Memory Blue Screen Problem

[cassiusuk]

SPECS- "Dell dimension 9150, 1.5 gig ddr2, pentium d 940 3.2 mboard socket 775(i think)" :beer:

Hi I recently bought a nvidia 7900 gs fitted it in the pci slot. I also fitted 2 512 memory sticks of ddr2 memory from kingston. I had alot of trouble fitting the final one in the final slot(I have four mem slots on my motherboard).


It did eventually fit but didnt seem right, seemed to tight. When I rebooted it was fine, but every now and then when the computer had to reset a blue screen came up before windows started.(IT DID RECOGNISE THE MEMORY IN SYSTEM PROPS HOWEVER)


When I reset again it was fine. I have since removed that memory and it runs fine. What should I do, is it the memory or motherboard, somebody said I am losing perfrmance but not dual channeling?, i have 4 slots, 3 with 512 in the last one empty, please help. :bang head

You are losing performance by not running in dual channel mode. I would run the 2 new sticks in dual channel and see if the BSOD keeps coming back. I would also suggest running Memtest 86+ to see if the memory is bad out of the box.

You have several potential issues working against you. First, you ONLY need to add OEM type memory to a Dell machine. I would suggest getting it from Dell or, a manufacturer that makes memory for OEM systems. I can recommend some if you care to ask.

Also, when you mix and match memory, you may mix types that are not compatible. And, as mentioned above, you need to use either 2 DIMMs or 4 DIMMs so that you stay in dual channel mode.

Also, you may want to check with Dell and be sure your power supply is up for the added load of that video card. What card was in the machine originally?
