Undervolting GPU should be standard procedure

Yeah comes down to cooling

if temps aren't good then undervolting can in cases result in better performance.

higher voltages will provide better absolute performance however you must have cooling to support it. No one sets performance world records with undervolts.

GPUs are generally slightly overvolted from factory to reduce RMAs by improving stability. Just cause you can undervolt and be stable doesn't mean the next GPU will be able to do the same.


I belive overclocking and undervolting tools should be in graphics card control panel software

I also agree and Radeon Software got you covered.

Did you mean anything by describing nvidia's customers as "fans" and AMD's customers as "users"?
Or are you putting forward the argument that AMD's kit has traditionally been less efficient thus making undervolting more appealing?
Or that manufacturers have been routinely setting up their AMD-based cards with higher than necessary voltage out the box?

i never meant anything by fans and users lol was just an oversight by me. the rest was just me stating what i have witnessed over the years - if its something is done by amd fans/users then it is because the product is bad, if its done by nvidia fans/users then its really good that you can do it.
 
Mines getting on my nipples everytime I try to set an undervolt it keeps putting itself to stock

It's 931mv as stock but I find 900mv keeps the temps down where I'm happy but keeps reverting itself
 
agreed so worth while in the long run, I so far been testing on 3080FE 893mv @1905 ingame it jumps to around 1920-1935 and its beating stock performance easily while lowering temps/power/ fan I also noticed nvidia set very relaxed fan curve they almost want the card to reach 75c before it really kicks in and for me just setting it aggressively to where the noise level is fine and highest I can go before the noise bothers me which is around 53%

Yes but only CP2077 causes any issues.. running full RT and DLSS so guessing it just needs a bit more juice when all cores a working at full whack. I've been advised that CP can be finicky with mem OC's aswell so +1000 mem might be not be helping.

I had a *very* stable undervolt/overclock on my 3070 and only Cyberpunk CTD'ed with it - knocking down the frequency of the OC one notch (2040 -> 2025) fixed it (and also allowed me to push the VRAM OC to +1200 from +1100).
 
From user perspective, undervolting is overclocking.
You will need to spend time tweaking and testing for stability. And get rewarded with occasional crash if you do it wrong (like above cyberpunk examples)
Many will not want that inconvenience.

Luckily we are on overclockers forum, so you are right undervolting should be standard here.
 
This thread was a useful head's up, thanks :)

So far I've got Afterburner set to a 78% power budget, temp limit reduced from 83 to 75, and the card is consistently clocking 50-100mhz higher, with no visible issues. Seems too optimistic, so might get a proper benchmark going on it; my usual gaming is pretty easy on the GPU and I suspect it's not really 'stable' per se.

Can you set per game profiles with whatever software you're using? I do this with the AMD software rather than a global profile.
 
I always wandered , if by undervolting a card , you end up with a better product ( less heat, stable clocks , higher clocks sometimes, more energy efficient ..etc) why is it left to the end consumer ? why AiBs do not do this themselves, it would be an excellent piece of marketing / advertising , why doesn't nVidia shouts look at our power efficient cards... ?

Because it is not feasible to do this sort of tuning at an individual card level, it would take way too long to test and validate.

They have to give the cards a good margin to ensure all the chips they put in can handle the same settings. Otherwise it's RMA city for them.
