Bad Ram? Mobo?

[Zanghor]

Ram: 2x2GB Geil Dual Channel DDR2 800 = 4GB
Mobo: EVGA 122-CK-NF68-AR NF680I 775

My issue is that Windows will boot up when I only have one stick of ram in at a time. I have tried each of them seperately and they both work. When I try to put them in as dual channel windows does not boot. I have tried both combinations of dual channel slots.

Help is appreciated.

and how can I test the ram or mobo?

Ok, If i put both of the ram sticks in my mobo, but NOT in dual channel it works but it only registers as 2.75GBs.... what gives?

If your booting XP, it has a problem with 4 gigs of ram. This is why you see so many ppl with top of the line systems and only 2 gigs of ram
