Thats a very nice idea you had there my friend ,in some occasions the undervolt can be quite beneficial especially to save some energy and thermals,the performance difference is there but the powerdraw in some cases is way higher. I find the undervolt procedure as fascinating as the overclock procedure I like to know both those limits on my cards aswell.
Thanks for taking the time to do this video. Very helpful. I have never considered undervolting my GPU. I have always had it overclocked because I have been able to keep its performance stable and the temperatures cool.
In my tests 25xx 925mV seems to roughly be the best to go for. Performance per watt gets better the further you go down and that's roughly where the performance loss becomes a bit much. It's 94% the performance for 74% of the power. Made a crappy spreadsheet and line graph if anyone's interested. Not many data points though.
Great video bang. So many people will find this useful. I've been running my suprim x 3080 12gb since the day i bought it at 0.850Mv @1860. In most games runs between 210 and 260 watts. Stock at 100% it runs at 2040mhz 1.093v 390 watts. I did get some good silicon as it will hold 2250 at 1.1v 425watts in unigine heaven.
One thing that Bang4Buck forgot to mention, you can almost always undervolt your GPU to get exactly the same performance you get at stock settings, reducing the needed voltage and reducing temps and power draw. It obviously takes a little bit of finesse, but you can get there. I don't think undervolting is as necessary as it was with 3xxx cards, as the 4090 runs cold even eating 450W, but it's always worth considering.
I was one of many unlucky gamers to get a defective RTX 4090. Constant crashes and BSOD in high demanding games. Undervolting fixed this and stopped all crashes.
Having a Mini ITX build in the Coolermaster NR200P Max with AIO and 7950X 3D I'm all about stability and as cool temps as possible. The horsepower is already there now I just want to have as cool as possible system. Thanks for the tips. Between this video and the MSI video from several months back which I saw they highlighted your video as well it really helped me understand and broke it down for a laymen.
Thanks for this guide. With my TUF OC 4090 I got a small increase in Cyberpunk performance whilst saving 70 watts of power, avg 330W in gameplay. Amazing. 2745/0.95v/1.08% P limit/+1285 mem clock. There could still be room for further improvement. Cyberpunk benchmarked at max settings with PT on, 4k DLSS auto + FG on gives an average of 100fps, min 60fps. Using a 5800X3D CPU.
Thanks for sharing this, Going to try it on mine. However what a bizzare decision from MSI. 4090 suprim X built like a tank,big vaporchamber heatsink, more phases, 4x8pin to 12vhpwr which theoretically should be enough for 800w power Limit. BUT they decided to put 520w bios on it. Why msi... why...
It's not only MSI. Every single 4090 is built like a tank because they were given specifications to account for a much higher power draw. Honestly, I prefer it this way.
I use 2850Mhz with 1V and I try to keep temps around 65-69, so my fans run at 1600rpm max. All of this with Gainward non-gs version. If I want super quiet then 0.950 with 2715Mhz.
Without undervolting my 4090, can i just reduce my power limit and be ok with electricity cost and power draw? I am reading that power limit to 70% is insanely good with a minimal loss.
Is it easier to do undervolting with Nvidia Geforce app or with MSI Afterburner? I've tried to follow several tutorials and this seems a bit more granular. With my 7900XTX it was a bit easier, but now I have just bought a MSI 4090 and don't want to mess anything up.
So I’m one of the few ppl running this card on an x470 mobo with pcie 3. I’m running .975/+1000/2790 clock and it’s around 350w in 2077.. doesn’t break 65c core/80c hot spot at less than 60% fan speed on asus tuf non oc. +133% pl, but throttles at 80c max just in case something goofy happens with fan control software. Ur card must be water cooled with those temps..I wonder if I can do a .950 and gain the lost performance back by going to x570. I think it’s 3-4% loss for pcie3. Not sure if this would work.. and obviously not worth upgrading for alone. But I just got a couple 990 pros to raid 0 and just need a mobo to match with it. Thinking MSI edge max.
Why not just lower the power limit, while increasing the core clock instead ? I'm getting 2835mhz on my 4070Ti with 80% power limit instead of the 2970mhz I get with 105% power limit . I have the core clock +210mhz. My power draw also went from around 285w to around 235w. Temps went down from around 66c to 58c
Because at 4K ultra settings, it is very easy to hit the power limit on the RTX 4090 if you reduce it. Then your clocks will start to fluctuate. Try playing Cyberpunk with Ray tracing at 4K with a reduced power limit. That game can hit 500W easy
@@Bang4BuckPCGamer In that case, it should just be a matter of running the same OC but using different Afterburner profiles with separate power limits for a per game basis (Raster vs RT, heavy AA, etc). Quake 2 RTX can make even 865mv/2.5GHz draw >340W afaik, but a lot of games don't really touch that kind of power in most situations (Shown by yourself by the majority of examples in your vid staying under 350W even with .95V/2.7GHz, with only F1 2021 approaching ~390W). Flattening the curve should only really be a necessity in the case of those with more weaker power supplies while also rocking a power hungry CPU (I.E a SFF build rocking a 13900K + SF750), otherwise for most people it's unnecessarily sacrificing performance while under lighter load scenarios, but we can agree to disagree if you so please. The mere fact that you're doing the method of core offset + flattening the curve itself to retain effective clocks vs ruining effective clocks by raising one voltage point puts you leagues above damn near anyone else showing Lovelace undervolting/overclocking mate.
@@erfgthygreas1709 Different games can range in power draw, so one can optionally set different Afterburner profiles depending on the game. But this is mostly out of redundancy, the overclocking method I mentioned (Simple Core Offset + Power Limit) is usually enough.
I'd be trying to keep core up and drop power I don't want to lose that much performance I just want a little heat down not bothered really about wattage
As someone who's a noob when it comes to this. Wouldnt just setting an FPS cap achieve the same result? Just cap it at lets say 60 instead of having it run at 90.
Why compromise on using your nice 120Hz 4K display to it's pottential? You can save power, reduce temps and fan speed if necessary without a 60fps cap.
@@Bang4BuckPCGamer But it achieves a similar goal? Less frames needing to be pushed = less power usage, lower temps and lower fan speeds needed. Undervolting just does the same thing except it's not locked unless I'm missing something. You still get less frames with undervolting. A better test would be undervolting and seeing average fps then comparing that to the FPS locked at that average frame rate to see if there's a difference.
@@Bang4BuckPCGamer That's not what i'm saying though. I'm saying since you lose frames, lets say during undervolt its 100 and without its 120. Why not just lock the fps at 100 and achieve the same results? Or more importantly, would the power draw be changed at all between locking the fps and undervolting.
@@Plague_Doc22 it would only be effective if you could achieve that frame rate. But there are so many games that play well over 60, but can't lock 100. Like the last of us for one
Thanks, so in the end is not really worth it, 4090 undervolted will be like 10-15 fps better than 4080 at same wattage? for extra 600£? neah... was looking for a 4090 but is not worth the money, will go for 4080 :). Thanks again.
Lmao the 4090 smashes the 4080 - This is an undervolting "guide" This can be tweaked to gain even MORE performance OR as many will do who buy the 4090, leave at stock or OC without undervolting, I think you need to go and see how the 4090 really pulls ahead by double your highest mention and more - What a clown

Yeah sure only 7 degrees celsius, but these coolers were already overbuilt so even overclocked they don't run very hot. What really matters is the thermal output in your room. Saving 100w of power turns a PC from a 500w space heater to a 400w space heater.
