Anybody knows when setting the gpu voltage too low, does the System crash immidiately showing this driver Crash bluescreen
Or can it also take longer like a few hours to 1 day if you are near the "limit"?
Had some System freezes while adjusting gpu voltage but only after the miner was running for 5h or more
It depends. If you use MSI AB or Trixx to adjust voltage offset - you apply this offset to all voltage table, even for standby voltage (300 MHz, 0.8 V).
Ellesmere in most cases becomes unstable when Vcore less than 0.725 V.
