a couple of months ago I built an entry level C2D system with an Asus P5NSLI and 2 GB of GeIL memory (2x 1GB of DDR2 667, dual channel kit).
The system was plagued by intermittent reboots but I was too busy with the holidays and other things to really use the PC, much less diagnose the problem.
Fast forward to last weekend, I decide its about to time to sort this issue, and figure that a memory issue is the likely culprit and try Windows Memory Diagnostic.
With the RAM installed in Dual Channel configuration (i.e. Bank1,Slot1 + Bank2,Slot1) the system reboots 3/4 of the way through test #5, the "checkerboard pattern" test. No error capture by WMD, just a soft reboot - just like the random reboots I had been experiencing. I tried shifting the memory to B1S2 + B2S2 and got the same result.
Further experimentation showed that both memory modules operated fine by themselves, passing the standard WMD tests, and the worked fine when both were installed single channel configuration (i.e. Bank1, Slot1 + Bank1, Slot2).
Currently my system has running stable with the memory in single channel, but obviously I would like to run Dual Channel to maximize system performance.
Any thoughts on the culprit? Motherboard or Memory?
Any tips or advice appreciated.
