soo, not so pleased with the result of this. it ran 30 min, total hardware errors - 0. In the version i downloaded there was no "gpu memory erros"
sadly when i closed it my miner restarted and 2 cards is no longer detected by windows :/
starting to regret buying vega cards...
Don't worry, we go to find.
Unplugged alimentation from the wall, wait 30sec and try again.
Have you modded the bios ? have you a strap to boot on the second bios on the card ?
And sorry Vega doesn't have memory error monitoring...
So first try on other pool to see if its the same, if yes try to underclock the CMem just the time of testing 1-2 hours.
