So i have Vista Home Premium x64. I have 2 X 2 Gigs of Patriot DDR2 (800)
and 2 X 1 Gigs of Patriot DDR 2 (800) for a total of 6 Gigs. Windows only
recognizes 4 Gigs.

I have an Asus PB5 Delux MB, and DuoCore processor. And yes.. i'm 100% i
have 64 bit Vista Premium.

The BIOS settings to look for are Memory Hole and MTRR. You will probably
get the best advice on these settings in the Asus forums, and may need to
update your BIOS.
