What's going on?

RAM compatibility is tricky as hell and contrary to popular belief, has very
little to do with the motherboard. The key elements are the RAM itself and the
IMC on the CPU. Where we see motherboard manufacturers "adding" support what we
are really seeing are tweaks to the timings, voltage and other settings that
get added in to the UEFI for a particular RAM model. AMD adds offsets and such
to the AGESA code for the same reasons, to ensure more broad RAM support. There
is absolutely no reason you can't do this yourself with some patience and the
correct software.

XMP is not a standardized thing nor is it the RAM's default settings. It is,
pure and simple, an overclock profile saved to the RAM's firmware and just like
any overclock, it is not guaranteed to work on all possible configs. RAM
manufacturers do their best to make sure the XMP profile works on as many
configs as possible but this has to be done within reason, there are just too
many possible hardware combinations to test them all.

In essence, if your board POSTs and boots into the OS without issues and is
stable at 2133 (or 2400 or 2666 depending on the rated speed of the IMC) the board is not the problem, the XMP profile that won't run
stable is. Typically a setting or combination of settings are too aggressive or
the voltage isn't high enough. My 3600 kit wouldn't even run at 3200 (XMP set
then frequency lowered to 3200) on my 1600x with the BIOS the board came with
but once I went in and manually set it up based on info from tools like Ryzen
calculator and thaiphoon burner I was able to get it stable at 3400, 3533 was
stable except for one game which would randomly crash.

Ryzen Calculator
Thaiphoon Burner

These tools are exceedingly useful in setting up your RAM frequency and timings.

I had the same thing with my b450ITX/ac Fatality with 3.50 (latest non-Beta for this board). Stripped it down to nothing, and discovered it was the M.2 drive.

I lost the M.2 boot from previous BIOS update to support Ryzen 3K, however I could at least still access it from the OS. With the most recent, I physically had to remove it from the system to access the BIOS. (currently booting from SATA). Luckily, I was able to migrate everything over, prior to this "update" so I didn't lose any data.

I could access instant flash, and boot order (m.2 drive not listed) at boot. But F2/DEL lead to black screen with frozen old school cursor bar. Hard reset required.

A quick follow up on my issue with UEFI BIOS hang in 3.50 for B450AC-ITX with M.2 drive attached. The offending M.2 drive was a SATA/AHCI drive (Samsung OEM). I came into a free NVMe drive, and everything works fine.

Anyone have the b450 itx bios 3.51 link? Support has responded for a few days, and I am having serious boot loop problems like many others, can barley get into bios. Probably takes about 30-40 tries.

But I am running that bios, and still the same problems after 2 reboots.

Power cycling is most often caused by RAM training and repeat failures to POST.
If you are getting power cycling at 2133 then either your RAM is woefully
incompatible (with the AGESA/BIOS version on your board) or there is a different
issue at play, such as poor power quality/low power. Ryzen has made
troubleshooting problematic as so many issues stem from RAM compatibility and
often times it leads us down a path related to RAM when in fact the issue is
elsewhere.

As for RAM support on different brands of board, bare in mind that every
motherboard brand has relationships with RAM manufacturers, different
relationships for different board manufacturers. Most often it isn't a case of
better or worse overall support but more a case of better support for particular
RAM brands depending on the board manufacturer.

@xaltar
Any idea why the Asrock x570 itx board pulls a lot more power than the gigabyte x570 itx?
According to the Tomshardware review on load and on average, the asrock board is using significantly more power
Load (prime95): Asrock 211W vs Gigabyte 142W
Avg: Asrock 138W vs Gigabyte 106W
https://www.tomshardware.com/reviews/asrock-x570-phantom-gaming-itx-tb3-motherboard,6293-4.html

Can this be remedied with bios updates or changes in bios settings, or is it an issue with hardware?

I just ordered one for tb3, but I may have to return it if there is such a significant difference in power draw/efficiency

Yeah, minimal power differences are hardcore, I'd definitely return it....
REALLY?
Have at it, ya'll worry about things that are minimal.....
If 36 Cents a month matters THAT much, have at it.
