I am not too sure how true it is, but I have heard that some 4GB modules work on this board, meaning that you can have 8GB from only 2 DIMMs!
Can anyone confirm this?

I am thinking of replacing my RAM as I am not 100% sure, but I think it is becoming defective as CAS7 is no longer stable... not even @ 1333Mhz when these sticks are rated for CL7 @ 1600Mhz!
