This computer has a ASUS P4P800 mobo with 2Gig of ram (4x500M). Memtest failed within minutes. I then ran each memory module one at a time and each ran without failures no matter which socket it was in. Further tests showed that memory tests failed only when I had 2 or 4 modules configured as dual channel *. The system is now running flawless with 3 modules (1.5G) installed which forces single channel operation. Again, the 3 modules can be in any sockets. Since the computer is about 4 years old I am not sure if I want to invest any additional $$ into it but I would suspect either the mother board or CPU as the culprit. I will be willing to test any ideas anyone has but I guess we can close this out as another strange effect of memory.
