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.
For my rig I am having a couple thousand errors in a day. I have 6 Sapphire Nitro+ RX580 total hash 185 Mh for solo mining with 800Watt from wall. System never crashes up to 48 hours. I always restarted system before that time, maybe it could run even further. So i think you can overclock your card a little bit further. Use HWinfo64, overclock each card seperately and if there are no huge number of error in couple minutes you can use that values safely.
