Pop into the BIOS and change the memory multiplier or see if there is XMP option.
To what? Sorry, I'm a novice with this stuff.
Yeah its what you use to set the ram speed,its perfectly normal,see where it says 1333mhz? You want it to read 1600mhz
Or you can enable xmp and pick the 1600mhz profile
Just change the top setting to enabled
