Debug codes

Open a support ticket with ASRock Tech Support and make sure you link the image
and video:

If it were not for those marks I would suggest taking the board out of the case
and setting it up on top of it's box with just the CPU, RAM and possibly GPU
(if you are using a CPU with an "F" designation). If your CPU does not end with
an "F" then you don't need the GPU, just use the board's display output. You can
go ahead and try this anyway, it will rule out potential shorts against the case.
Without a clear image of that socket I can't tell if it's just a harmless
molding defect, something spilled or a damaged socket. ASRock's Tech Support
department will be able to advise you, likely to return the board to the retailer
you purchased it from.

To be clear, there are steps we could take to troubleshoot here but after seeing
that pic I would contact support and ask them to clarify. Let us know what they
recommend.

I'll uh plug the monitor back in and give it a shot alpha a2 meant that the ram is in the wrong slot

So no display... I tried clearing CMOS and trying each stick again one stick produces 44 and the other stick produces A2.

This is my ram going to unplugg ram now one sec

That kit is on your board's supported list, I am guessing Z490 Taichi by the pics,
which means it should work with your system fine so if it is not working then
either the RAM is DOA or there is an issue with that socket as I mentioned earlier.
The thing that is throwing me is that it should pop the same code regardless of
which stick is installed if it's this socket that is the issue. It's a bit of a
head scratcher.

Have you tried a single stick (the one that gives the A2 code) in each slot and
see if any slots give you a display?
