Probably the best place for you to get an answer is Gskill forums. That is their specialty.

Try setting VCCIO Voltage to 1.15v!

I have the CL7 version of the 4GB Modules (x4) and had a lot of issues with them and seems many do!

They don't guarantee two sets will work as it is harder to get some high performance ram to work as a set of 4.

Did you keep the sets as matched pairs? i.e. pair from first pack in red slots, pair from second pack in black slots.

The pairs are matched.. i.e. they could have the same model number but be 5 or 10% different from a pair in the next pack.

If you did keep them together then try swapping slots.. i.e. move the pair you put in red to black and visa versa. The board may then use a different pair to set values and you might get lucky.

That is all BS marketing!

This motherboard is dual channel so only 2 slots are twinned! (unlike the X79), so long as the sticks are same revision and have exact same timings it will not matter one bit!

Peeps even run non matched single sticks!

Go over to their forums ans see many peeps get issues with their memory on this Mobo esp the tighter timings models!
