They use 1.10V each and do about 300-400khs each (scrypt)
I have the stock BIOS

I was wondering if someone had some suggestions to optimize my power usage? It seems 1.10V is really high. Could I not somehow lower it to around 1V? Stock bios doesn't seem to allow me to go below 1.10V, so I probably need to flash it. I tried the flashing to the sapphire 7970, but trying to mine just gave HW ERRORS so that BIOS didnt work on my (non-reference) card
