Some guys are just mean here.. I know i'm a noob on this forums but cmon we gotta help each other out.. I asked if I should mod my bios and not one person answered me. Anyways I went ahead and did it glad I did and don't know why it took me a year lol.. most cards get me around 29-30 even one card does 31mhs... Now one set of cards gets to 31mhs but with tons of errors.. so i lowered clocks. overnight each card got around 30 errors is this bad? If I clock those cards lower I get MHS lowered then before modded.. Should I try another bios on those? Also if somebody could point me to a good modded vbios repository would be awesome thanks.
