IT DOESN’T JUST

STOP AT CPUS

You can overclock your memory and

graphics card’s core and memory too.

Most memory kits can have an extra

133MHz added to their stock frequency

without much effort. There are plenty

of guides out there on how to overclock

your graphics card too and it can have a

sizeable impact on game performance.

The CPU ratio can be applied in small increments

to provide 50MHz frequency increases

Overclocking can be done either through Ryzen
Master software or the EFI
