Hello everyone! So i've build a new gaming pc and i tried to undervolt my gpu, i while i was playing Forza Horizon 5 with everything maxed out at 2k resolution noticed my GPU wattage draw it's kinda low 125-145w for some reason, not that it disturbs me but i was wondering maybe im doing something wrong and i might damage everything. So i will add the link with some pictures maybe someone can tell me if everything is alright with it and those are my pc specs.

PC SPECS:

Gigabyte B650 Eagle AX

Ryzen 7 7700 (Non-X) [Undervolt: 80 Lvl: 2 All Core, Negative, 20]

DDR5 G. Skill 2x16GB 6000MHz CL30 EXPO on

Gigabyte 4070ti Gaming OC
 
Note that your memory offset is in MHz, so you're looking at a +1.45GHz memory OC in your settings there.

Also, you're not undervolting, you're underclocking and overvolting with what you've got set. Stock curve was 2550MHz/850mV, you've got 2550Mhz/900mV. If you want to undervolt, your new curve should be ABOVE the stock curve. Easiest way to do this is with a positive value core clock offset (try +200-300MHz).

Other things to try:
  • I typically run my 3060Ti at 70% power limit. I lose about 100MHz off the top, but little/no FPS drop and saves 30-40W.
  • If you want to cap your frequency (in a saved profile), start with that +200-300MHz offset, then go into the freq/voltage curve and pull all the points that are above (say 2550MHz) back down to your desired cap. Doing this will save power, potentially more than what the power limit setting would, and will also maintain a consistent max frequency. Doing the power limit-ation as above would result in a fluctuating max frequency depending on GPU load.

Well I see 144FPS exactly, so do you have V-Sync, FreeSync, or G-Sync on? GPU will use a lot less power if you have a frame rate limit in place.
This^
Don't use V-Sync with VRR enabled. I generally set a FPS limiter in the Nvidia driver settings to be 5ish FPS less than my monitor's max, so 140FPS in this case. That prevents stuttering.
