Ram not running at specified speed

[Rimi]

Hi guys, I just built my first PC and noticed this issue described in the title.

 

I have DDR4-2666 Corsair Vengeance LED 16Gb as Ram but according to the Bios they,are only running at 2133Mhz.

 

I have the MSI b350 pc mate mobo. How can I run the RAM at their given speed?

You need to overclock the RAM to to reach the RAM's tested speed. 2133 is default.

Check your motherboard QVL to see what speed your RAM has been validated to run at on your motherboard.

UEFI/Bios will show the XMP Profiles (at least for Intel boards, not sure about Ryzen) that'll let you clock the ram at the rated speed (or maybe a setting or two beyond the rating on the label (eg: 2400MHz on label, 2666MHz XMP setting that is stable), depending on the RAM).
