Faulty card, or easy solution?

[spaceramen]

Just installed an 8gb RX 580 to replace my 1050 ti, and it's been crashing every game I run about 5 minutes in, usually straight to desktop, but it's also crashed my whole system twice. My browser crashes occasionally as well.
I've DDU'd about a dozen times across a dozen different driver versions, I know the PSU can push out enough power to make it run, I've tried under and overclocking it, and I've already tried a fresh Windows install.
To be sure, I stuck my 1050 ti back in and my system is running fine again.
So, should I fill out this RMA, or am I missing something?

Did you buy a used mining card? It may have a modified bios.

If your board has 2 PCI-e lanes or integrated graphics use atiflash on the 580 with the latest bios from tech power up's database.

Also try updating your motherboard bios, what's the rest of the system?

Drop the power target of the GPU down to 50% and if it then runs fine you'll at least know it's probably the power supply.

Also even if it's new it might have some random issue with the bios if you want to try flashing.

50% power didn't work, flashing it didn't either.
At least I got to see some pretty interesting colours while this thing worked, or didn't work I guess.

Then probably just return/exchange the GPU, unless you have a secondary PC or a friend's PC, or a local PC shop where you can quickly test the GPU in a different system.

Or just wait for the "small" navi GPUs, if they really are coming soon, unless it's just another rebrand, might be a 2060 for $200-250
