So its been months since the problem started. My Motherboard wont boot with 4gb DDR2 (2gb X2) Corsair 800MHz PC6400.
I've switched sticks between slots and individually they work, just not together. I've tried increasing the voltage to my memory and that didn't help at all.
I need some serious help, also should I buy a new motherboard if this can't be fixed? (Im thinking of an EVGA 780i)
Specs:
Coolermaster CM 690
Corsair 650W TX
Intel Core 2 Duo E8400 3.0GHz (no Overclock at the moment)
Asus P5N-D 750i
Corsair DDR2 PC6400 800MHz 4GB (2 only now)
XFX 9800gtx+ 512mb
Hitachi Deskstar 500gb 7200rpm
LG 22x DVD-R/CD

Input devices:
Acer P191w 19inch Monitor
Logitech Mouse & Keyboard
Logitech LS21 Speakers 2.1
D-Link DWA-130 N Wirless Adapter USB 2.0

what are the timings on the ram. if its 4-4-4-12, try setting them to 5-5-5-15 before you stick the other 2 in.

Unless you need a new motherboard I wouldn't buy one. Put in one of the sticks of RAM, boot Windows, and run a program called Memtest. It'll test your RAM and tell you if there is a problem with one of the sticks of RAM so you'll know which to send back. You could also try putting the RAM one stick in each channel and see what happens. If it works then you have a problem with one of the sticks for sure.

shame you didn't read that each stick was tried individually. as for memtest, it doesn't run within windows. it runs off of a live cd. iso can be found here

you will only need one if you so choose to use it.

^+1. Also you can get UBCD which contains Memtest86+ and a lot of other useful tools.
