I built myself a pc long while ago, and as I'm learning more and more, I see that my ram is only running at 2133mhz.

I went into the "MSI Click Bios 5" and changed the setting to A-XMP profile 1, and set DRAM frequency to 3000mhz. Then the pc wouldn't post. So I had to reset the BIOS and boot up again.

Any help would be appreciated.
