Ripjaws F3-17000CL9D-8GBXM + ASUS P8Z77-V+ Intel i5 3570k

[kosbar]

Hello I bought this kit Ripjaws and I have a problem to make them work. My MB is ASUS P8Z77-V and the problem occurs when I try to boot with the dimms placed to work in dual channel . MB has A1,A2,B1,B2 slots . When I place the dimms in A1,B1 slot or A2,B2 the red light that asus have for the memory problem stays on and the system wont boot. Everything is ok when I place one dimm only (checked them both) . The system starts as expexted at 2133 speed and 1.65V with one dimm . When I put them in A1,A2 slots (not working as dual channel) the system also boots as expected . So is it a hardware combination conflict problem or sthg else?
I have enabled XMP mode with all combinations .
I have updated to the latest bios .
I tried everything several times before sending this .
Please advise !!!!! Thanks in advance .

Try setting the sticks up, just enable XMP, select profile 1...then try raising the VCCSA voltage to 1.2 ....and then try booting
