B550 pro4 support

   Hi!

I updated my computer and ran into a problem I didn't understand.
Asrock B550M Pro4 motherboard with R5 5600X processor works with any graphics card except RX 5700. Checked with RX480, R9 280X, GTX1660super, GT210.
RX 5700 (reference) graphics card works with any motherboard except Asrock B550M Pro4. I tested it on MSI Z87-G45 Gaming, Huananzhi X79 Deluxe ver.14, even with MacMini via Thunderbolt as an external card it works.
But together they do not want to start.

The post card does not show anything on this motherboard, and the Post Status Checker indicators on the board are flashing BOOT - CPU / DRAM. The check does not reach the VGA indicator, the process is repeated many times, the speaker is silent, there is no image.
BIOS version is P1.70.
The memory is configured according to the XMP profile to the standard 3733 MHz for it, it works fine with other video cards.
Resetting to default settings doesn't help. Removing NVME SSD and PCI-e Wi-Fi, changing the PCI-e version from Auto to Gen4 or Gen3 also does nothing.

Where to dig further?

	I have ordered a asrock b550m pro4 recently and with the current bios version on the board it cannot support my 5600x. I do not know how to update/flash the bios and it would be great if someone could tell me how.
