ASRock x370 Taichi and ryzen R9 3900x , error code

I installed ryzen 9 3900x and now the motherboard began to load longer, on the error indicator such numbers 27, 33, 99, 98, 62 appear. In first system start cpu cooler didn't work few seconds, it's ok?
was made ?lear cmos. This has not changed anything. Clear cmos was made with a side panel and on board with a jumper. any difference.

Bios 5.60. Before was instaled ryzen 7 1700.

Windows work well and linux. Don't have any issue in OS but in aida spd dont showing, in cpu-z its showing. Gaming, modeling, rendering and synthetic test work well, if reboot system, motherboard make pause before load bios with showing codes. With ryzen 7 1700 don't have this issue.

What could be the problem? Could this problem be an even bigger problem in future and damage component parts?

Updated the bios. All the same. Error codes 27, 33, 60, 62, 99, 98 and others. I decided to ignore this problem. Everything was ok, but recently, the computer has stopped turning on. Coolers spin, LEDs are on, but pc not turned on. It was 2 times. If re-install video card to other slot, system can start up with same errors but everything work.

How can know about new bios. or what can help with this? Or asrock taichi x370 cannot correctly run with ryzen r9 3900x

p.s.
im on bios 5.8 seems the most stable for x370 taichi

Hi R_two ,

WoW, I experience everything you wrote above, 100% exactly same, including my old 1700x no symptom.

Firstly I hope I'm right, I want to say Dr Debug shows 27, 33, 99, 98, 62 is no problem at all. These are good numbers for Zen-2.

If you see 33,7a,3b,b6 then problem.

or if you see A0 and stagnant no movement then problem.

After clear cmos, first time boot always slow, 3 boot something to do with more diagnostics, probably memory training etc, after that future boot is fast.
