[SOLVED] 3600 memory showing up as 2133

Mar 10, 2021
Hi all,

I just built my first PC, I'm a complete beginner at this. I have an AMD 3 3200G processor, an ASRock B550M Pro4 motherboard, and have TridentZ Neo DDR4-3600 (8GBx2) sticks installed in my A2 and B2 slots (which I'm told is correct).

Problem is, when I run BIOS, my memory shows up as 2133 MHz. I changed the OV tweaker and XMP setting from auto to XMP 2.0 and changed frequency from auto to DDR4-3600. Voltage is at 1.35.
I click save and exit, it restarts, but still shows up as 2133 in BIOS.

Not sure what I'm doing wrong, but wondering if anyone has encountered this and any recommendations would be greatly appreciated!
