I've got 2 systems that I'm trying to reduce power consumption on, but don't want to mess their operation up, i.e., going into sleep mode and shutting down the card, etc.
I know I can turn off stuff I'm not using like sound or onboard SATA IF I wasn't using it. Anyone have any tips or guide for minimizing power consumption on the motherboard/CPU?
After that I'm going to look into flashing different firmware on my Gigabyte 7950's..... I know that should yield power savings and increased hashrate.
I've undervolted the cpu, ram, northbridge, pll everything that I can. Turned off everything like usb 3.0 ports, esata, etc. Only saved me 10-15 watts.
Undervolting the gpu saved me almost 90 watts on one card alone 7950. It was running at 1.18v at something like 925/1250 I down clocked it to 900/1250 at .84v (freak card, edit I only get about 550 khash with this setting but the lower watts, and lower fan noise are worth it to me)
I have a his that is running a .97v at stock clocks.
All measured with a kill a watt. Before and after the undervolts. Had to do it via msi afterburner.
