RX Vega Error

[Bakhtra]

I got 2 vega that error. 1st if using blockchain driver >> after disable if enable again >> error. If change to updated driver >> can disable and enable >> but low hashrate. Another the radeon writing sometimes on with gpu tach red, sometimes off with gpu tach yellow. Anyone know the solution for that? Thank you.
After decreasing mem, the 2nd card run perfectly.

i bet you got SLI enabled in radeon settings turn it off.  Most the times on boot up you will see one vega with green light

Green? I though that was yellow (actually I'm color blind). I'll check on radeon setting then. I use 4 vega and 2 rx 570. That problem already solved when I change mem from 975 to 950. Do you know about the 1st vega problem, can not enable after disable?
