I have a setup with 6x Asus RX 580 Dual OC - all with modded VBIOS.
Five of them are running without any issues. But one card is generating
about 10%-20% invalid shares. I have tried numerous settings changing
core clock, mem clock, core state and core voltage. But no matter the
settings I keep getting around the same percentage of invalid shares.
Is this just a case of bad Silicon Lottery or is there something else that I can try?
