Now my 24h nonstop runner second PC with 5090 card is finished and optimizations has begun. During undervolting tests I’ve made an interesting discovery. When I limit my 5090 to 850mV @ 2250Mhz flaten the curve, the card’s power consumption drops down by about 150W and while I saw short peaks of up to 580 watts before undervolting, the highest peak I’ve had now was 402W. 
Now the incredible thing that I can’t explain: even though I’ve limited the card hard, I have slightly more FPS into TVAI and slightly shorter ETA times, so this is crazy! GPU Temp now 55°C or lower (room temp 25°C)
Either the TVAI fps display is wrong, or the number of tensor cores is crucial and less core speed isn’t that important and my increased VRAM speed more than compensated it

after (running stable!)
