Yes you are correct .I used 2 sticks ,2 gb each. (Cosair XMS2 / CM2X2048C5 800mhz)
I took one to best Buy to get two more like it and they gave me instead, 2 Cosair Gaming Memory 2mb sticks (CGM2x2G800)
and said they would be compatible/ equivalent to the XMS2's.
It said on the motherboard manual (Gigabyte GA-P35-DS3L Rev 2.0) that as long as to pairs were the same type and brand they should work/ The boot up shows the 8mb , but when windows starts (if I don't get a black screen that hangs first)
The "Windows Starting" page just hangs forever.
I think my system doesnt like the "Gaming" memory, or they could be defective. I tried all four Ram slots and they only work with the 2 XMS2 DDR-2's. I have them in right now as I'm typing this using Windows & Pro on the computer I'm having trouble with. I tried the 2 gamo\ing sticks together by themselves and the bois wouldn't even come up.
So is it bad ram, and can I return them (they're only 2 days old) or do I have to take the loss and just buy the same type of ram and try again?
