Overclocking RAM

hope it helps or wait for some technically know users here.

You can't overclock RAM because it's limited by the dMA and core chipset that's ROM programmed.

You can overclock a CPU, by changing voltage and clock frequencies in the BIOS. But that's fraught with problems that could overcook it for a major problem and failure. You need to know what you're doing to attempt such a thing.

I used to overclock in the early days and had some successes and failures.

It's now better to upgrade the CPU and MOBO with a newer version for higher speeds with multi core models.
