I have 2 PCs with both 2x MSI RX vega 64 8GB both cannot use the blockchain driver, it shows grey artifactes on the whole screen on both PC, a few secunds after claymore miner starts. With only 1 card running there is no problem. Anyone have a fix for this?
Same issue for me. I have 2 Vega 56s with stock BIOS.
1 card works fine with blockchain driver and I get 38 Mhash at 920 mclock. When I use 2 cards 2 I get artifacts on the screen and the system crashes. Also do see that my 2nd cards GPUtach turns green instead of read.
I reverted back to regular AMD drivers and now both cards run fine at around 34 Mhash at 920 mclock and is stable.
Would love to know if there is a work around or if more folks experience the same issue.
