I got 3 new RAM Modules (CSX 4GB DDR3 1333MHz) if I insert one Module into my ASUS Z8NA-D6 Board the Computer starts. But if I insert a second or third one the Computer wont start. Next I run a memtest for each module but all works fine for one Module.
The Board has a triple Chanel Controller and DDR3 RAM is dual Chanel but it doesent matter I think?
What I do wrong?
