Hum... some motherboards allow to enable what is called "memory
remapping" that "returns" to the OS all the available ram memory used for
AGP or PCI devices.... well, sort of :-)
You have to look for that option in your BIOS, but notice that is not
always present (look also for any BIOS update that add this capability or
ask directly to Asus).
