  • Depending on the software you could drop the power target of the card basically to the non XTs level. I know on Nvidia MSI Afterburner lets you set it to whatever the hell you want.

    What I’ve found if you want better efficiency is to clock limit the card. Find a voltage that gets you to about the power limit you want, then just make any further steps up be the same frequency and it shouldn’t bother with those voltages. In Afterburner it’s ctrl F.

    My 4090 I have clock limited to 0.875v (lowest it will go) and it only consumes about 220-250 watts under normal loads, and under really heavy loads it’s about 300 (350 is the most I’ve seen). It’s been a while since I’ve tried that stuff on AMD cards, but based on my 5700XT in Mac OS I think it still works the same.
