XFX RX 5700 XT Thicc III Ultra 8GB not detected by motherboard

[Croiwanssant]

Upgrading from an XFX R9 390, just bought an XFX RX 5700 XT III Ultra and it isn’t being detected by my motherboard. I’ve tried:

·         Removed and reseated the card

·         Tried 2 out of the three PCIe x16 slots (it’s too big to use the third)

·         Updated the bios (it’s now up-to-date)

·         I don’t have another system to test it in

·         I don’t think it’s a psu issue I’ve got a 650w psu, it should be enough

·         When I check the bios it doesn’t appear at all

·         It doesn’t appear in manager

·         It isn’t detected by AMD software

·         The LED indicators are blue, which I’m pretty sure means it isn’t a power issue

I’m contemplating returning it but wanted to make sure I haven’t missed anything. I’d rather not return it if it can be helped.

 

I have both the R9 390 and the 5700 XT in the rig at the moment. The fans spin in the 5700 but that’s all.

 

Any ideas?

 

Thanks

I would try your old 580, and if that works, I would put my money on your card being DOA.

You're probably right- which sucks I was so looking forward to this! I've never gotten anything DOA before
