I'm using hive OS to mine ETH with a Vega 56 and two small cards (1660s) but when I on the rig it reboots instantly once mining is about to start, I'm using teamredminer for the Vega and Trex for the 1660s, another thing I noticed is this
GPU 0: 1660s
GPU 0: Vega 56
GPU 1: 1660s
Shouldn't that be GPU 0, GPU 1, GPU 2....

First, reinstall the video cards on the mining farm. Green video cards (Nvidia) come first, then red video cards (AMD).
Reinstall Hive OS. Use the latest version. Check the miner settings, it may be a configuration error.
