I thought that too, but it doesn't seem to be the case.

Today I had a little time so I did some test to rule out any possibility of faulty hardware.

TEST 1

CPU: Ryzen 5950X
MB: X570 Taichi
RAM: A2 Slot & B2 Slot - 8GB GSKill FlareX DDR4@3200Mhz CL14

Result: B2 slot shows empty

TEST 2

CPU: Ryzen 2700X
MB: X570 Taichi
RAM: A2 Slot & B2 Slot - 8GB GSKill FlareX DDR4@3200Mhz CL14

Result: Both slots work fine, 16GB RAM shown in BIOS

TEST 3

CPU: Ryzen 5950X
MB: X470 Taichi
RAM: A1,A2,B1,B2 Slots - 8GB GSKill FlareX DDR4@3200Mhz CL14

Result: All works fine 32GB shown in BIOS

[URL=https://ibb.co/30yBkFy]FULL SIZE IMAGE HERE[/URL]

Both channels work fine on the X570 - tested with the 2700X
The 5950X work fine with all 4 RAM sticks - tested on the X470 Taichi

Why on earth doesn't the 5950X work with channel B RAM on the X570

OK, I'm grasping at straws here, as I ran out of explanations and ideas :D
Put all the sticks in into x570 and 5950x. Boot into BIOS, set the XMP profile. Make sure VDIMM is set to whatever your RAM needs to have (usually 1.35V+). Save BIOS settings and restart into BIOS again. Check if a miracle happened and you see all the sticks (as I said, I'm grasping at straws :D ).
If nothing changes and you still cannot see all the ram, get yourself Memtest86+ put it on USB drive, boot from it, and see how many sticks and how much ram the program sees.
Also, check the amount in Linux (you said you have it installed as well).
In windows, click Start and type MS Config, and press enter. Go to Boot tab, and click on Advanced Options...
Tick Maximum memory and see if it writes 32768, or something like that. If yes, click OK, and OK again, and restart the PC in to Windows again. See if a miracle happened and Windows sees all the ram :D
Now for the final straw:
Use Flashback feature to flash the BIOS to oldest BIOS version which could support 5000 series CPUs, which is 3.40 on taichi.
Then, using USB 2 ports at the back start updating BIOS one by one till you get to the latest (miracle), or PC starts rebooting as before. I know you probably already done this, but I'm looking into exact sequence of the procedure. Use Flashback to get older version, and use normal Instant Flash from USB drive connected to USB port (non blue).
Because you will be flashing back to 5000 series supported BIOS, you won't need to remove 5950x.
If all of that fails and does not bring any progress, best advice would be to RMA the CPU (just because it will be much faster than Asrock RMA of the motherboard). OR if you do not need PCIe 4, just use x470 Taichi :)

Today I tried something else, I removed the RAM sticks left only one on A2, removed the GTX980ti setup an GT710 card, put the 5950X in the X570 and updated the BIOS to 4.00.

All worked, the PC didn't get stuck on a boot loop any more...

The worst part is that if I put a stick of RAM in B2, the PC doesn't start and I get the 0d error pops up on the debug. If I change only the CPU, all works...

So BIOS settings and other related stuff I don't think that they apply as both CPUs use the same settings, one works one not.

For the moment I moved the 5950X on the X470 and next week I will buy another X570 from a different manufacturer to see if the problem is with my 5950X and any X570 or only with this MB...

I have a similar issue,Corsair only works in A2 B2 Gskill only works in A1 B1 I have the 5800x 5.61 bios.Just wierd and definately can get 4 corsairs 3200 to go,but not 4 Gskill.3600 0d no nothing.Try A1 B1 boots.Put Ryzen 7 3700x in everything works.Put everything in x370 msi board all good.Put in B550m prime all good.When it says 0d code you get no screen like the gpu is not working.Like those slots have something to do with APU because I litterally hear the PC windows loading but no picture.Like those ram slots disable the rtx 3060.I litterally can get into windows,just cant see.Must be bios for an APU that is bugged.As they should all be supported with the latest.But here we are.
