Hello, I have Asus P5Q SE motherboard and had 2x1 GBs Kingston DDR2 RAMs. Recently I bought 2x2 GB DDR2 Zeppelin RAMs. The motherboard has four dual channel DIMM slots. Yellow-Black-Yellow-Black. My old rams were in the yellow slots, dual channel. They worked and still work. If I add one or both of the Zeppelins into black slots, it just BSODs on startup. BIOS shows the correct RAM memory in any configuration, but Windows 7 64bit BSODs.
I tried all configurations from which:
Two zeppelins Yellow-Black: Windows starts
Two Kingstons Yellow-Black: Windows starts
Two kingstons Yellow-Yellow: Windows starts
In any other configuration the Windows BSODs on startup.
Currently Iam running two zeppelins singe channel but Id like to run all 6GBs.
