How to enable XMP profile on ROG STRIX B360-F gaming

In motherboard bios... Go to xmp select it.. And it will show two profiles.... Profile#1 and profile #2

Select the first one, save and your pc will restart... And xmp will be successfully enabled
 


 
G.SKILL Ripjaws 4 Series 8GB (2 x 4GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000) Memory Kit Model F4-2133C15D-8GRR




 
It's DDR4 2133. It will run at its rated speed when you plug it in. It doesn't have any XMP profiles associated with it since basic, default DDR4 is always 2133. So the RAM doesn't have any XMP profiles to load.
 
DRAM Freq. 1064.9 NB freq. 3790.7

so is it running at 2133?





 
Yep. DDR = double data rate. It sends information on both the rising and falling edges of the clock cycle. RAM is sold at the effective speed not the actual speed. Programs like CPU-Z read the actual speed and you have to double that for the effective speed. My DDR4 3200 reads as 1600 in CPU-Z etc.

DDR4 defaults at 2133. You'd have to underclock to go slower.
 
You wouldn't want it to go slower, right? So my RAM is ok, great. Thanks
