Windows 7 64 bit limited to 4GB

[unfitacorn]

I have just had my new RAM put through my letter box, so with the excitement, I put in all 8GB into my motherboard is is compatible with 12GB. But as soon as the microsoft loading page appeared, it would flash blue and reboot. Whenever I just use 4GB it boots with no problem. I just looked under maximum memory in the boot section of msconfig and its stuck on 4GB. Help please?

That is an odd one, you SURE its 64bit?

have you tried using different combos of RAM with some of them out.

100% it's 64. And what do you mean? Like put them in different slots? It's 2x4GB

Hmmm try each one separately to see what happens.
Reset your mobo too.
