OK, I'm old but I love my gaming. I like to run games as pretty as I can get them because, to me, the graphics are as important as the gameplay. If you disagree with this and want to have an argument don't bother responding.

I have a Gigabyte Windforce V2 4090 and would like to know how to get the best out of it for the least power.

Please do not post YT videos because I really struggle to watch them. Written instructions are preferred.

I have downloaded MSI Afterburner but do not even know where too start.

Thank you to anyone that can respond with helpful instructions.
 
You really do not need written instructions for this, as this is one of those things best followed along in a visual way because at first it can seem complex but is really quite simple. The easiest to follow video guide I have seen is the one below, and you can ignore the latter part of it which focuses on overclocking since all you want is undervolting and the benefits that come with that, so just the first half of the video. Pause along the way and continue at each step and you are done.

Thank you for replying and for putting in the effort to find a simple answer to help me. It's late just now so I'll try and watch this tomorrow.

For reference my Zotac 4090 Trinity is sitting at 2730MHz core and +1100 on the mem (will make sense once you're through the video) - The voltage for my card is 975mV which results in just over 100 watts lower power draw and quieter GPU fan speeds. This also gains up to 10fps vs stock.
 
Managed to go through this tonight, took about 7 veiws. However I now have 2685MHz clock, +1200 on the mem and a voltage of 975. Totally stable.

Will tinker a bit to see what else I can tweak out of it.

Thank you so much for taking the time to help.
 
Managed to get 2850MHz with +1200 @1040mV

Volts obs a bit high so I need to tinker a bit.

2800mhz at 975mv is where im at with the curve in MSI Afterburner. Been running like this since i got it and its really cool and quiet.

I tried a 3ghz overclock and gained 5fps but the power draw was 450w compared to my undervolt at 260w.

Memory clocked to +1500 with the undervolt.
 
Plumped for 2790 at +1200 on 975mv. Will leave it there I think.

Thanks to all for your input.
 
i run 2670 @925mv on my 4090fe, people going too high on memory lowers your fps, you need to be running a stress test when you change memory, when you see the fps start to drop lower the memory speed so its not erroring out

Cranked it back a bit to 2700 at +1200 975 and very happy. Just need to build the parts I bought last year to upgrade the rest as my i9-9900KS is holding the card back.
