AMD Ryzen 3600x with Fatal1ty X470 Gaming-ITX/ac

Is anyone manage to get it working?
Have my bios updated to 3.30
Check that everything works with my old 2700

put 3600x it boots to a bios(after a few boot cycles) I see the ram drop to 2400 so I update to 3200(as that one that I have)
Didnt have a single successful boot after, just power cycling with fan spins and stops.
Tried:
clear CMOS - nothing
wait - nothing
remove one or all ram - nothing

Any ideas?

After it POSTs again, go to BIOS and drop the memory to 2133MHz. On mine it only POSTs consistently at 2133MHz. Anything beyond 2133MHz won't even POST every time.

Have you had to clear CMOS? I tried to wait maybe 30min. I will try longer, thank you for bringing hope!

I'm also having issues with the B450 variant of the ITX board and a 3600x, doesn't POST, fans spin for about 20 secs and then restarts itself. I hope this is relevant enough to piggyback on your thread.

This is a new build, so has an old BIOS v1.30. I can't get it to POST, I've breadboarded it, tried putting RAM in different single configurations with both sticks, cleared CMOS several times, removed CMOS battery overnight, reseated all components multiple times, tried another known-good PSU, my GPU is known-good, I've let it try and cycle for hours without any change.

I suspect now from this thread that my RAM is the issue.

- ASRock B450 ITX Fatal1ty
- AMD 3600x
- Ballistix DDR4 3200 16GB (8x2)
- NVidia GTX 1070
- Corsair SFX600 PSU
- Sabrent 512GB Rocket m.2 SSD

I submitted a support request via this site but haven't heard back yet. I am trying to track down some DDR4 2133 RAM to see if I can get it to POST at least and then update the BIOS to see if I can get it then to POST with my 3200.

My BIOS is so old I don't even know if it supports the 3600x at all. What I had read elsewhere was that older boards would at least provide minimal capabilities until the "compatible" BIOS update was applied, but maybe not. I don't have any previous gen AM4 chips I can swap in if that isn't the case...

Well that doesn't sound good for any of us. I bought my board a couple months ago when it was on sale, so can't return it. Anyone who can, probably should. I may just cut my losses and buy a Gigabyte or Asus board instead and try and sell this one on Ebay.

That, at least in my case, is a good sign, because usually when this happens, I just have to force-reboot only once by long-pressing power button to see the POST screen again. I later realized if I drop the memory down to 2133MHz immediately at this point, the board will start to POST consistently and the issue is mostly gone. Hope a future revision of BIOS would fix it.

tried for a few hours unable to get to POST at all. on other hand when i put my old 2700 it starts and works perfectly :(
not sure shall I return CPU and wait or swam motherboard.
One of the reason for buying x470 in hope for better support 3000x series - well that clearly didn't workout
