Hi there, thanks fo the quick reply,

That's what I suspected
I see, I will invest then and come back to you
what about the freq you recommend ? -->>>  --gekko-2pac-freq 150
for sure I will add a fan too.

FYI I strictly followed the following tuto : https://speedwealthy.com/money/how-to-configure-minera-on-raspberry-pi-for-gekksoscience.compac-and-2pac/UQndxAfk-hM.html

Thanks to you !
