I’ve been stuck on this for a while. With 4 cards, mining works perfectly fine. Even removing one of the GPUs to swap in the 3080 works. But once there are 5 in total, the 3080 consistently fails.
Sometimes it silently fails. Showing zero error in the console’s mining output. While other times, it causes a “invalid device ordinal” error. Which bricks the whole system. While running NBMiner for ETH.
What have I tried?
- enabled 4g decoding
- set each PCI-E slot to Gen 2 (also tried Gen 1 for kicks)
- mining mode enabled (by default with this board)
- replacing the PCI-E riser
- moving the PCI-E slot for the 3080 around
- updating NVIDIA drivers. Currently on the latest 470.63.01
System Info
- Motherboard: TB360-BTC PRO 2.0 BIOSTAR
- PSUs: Corsair AX1200i + AX1600i
- Hive OS Version: 0.6-210@210913
- PCI-E Slots 0-4: Connecting to GPU risers
- PCI-E Slot 6: Older wifi adapter
- Running off Corsair 512GB GTX USB currently
The AX1200i powers the board and the two MSI 3080ti cards (3 8-pin), while the AX1600i is connected to the two ASUS 3080ti cards (2 8-pin), and the MSI 3080 (2 8-pin).
Any help is appreciated!
