Second GPU is not recognized - hashserious - 04-18-2019
Hello, first timer.
Got rx 580 working, then added a second card (also rx 580), but hashcat doesnt recognize the second one.

RE: Second GPU is not recognized - philsmd - 04-18-2019
your clinfo basically proofs that it is not hashcat fault because also clinfo only sees a single RX 580 (there is only one GPU in your list).
I would suggest reinstalling the driver and/or messing around with xorg.conf etc (reinstall of the driver could be easier and fix all problems).
RE: Second GPU is not recognized - hashserious - 05-05-2019
For future reference:
Got it working after installing "rocm-smi" from aur(arch user respository). It may be bugged, so may not work for everyone in arch.
Had to "--self-test-disable"(see below).
Then there were 4 devices, which basically means it split every card. "-d 1,3" solves this.
Edit: With -m16800 everything works fine, but with -m2500 the self-test fails(one device, second device works fine).
