Claymores miner is reading my RX 580 as a RX 480. I have 2 RX 480's as well. Is this normal?

It is normal.

Ok thank you. I just got this RX 580 in today, the XFX 580 GTR black edition.

After a few minutes i get the error "GPU 0 hangs in OpenCL call, exit"
In which miner then attempts to restart but doesnt.

I think, ok maybe i need to bump up the virtual memory size from 16,000 to 32,000.
Still doesn't work. Same "GPU 0 hangs in OpenCL call, exit" repeats.

So what i did then was take out the 2 RX 480's to see if it will mine on just the RX 580 which it ran fine.

What do you suppose the issue could be?

EDIT 1:Also noticed this in red on the miner just now: GPU #0 returned incorrect data! 208533

EDIT2: downclocked GPU0(RX 580 btw) to 1385, ran for longer. Then GPU1 hung up and "GPU 1 hangs in OpenCL call, exit" occurs.

Re-Install drivers

Update: I installed the new drivers(17.5.1), the errors and "hangs in OpenCL call" replicated itself in GPU 1 again.
So i decided to rework my setup, putting one RX 480 riser USB attachment in the pci-e slot 2, the RX 580 is installed in the pci-e slot without a riser 1 and the other RX 480 riser attachment in the smaller x2 slot i think its called. Now up and running smoothly for the past 30 minutes so far without any errors reported.

I haven't tried the new 17.5.1 driver - but I was having a similar issue. Always GPU 1 - in all 4 machines that I had. It was weird. They were all RX580's and until I did this - https://bitcointalk.org/index.php?topic=1900035.0 - Once I did this driver trick using an older driver, it stopped.
