[QUOTE=Mark Rose;623711]If you want to save power, setting a lower power limit on your GPU is useful. I cap my 270 watt 3070s at 200 watts and get 95% of the performance.

You have a good amount of RAM to run P-1 work.

600000 / (43 * (24/9)) / 365 = 14.3 years[/QUOTE]

Undervolting is wayyyy better for GPU than powerlimiting itself. Also, while undervolting, it will reduced the max power draw with it, so it does the same thing. My 240W GPU is sitting at 160W, while powerlimit is not reached. 0.925V at 1965 MHz boost, memory at 1900 MHz.

What does the formula mean, that you gave 14.3 years? I have never done P-1, so I am missing the context.

I haven't played with GPU undervolting since it's not straight forward on Linux.

14.3 years is how long it would take to use up 600TB of endurance at the 43 GB per 9 hours rate you posted.

[url]https://linustechtips.com/topic/1259546-how-to-undervolt-nvidia-gpus-in-linux/[/url] this may help

Thanks for explaining what 14 years meant, yes, maybe I don't need to worry about it :D
