RAM fails to function at XMP 3200MHz

Hello!
New build details are as follows:
1) AMD Ryzen 5 2400G
2) G.Skill F4-3200C16D-16GVKB (2x8GB)
3) Asrock B450M PRO4
4) Samsung EVO SSD
5) Windows 10 64bit genuine
RAM is connected in slots A2 and B2.
Power supply is Corsair CX550.

I attempted to apply the XMP 2.0 profile for 3200MHz, but the system fails with a "Video TDR Error atikmpag.sys". Many users face similar issues, so I suspect the 3200MHz speed isn’t officially supported by this motherboard. I gradually reduced the RAM speed and now it runs smoothly at XMP 2.0 @2933MHz.

I purchased RAM capable of 3200MHz to boost performance for gaming and noticed a noticeable drop in speed when the memory slowed down.
Additionally, there are limited options for this motherboard to support 16GB RAM at that frequency.

I updated the UEFI to version P1.50 but didn’t see any improvements.
Do I have a motherboard that can’t work with my RAM? Could future BIOS updates make it compatible? Should I consider replacing the RAM sticks—even if they aren’t available locally—or possibly the motherboard itself?

Thank you!

xmp may not function properly since it is an Intel standard.
Because of the design variations between and Intel's version, you might encounter problems. You could attempt adjusting the timings yourself manually.

This tool can help calculate the timing.

2933 is typical for your setup. You could reach 3200 by boosting the CPU and tweaking clock speeds and voltage for the RAM. It isn't always simple to just enable XMP in an overclock mode. For games, it's best to invest in a graphics card.

B450M Pro4 AMD Ryzen CPUs (Raven Ridge) work with DDR4 3200+(OC) memory, which is not ECC and un-buffered. The 3200(OC) means overclocking is required to reach that speed. I recommend checking out other users' guides on overclocking a 2400G.

Hey, thanks for the updates!
I attempted to use the dram calculator but wasn't sure what inputs to enter, so I couldn't proceed.
I also tried the settings mentioned in the article that Calvin7 shared, but it didn't work either.
I'm still experiencing a video TDR error with the CPU at 3900MHz, 1.475V and RAM at 3200 XMP 2.0.
I loaded the non OCd CPU profile with RAM at 2933, which was the last stable configuration.
I'm not sure what else I should try—maybe wait for a future BIOS update to support a default 3200MHz RAM setting?
Appreciate the help again!

I also asked Asrock and just got an email from them. I thought it would be useful to share it here so others might find assistance. (It seems I attempted their recommendations without success.)
I’m unsure what the AGESA code refers to, but I tried the suggested settings, but nothing changed. The only thing that remains stable is the RAM speed at 2933MHz.
