Well it should work, but generally the 3900X is kinda designed for the X570X boards, in which some want 8pin+4pin CPU power cord to be plugged in to work, and some others want and have 2x 8pin CPU rails and want both to be populated to deliver enough power, but if you ask me what I think I believe it is more BIOS related for none X570 boards. I personally know how much power can the 3900X use, and personally I would buy an X570 MB with some 14-15 power phase design and not from ASRock and not from MSI, only ASUS or Gigabyte.

I will keep my good old Fatal1ty X370 Pro Gaming with the 2700X.

And for the 3900X:
I do not like the X570 boards with this bad placement of the chipset/fan nearby the GPU, all M2 slots covered with one big plate or bad placed USB 3.2 Gen2 Header.
I think we will see new boards/revisions from nearly all vendors next year.

There is not much left for choosing today... NAAA (No A at all)

I had no problem getting my 3600 working in my X370 Gaming K4 or my X370
Taichi. I updated to the latest BIOS (at the time) and just swapped it in. I
think there was about 45 seconds of power cycling before I finally got POST but
after that all was well. I actually had less problems with my X370 boards than
my X570 Taichi though I suspect my RAM does not play nice with X570. Don't get
me wrong, my X570 Taichi works well, it just won't wake from sleep. It restarts
instead then power cycles until defaults are loaded. Not a huge issue for me as
I don't use sleep but still, it isn't a problem on either of my X370 boards.

It could just be that the 3900x is more demanding on the board as SKYPREDA7OR
noted. I believe reviewers got the 3900x working on an A320 board though so who
knows. I did have to clear CMOS via battery removal to get my 3600 working on
my X370 boards, if you haven't already tried that it may be worth a shot.

I found a semi consistent method to boot my system.
I only consider this temporary until Asrock finally fixes these boot loops.

When turned off also keep the PSU switch off.

  1. Turn on monitor (connected via DVI to GPU) and wireless mouse.

  2. Push power button.

  3. If the fans don't start spinning within ~5 seconds (which indicates that it will POST for me), turn off PC by holding power button for 5 seconds.

  4. Push power button again and repeat 3. until it posts within ~5 seconds.



Usually it only takes 2-3 attempts to boot and it doesn't forget Uefi settings that way! Not sure how long this will last. Maybe it will break again tomorrow...

System:
Asrock B450 ITX
Ryzen 3600
Crucial Ballistix Sport LT 16GB/CL16/3600Mhz(BLS2K8G4D32AESCK)
Sapphire Pulse RX590

I had a similar problem on cold start some times ago.
I resolved that by disable fast startup on windows shutdown.
I think, this was enabled within a windows update.

I have this always disabled and checked if it stayed disabled after recent updates.

It's not a windows issues because even if you remove power from the system, these boot loops can occur.

Ok, problems are different. But my bios startup problem also and only occured after switching on the PSU and mobo power botton, cold start.
A second longer push to the power botton or reset did the restart and the system came up. However, i was surprised, that this windows thing can influence the bios cold startup behavior.

I got a 3700X and a B450 ITX motherboard and If I run a Prime95 (maximum power variant) I get an error in less than 60 seconds.
Meaning that the CPU is not 100% stable.

Anyone with a 3700X and a B450 could try this? It could be the BIOS or it could be the CPU. (The RAM seems stable. I can run memtest without issues).

I'll wait for AGESA 1.0.0.4 before taking a decision (like sending the CPU to AMD, or trying a new motherboard).
MB: ASRock B450 ITX (P3.70)
CPU: Ryzen 7 3700X
RAM: Ballistix BLS2K8G4D32AESTK
SSD: Crucial P1 500 NVME
GPU: Gigabyte G1 GTX1080
PSU: Enermax ERX530AWT --> Corsair RM650x (CP-9020178)

@sebastianer: Everything on stock?
What about CPU voltage and temperature(s)?
