ASRock X570 Taichi RAM issues

   Hi muziqaz, thanks for the reply

I used flashback to flash 4.0 because that's what I understood from the BIOS support page on ASRock site 

*If you use Pinnacle Ridge or Picasso, please use ASRock Flashback function to update this BIOS. 

I had the 2700X at that time so being Pinnacle Ridge that's why I flash it.

Then I removed the 2700X, put the 5950X and it didn't start, so I flashed with flashBack the 3.40.

Regardless, I followed your advice and strated updating the BIOS version by version with clear CMOS between for each.

3.40 -> 3.60 OK
3.60 -> 3.61 OK
3.61 -> 3.80 NOT OK

The system kept restarting on it's own, no boot, no BIOS. Error on the motherboard 0d.

Searched a bit over 0d and found

0d     Problem related to memory, VGA card or other devices. Please clear CMOS, re-install the memory and VGA card, and remove other USB, PCI devices.

I will try to remove the memory from slot B in order to install the BIOS but I don't think this is the issue here as it worked with the 2700X on 4.0 Version.

Do you have other suggestions?
Thanks!

	Flashback should only be used if you have no supporting CPU to be able to use Instant Flash utility in BIOS. Flashback feature can flash to older BIOS even without CPUs or other things installed. You can now flash newer BIOS version one by one until you reach the latest version. Do not use Flashback for that. Use normal BIOS methods. Don't forget to reset the BIOS to default after each flash

	Moreover, after taking a look over the info in Windows, through CPU-Z and NZXT CAM, it seems that the motherboard is aware of all 4 RAM sticks but somehow the don't work

	Hello all, I've recently bought a ASRock X570 Taichi and a AMD Ryzen 5950X to upgrade my previous setup an ASRock X470 Taichi & AMD Ryzen 2700X. The RAM I used the ones I had before, 4x GSkill FlareX for AMD DDR4 @3200MHZ When I tried to boot up the new rig it kept restarting. After reading a bit, the problem was the BIOS version, that it didn't support the CPU. Put the 2700X in the rig, booted up. Updated the BIOS to 4.0 (via FlashBack), booted up with the 2700X, with the 5950X kept restarting. I've downgraded the BIOS to 3.40 (via FlashBack) and the rig booted up with the 5950X as well. The problem that I have now, it's that my PC recognizes only the RAM installed in the A1 and A2 slots and the ones from B1 and B2 not. Tried to switch them between them and nothing changed. Should I update the BIOS to another version? Which version should be ok for the CPU as well? Is there something else that I should look at?
