Hi Claymore
Have you managed to replicate the issue with 12 gpu systems
issue: on version 9.8 if you have more than 3 amd cards in a rig of 11 or 12 gpus ethdcrminer hangs on Algorith ASM, if you start the instance with 3 amd cards and the rest nvidia then it starts mining. then you have to start another instance of ethdcrminer with the remaining cards, .
This issue was also experienced by a youtube channel Cryptomined where he had to have multiple instances on 9.8 running in order to use all the cards.
When all cards are selected after the cmd window hangs nothing but a hard reset solves the hang.
Hope that helps, if you need any more info or troubleshhooting with this regards you can let me know.
thanks
I don't have appropriate hardware to test 12GPUs configuration. You can try some different miner to check if it is more stable, because the reason can be not in miner. Also try "-gser 1" or "-gser 2" option.
that's been happening to some of my rigs inside log. That's usually the last line of message before the whole system reboots itself or hang in a loop required hard restart. Thanks!
