I need some help passing prime at 2.8Ghz

[marcin12]

I am running my setup perfectly fine at 2.750 (250x11) vcore 1.5v x 1.1%. My current ram is mushkin redline 4000, I set it in the bios very tight. With tight settings ram runs fine at 260mhz.

 

I ran memtest at 255x11 no errors. Although it fails in prime.

 

This the funny part with one stick of memory I can run prime stable at 255x11(255 that the only speed I tested) or even more. Just by adding the other one it will fail prime at that speed. I used two different set of ram and dividers and the same thing happes. Single channel go, dual channel no go

 

I am probably missing something in bios to make it stable in dual channel
