SAME PROBLEM AGAIN! Can't install 6GB on Asus Crosshair IV Formula

I have Asus P7P55D EVO and Intel Core i7 875K
Ram only works in slots B1/B2

Anything that I put on A1, makes the system stop posting

I have OCZ DDR3 1333Mhz and Corsair DDR3 1600Mhz

So I bought Asus Crosshair IV Formula and AMD 1090T


There are actually little lights in this board that stop on RAM, so I know it's the RAM

on this RAM, slots A1/A2 work great

Slot B1 doesn't works, if I put anything on it, it won't even post
Slot B2 doesn't works either, if I put anything on it, it won't even post

So, two boards, different architecture (in fact, one is Intel, another one is AMD)
different RAM manufacturers and RAM speeds

Can I conclude ASUS sucks BIG TIME?
Or what is the problem here?

I have sticks of 2GB of RAM

Check what are the voltages recommended by the RAM manufacturers, if they're different (say 1.5 and 1.65 volts) the sticks won't work together no matter what mobo you have. I would get rid of the OCZ and get two more Corsair same model.
