OK so this is my first and build, my laptop died and I needed a pc.

Asrock ab350m pro4 mb
Ryzen 5 2400g apu
Evga 500w psu
Gskills ripjaws v 3200 2x8gb ram
2tb WD HDD
4 fans came with case.


So the problem. I've never had to clock a system so its all new to me but my ram is stuck at 2133 even when I try to clock it. I literally can't play any games that are modern on this system as it sits. Can anyone walk me thru an asrock oc?
