ Don't personalize this please. And don't stop making videos.
Good luck my guy
I understand and genuinely appreciate that you gave it a chance. Not for everyone, I totally get that.

The 40 series doesn't undervolt as well as previous generations. I don't bother with my 4070 ti.
my gpu stuck on 200mhz in msi afterburner help pls
If you're not able to adjust the clocks or voltages or whatever that probably means it's locked down by the vbios (the manufacturer doesn't want you to be able to adjust them). Not much you can do easily in that case, unfotunately.
@@TechDweeb You can do some advanced stuff like flashing a different bios that’s not locked.But it’s risky if the card doesn’t have a dual bios switch.So if the bios corrupts you can simply switch to the alternate bios and fix it.I’ve done this before using guides posted on forums.There are also programmers that create custom bios for GPU which you can find online.But I don’t recommend inexperienced users do any this.

@@naderkhaled7738 i don't think you should undervolt a intergrated graphics, only dedicated graphics cards....
you kind of sound like the nerd emoji but good tutorial
The nerd emoji is based on me ☝️
why do u sound like john lennon?
... what you actual do its overvoltage..... you decrase on all line mhz with the same amount of voltage..... Back to school
Nope! If you watch the vid I decrease the mhz, but then I bump it up OVER the stock. So the MHZ is higher, at a lower voltage.
@@TechDweeb you rly have no idea what are you doing ....... You do undervolt only for highest frequency but rest is on overvoltage. And we know GPU is not always on highest frequency especialy on games where we dont need fullpower of GPU.
