Question RX 580 does not show display with ASRock H61M-VG4 mobo

[ProgamerIV]

As the title says.

I have just put together a PC with the following parts:
-ASRock H61M-VG4 motherboard
-i7-2600
-2x8GB Hynix 1333MHz RAM
-XFX RX 580 4GB graphics card
-FSP 500W PSU
-SSD+HDD, fans, case, etc.

The PC turns on, peripherals turn on, but the RX 580 shows no display at all.

I tried to connect my display to the motherboard's D-SUB port, and voila, it worked - but of course with the onboard graphics.
I thought it could be that the dedicated GPU is disabled, but no. Advanced -> North Bridge configuration -> PCI Express was set already as the primary gpu.

I have updated the BIOS to the only available update at ASRock's support page (1.40), still the same.

Could it be that this motherboard just cannot run with the RX 580? Shouldn't it be backwards compatible with PCIe 2.0 boards?

Thanks,
Alex

Now I have found a 3dmark benchmark result with this motherboard and the RX 580... Something's obviously wrong, then. What could it be?

For anyone wondering: it seems the XFX version of the RX 580 just won't work with many motherboards.
Tried a few other 1155 boards, including an Asrock PRO3, all with the latest available BIOS versions that are supposed to support PCIe 3.0, but to no avail.

Surprisingly after all, one of the lower-end boards, an MSI H61M-P31 was the only one 1155 board I got to work with this card.

Interesting fact: I have since bought a Sapphire Nitro+ RX 480 8GB and Pulse RX 570, tested and they both work fine with all the motherboards this XFX 580 wasn't working with.
