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.
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."
