Anyone using a Ubuntu 7 GPU optiminer rig?
I have two nearly identical rigs (each):
MSI Z97 Gaming 5 MBO (MBO's are sequential serial numbers)
2 EVGA 1300 Gold PSU
8 GM RAM
7 RX-480 8GB (factory OC)
250GB Samsung 850 EVO SSD
GPU's are mostly Nitro Sapphire but have a few XFX cards.
I used cryptomined work as a starting point (thanks for this work).
Getting Linux to recognize all 7 GUP's was a bit of a challenge but I have a stable (pain in the ass) install process now. I would be happy to share if anyone needs.
I am averaging 210+ S/s on each GPU with this setup.
Both rigs show reduced S/s on GPU2 over time. One rig drops output all together and the other drops down to ~50 S/s and stays there. neither GPU2's are off doing something else as their temperature also drops accordingly. Rig that drops to zero on GPU2 (not even listed in log output) hangs, (Ctrl-C) does not bring down miner. Sudo Reboot also then hangs. I need to do a hard reset. Rig at ~50 S/s on GPU2 functions normally for shutdown.
Ive swapped GPU's around, removed GPU's and mined with fewer cards, and mined with only GPU2. results are always the same as above.
Anyone else having this issue?
