HIve OS Mysterious: System does not run stable, reboot every hour

Hello community,

I have a small or rather big problem with my rig, which is already a bit mysterious. Unfortunately my system is not stable and reboots every hour. I am afraid that it is related to the MSI RTX 3080 Gaming Z Trio. But first a few key data about my rig:

CPU: Intel Celeron G3900T
GPU: 1x MSI RTX 3080 Gaming Z Trio / 8x GIGABYTE RTX 3070 Gaming OC
RAM: 8GB Patriot Viper Steel DDR4-3200 DIMM CL16 Dual Kit
SSD: 240GB Kingston A400 2.5" (6.4cm) SATA 6Gb/s TLC NAND (SA400S37/240G)
MOBO: ASROCK H110 PRO BTC+
riser: 9x Delock Riser PCI Express

mining pool: ethermine
Miner: T-Rex

Settings:

Back to topic. I have already disconnected my 3080 and the other graphics cards are running stable - 24h without reboot. I flashed the 3080 with different BIOS, but unfortunately that didn’t help either. Can it be that…

  • Card is rebooted/disabled due to thermal throttling?
  • Riser damaged?
  • Wrong settings?

Or do you have any other suggestions? - as error message I get: t-rex low hashrate (0 kH/s) - restarting and in console 20210605 12:54:19 TREX: Can’t initialize device [ID=4, GPU #4], cuda exception: CUDA_ERROR_LAUNCH_TIMEOUT, try to reduce overclock to stabilize GPU state
