Having an issue... As I good remember I didnt read about that here before. I have 3 rigs 1x 7xSapphire RX580Nitro+LE / 1x 7xSapphire RX580Nitro+OC / 1x 3xSapphire RX580Nitro+OC. All cards are bios modded.
I use the same settings in all my rigs and DUAL mining ETH+XVG.

mem: 2200mhz / 885mv
core: 1180mhz / 885mv

Today I check all my rigs with HWinfo and on my 1st rig with LE cards, all GPUs has a bunch of memorie errors. Other 2  rigs has zero or a few mem errors. Im play with mem/core/mv settings and try all possible but no change in mem errors. The other thing is that Claymore shows me 300-400 invalid shares (if you see this offen make sure that you dont overclock it to much, blablabla) on #GPU3 in 24 hours (did not do that earlier)

Any idea?
