Could my memory controller be at fault? (I7 3770)

[idata]

I made a build with an Asrock Z77 Extreme4 motherboard and a 2x4 kit of Corsair Vengeance 1600 1.5v (CMZ12GX3M3A1600C9).

Each stick works perfectly fine by themselves in any of the slots, but when I try to use both (in any combination, dual or single channel) I get a lot of errors in memtest86+ and BSODs.

I've been searching google for an answer since last week and one of the possibilities I've been led to believe is that it might be a problem with the memory controller in the CPU. Could anyone help me narrow this down?

Thank you.
