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 have three Vega cards at the moment. Two Vega cards work well, as soon as I add the third one, there are gray artifacts after the miner has started and the PC crashes. I am yet to test the non-blockchain driver, though.

You mean the GPU tach turns blue? There is a switch on the back of the card, you can choose between red and blue LEDs. The Vega 64 and 56 cards are identical so I use the LED color to mark them -- e.g. Vega 64 = red LEDs, Vega 56 = blue LEDs.

Very convenient.

So you actually had 2 Vega 56s mining on the blockchain driver???

What were your settings?
Did you do anything different when installing the driver

Let me know how the regular driver works for you with 3 cards.

As for the lights, definitely green, found this "There's also a green LED that indicates when the card has dropped into ZeroCore power mode, the power-saving mode activated when the display goes to sleep." http://techreport.com/review/28513/amd-radeon-r9-fury-x-graphics-card-reviewed/3
