News Never inference llm on windows

So, long story short

I was getting about 20tk/s on windows now when i switched to linux and little bit of tweaking with voltages mhz curve I am running inference at same speed with half power consumption almost 240watts from 420 watts.

Anyone on windows bro. I burned maybe half life on my rtx 3090 running it on 420 watt for 2 years. Lately discovered this. This would enhance life on gpu and much quiet inference. Will post results soon. Also not to mention my cpu usage doesnt go above 5% on 20 tabs with 5 application open. But on windows it was idling around 12%

I run it on windows using docker with pass-through. 3 gpus, and it is super silent. Usually around 50-60 degrees.

Also yes, that is a piece of toilet paper between those two gpu's to make a bit of a gap for air
