Windows 7: Windows 7 Ultimate 64-bit doesn't support 4GB RAM?

I realize hardware is an issue here because it's not happening to everyone, but why then does XP64 run perfectly with the same hardware? That leads me to believe that there is a software issue as well. As I've read, there seemed to be a similar problem with Vista that was patched later.

EDIT: And yes, I am also installing W7 Ultimate.

Windows 7 apparently has issues with some hardware configurations and/or BIOS settings. It is either going to take updates from Microsoft or updates from the manufacturers to fix this problem.

Yes Vista had similar issues before, and updates were released to address some of the problems very similar to this one.

Seems to me that using the bios voltage adjustments will fix these types of problems. Those voltage adjustments are there for a reason and this is one of the reasons they are there.

Windows 7 is famous for requiring more North Bridge "memory controller" voltage than XP or Vista in order to run stable. This fact has already been confirmed on numerous occasions. Making sure that the memory voltage is up to manufacture specs will also help.

Learn how to adjust these types of settings people, they can make a huge difference in overall stablity.

A BIOS update may be cure all for this problem.

Now you're getting over my head. Where can I find a good tutorial? I don't want to go burning my board up.
