Probably I found cause of issue: it is some kind of oil from thermal pad, it leak on mobo over chipset: http://forum.ixbt.com/post.cgi?id=attach:9:68823:5110:1.jpg

I remove it and looks like mobo works fine now.
Same crap probably with Fatal1ty X370 Gaming K4, X370 Killer SLI, Fatal1ty X370 Gaming X and other mobo with near design.

I unscrewed the two screws.
I took off the radiator.
Wiped with an alcoholic napkin.
Wiped with a dry rag.
Installed a new thermal pad, screwed the radiator.

So the oil-like substance, that was apparently conductive, and on or contained within the thermal pad from the factory was shorting some contacts on the chipset or components around the chipset? Or do you have another explanation?

That is very unusual and I'm sorry if this was the problem.

Regarding other models of AM4 boards experiencing the same thing, I have an X370 Killer SLI/ac, and have never had a problem such as you did.

Whether the thermal pad was supplied with the chipset heatsink from its factory, or if the thermal pad was added at the ASRock factory, any contamination or defect in the thermal pad would occur randomly, by chance.

Finding this as you did was an amazing thing, the vast majority of people would have never noticed this. I don't know if I would have found it.

I think thermal pads may be part-to-part different.
At least one man wrote at russian forum about his Gaming K4 and oil from thermal pad.
I check mine Gaming X and see same oil. (thermal pad was small and does not cover all chipset)
Then I check mine AB350M Pro4 and it was OK: no thermal pad on chipset and I dont see oil on VRM.
At last I disassemble taichi and see many oil at chipset and around chipset. (Taichi my oldest mobo)
I remove oil and run one test with bristol ridge that always reboot on mobo. And get no reboot.
In theory there may be some mechanical defect with taichi, like bad contact some where, that was self fixed while me "play" with mobos cooling system.

I can share photos how I modify cooling system on my mobos.
Oil, small thermal pads, bad radiator form (K4, gaming x) - all on photos.

Very near design mobo (Gaming X...Killer SLI...).

(But AB350M Pro4 does not have thermal pad on chipset, at least mine)
