Vista64 Not Using All Ram

[icedearth15324]

Hello

For the longest time I was using 8gb of pc6400 ram. Well I just decided to bump up my memory to pc8500. However, for some reason Windows is only allowing me to use 3gb of my ram instead of the full 4gb. Anyone have an idea why?

This is what system information says:

I can not figure out why it is doing this. And it is really getting frustrating.

Any information would be appreciated.

Your system sees all the installed RAM.
All I can think of is that you may have a "Memory Remap" function in the BIOS that needs to be enabled. If so it's in the Northbridge section, and this will remap any overlapped graphics memory back to the system.
