Claymore's miner doesn't detect second GPU

[rawbert]

I have 2 RX 480 ref cards, they show up in device manager and wattman, but only on of them, GPU0 shows up in Claymore's mining software. I tried 5.2 and 5.3.
Windows 10 Pro, 64bit, crimson 16.7.3 (tried 16.7.2 too), virtual ram set to 16gb, gpu0 mines fine @24.5Mh.

Ran these in batch file:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

What am I missing here?

I think it might be related to Crossfire, try disabling CFX.

Thanks, but my asrock h97 anniversary mobo doesn't even support crossfire.

Have you tried ethminer robert? Claymore's might have an issue detecting it but maybe ethminer would.

Trying to get it run now, but I'm getting an error:

But when I run devices.bat it only sees only one gpu, 0, so same thing.. I think my mobo might be defective..

I think the command you ran was the issue, try downloading the software from here if you got it from a different source:

https://github.com/Genoil/cpp-ethereum/tree/master/releases

and run "ethminer.exe -G -F 2 --farm-recheck 200 -S us1.ethermine.org:4444 -O YOURADDRESS.yourworker"
