Hey dudes.

So I recently upgraded to 2 x 2GB of DDR2.

I was running Vista x86, and it only recognized 3.something GB of RAM, which was expected.

So I spent like a couple of days installing Vista x64 and reinstalling all my applications.

But guess what? Still just 3325MB of RAM show up in Windows. The BIOS recognizes all 4GB.

How can I get the rest of the RAM to show up?

Here are some pics that might help:

You need a newer motherboard that supports memory remapping.
