Ryzen 3 2200G support 3000 Mhz ram?

[fer7]

In offical AMD website write Ryzen support only System Memory Specification
"2993MHz"..

mobo: ASRock AB350M Pro4
ram: Kingston HyperX Predator CL16, HX432C16PB3K2/8

Yes it does support more than 2933MHz RAM bt that's also a question for MB, it's BIOS and if it supports more (OC or XMP).

Thank you so much!

It says 2933MHz instead of 3000 because in Ryzen MBs they don't run BCLK/FSB at full 100MHz but in 99.5 - 99.8 range.

Except that makes no sense....

how does 99.5Mhz BCLK * 15 multiplier for 3000Mt/s * 2 because it's DDR = 2933? do the math for 99.8 and it's even further off.

I agree AM4 motherboards seem to universally understate BCLK but 2933Mt/s is a valid memory data rate too: I can set memory to 2933 so that (100 Mhz theoretical BCLK * 14.665 multiplier * 2 because it's DDR) = 2933 Mt/s. Although, it will probably be more like (99.5 Mhz actual BCLK * 14.665 * 2) = 2918Mt/s. In the same way, setting it for 3000 will actually get (99.5*15*2)=2985Mt/s.

Just trying to understand that statement.
