I've just built the following:

730W Be Quiet! BN183
128GB Corsair Performance Pro
Core i7 2600K
4x 4GB Corsair XMS3 1333MHz
Asus P8Z68-V GEN 3

It boots fine with RAM in the left hand slots, but as soon as I add anything in the right side, whether it's one stick or two, it refuses to boot - no screen output & the RAM/Mem-OK red LED is on solid.

I tried pressing the Mem-OK button, it flashed for a bit, but then went back to solid.

As above, it boots absolutely fine with memory only in the left hand slot.

I have tried different sticks / combinations in the right (1 stick on its own etc), nothing will work :(

I have also booted, set the XMP profile, voltages, etc., then stuck the rest of the RAM in, but no luck.

I'm using the stock 2600K cooler which went in nicely, so I doubt it'd warped or anything like that.

Any ideas?

Thanks.

Only use the left side memory channels then update the bios on the motherboard and try again o and make sure the ram timings and voltage are at the correct level's (for the ram) then turn it off stick in 4, if it still dosent work then rma it!
I once had a problem like this and all it was a memory fix via bios update!
 
Will try motherboard update tomorrow, one of the later releases improves DRAM compatibility, although I'm not sure what version it actually has. Will check in the morning.

Thanks for the suggestions :)
