Since Flashing my BIOS..

[dr. sarf]

I flashed my BIOS the other day to prepare fora Phenom install.
I've noticed that windows (Vista x64) now reports only 2.75GB RAM, whereas before it addressed the full 4GB I have.

Loading CPU-Z on memory tab shows 4GB, just wondering why windows isn't?
(4x1GB sticks, have made no hardware changes during the BIOS update).
Hopefully it's not a flakey BIOS that only supports a limited amount of RAM?

Ive had a good look around the BIOS for the memory remapping option and there isn't one there, or it is hiding very well.
Don't say my BIOS update doesnt support this feature so over 25% of my ram is sat doing nothing.
