Hi everyone,
I just finished to configure a 3x 7950 sapphire vapor-x OC edition. It runs very well at 1920kh/s on xubuntu and it takes 800watt from the wall.
But I want to improve the energy efficiency.
First I have auto-fan with a target temp at 75C on CGminer. Second, I try to undervolt with CGminer, but the command doesn't change the voltage.
Current config : Engine: 1080 Mem: 1500 volt: 1.15
I read a few things on how to undervolt vapor-x on windows, but does someone know how to do it on xubuntu ?
Thanks a lot.
