Hello
Recently built 2 rigs using this software. They are 6 AMD sapphire nitro+ rx580. No bios mod, overclocked enough to get 182 MH/s and no rejected shares. Using latest AMD drivers 19.6.2. The first one is working perfectly fine and mining properly with no problems, but the second one, despite having a good hashrate, is not very stable and crash after few hours (phoenixminer.exe stopped working). First one mining ETH and second one ETC. Anyone having any ideas why is this happening ?
current config.txt file (basically the same for the 2):
-pool eu1-etc.ethermine.org:4444
-wal XXXXXXXX.rig2
-proto 3
-cmd 2
-gt 12
I had one gpu like that. Was a bit flaky at higher temps..also randomly dropping hashrate. I took it out of the rig and all is stable.. run that one card on a gpu benchmark like superposition and see if they are similar in results. I found I had a 15% difference - card was therefore faulty..sent it back
All the GPUs i have on this rigs are perfectly stable, the hashrate is very stable (it's about a -+ 0.1 Mh/s evolution with time). I don't think this is hardware, because it's not giving me any sign of hardware malfunction (memory errors, incorrect shares,...). The temps on the cards are also nice (max 60°C or 140°F).
