G.Skill Unstable at 2800 XMP

I have the 64gb single kit of G.Skill Ripjaws 4 2800. Setting the XMP in the bios works but the ram becomes unstable after a short time in Windows 8.1. After running Memtest it throws out errors on the first test which is related to cpu. I am running my 5960x at stock. The XMP sets the frequency, bclck and strap it appears and leaves the rest on auto. Is there some voltage or something I should be bumping up to make it stable?

It passes fine on Memtest at the default 2133 and all on Auto.

Thanks

The motherboard automatically assigns a value for your CPU. You can use that as a starting point and increase it with intervals of 0.01V.
