Ryzen 3000 series support

I went from 2400g to 3600 on the b450 itx. Stable as a rock booting with 2400g.

3600 has never been stable in boot.

Tried all bios upto 3.50

The support is not getting tired to point at my PSU or talking about a defective CPU. The first is a one year old Corsair SF600 which worked perfectly with an overclocked Ryzen R7 1700, the latter is something I never experienced in 30 years of hardware. Fact is: I can always get the board to cold boot/post after pulling out the cable, wait 10 seconds and put it in again. What does never work is, making a warm boot or starting without pulling the cable. When the system has started, everything works perfectly stable. The only issue is starting and sleep mode.

And you never had this issue with the 1700 and the same motherboard, gpu, psu, etc right?

I only tried a Ryzen 1600 for a week, I haven't had any issues as far as I remember, but 1 week was not enough to know that the 1600 was perfectly stable with the B450 ITX, and the 3700X not.

I hope it is solved soon... (3700X here but same motherboard).

Support recommended me to try with another PSU. But buying and replacing the PSU is a pain in the ass, and with so many people facing exactly the same issue with the same motherboard and Zen 2, then I don't think this is the problem. I think it's either the AGESA bios running with 4XX chipset OR something that needs to be figured out by ASRock in their firmwares (but I think this issue we have, is present also in some MSI boards as well).
(PSU is working fine, PC never crashes no matter the power I draw. And it's not old).

The new stuff in my rig is:
- 3700X
- B450 ITX motherboard
- RAM: BLS2K8G4D32AESTK
- and the NVME Crucial P1

All the rest is harwdware i was perfectly using before. From the new stuff, the NVME is not an issue, if I remove it, issue persist.

There seems to be a BETA bios for X370 Gaming K4 over at JZ electronic available, check the link in the OP. Includes 1003ABB AGESA.

I recently upgraded from the 1600 and expected a smooth transition. Knowing that this board is now 2 generations old, I expected ASRock to devote little resources seeing as the newer generations are more pressing, and they would like to push folks like me into upgrading to their new X570 line. But seeing many older gen board receive their beta BIOS??I begin to wonder exactly what is their plan for the X370 Taichi owners? I refuse to bring disparaging comments against a company that has made products that have served me so well in the past. I simply am wondering if I am better off upgrading to the x570 Taichi so that I can run at a memory speed greater than 2133? Any suggestions?

If you look at this thread:

https://www.overclock.net/forum/11-amd-motherboards/1627407-asrock-x370-taichi-overclocking-thread.html

you can find 9 new bioses with AGESA 1003 (from 5.60 to 5.67 and 5.80 which seems to be the almost official release). Don't ask me why ASRock don't publish them on his site.
