Memory is not stable with XMP enabled!

[RichardH754]

Hi, my G-Skill Ripjaws 1866 ram wont run at its xmp profile stable!

As soon as I start playing a game it crashes

Its fine at 1600 with tighter timings

I wonder if I have a bad stick??

I have tried a slight voltage increase but it still does it.

XMP is 1.5v
