Thanks for an interesting post. I’ll have to look into it some more because I’m faced with this same issue right now.
I have a ASUS A8N32-SLI Delux mobo with 4 gigs or RAM. (4 * 1GB - Dual sided). When I go into the bios, it tells me that there is 4GB installed but only 3.38 Avail for use. Now I’m not sure if this is a bios issue or a mobo issue but if anyone has any clue, I’d love to hear it. (I’m planning an upgrade to my bios sometime this weekend - maybe that might work?).
I also have Vista 64 bit installed with VPC 2007 (The reason for my 4gb is so I can run an XP image with ease).
