Hello Guys,
Recently I have built 8GPU VEGA mining rig. The rig contains: 5*MSI Radeon RX Vega 64, 8GB+2*Gigabyte Radeon RX Vega 56 8GB+1*Gigabyte Radeon RX Vega 64 Gaming
OC 8GB Video Card.
except the HBM problem, i had another problem when I was mining GRAFT on certain pools. some times, the pool will reject all share with reason "Unauthenticated". please refer to the log below. And the rig will be stuck in this status forever until a reboot.

[23:38:40] !Rejected by pool! Reason: Unauthenticated
To address this, I developed a monitoring powershell scripts to monitor the accpeted shared by pool. if shares are not increased in 2 minute, then the rig will be rebooted.
it works pretty well since it also address another problem i had, some times rig will be doing nothing if one card is not hashing.
I am not a professional powershell developer. This was my first time to use powershell and I developed this script one night with the help of google.
Here is the link for your reference in case you are having same headache.
