ModelPerfect · 06-24-2008, 10:57 AM

So I'm building a new system with a Core2Quad Q6600 processor, 512 MB NVidia 8800GT, and 4 GB RAM (the Asrock 4Core1600P35-WiFi+ motherboard actually supports 8 GB). I did some researching and was under the impression that I needed a 64-bit OS to recognize the full amount of RAM. Not wanting to go to Vista, I opted for XP Pro X64 and upgraded to SP2.

The BIOS does indeed recognize the full amount of RAM, but the OS only sees 3.25 GB, which is what most people said would be the case under a 32 bit OS. I have already have the latest version of BIOS, but it doesn't have a memory remap option (something some articles mentioned).

Anyone have any clue what's going on, and how to get my system to recognize the full amount of RAM? If I can't get full use of the 4 GB, is there any advantage to using a X64 system, rather than my trusty old XP Pro X86 version? What's the GFY gurus take on Vista X64?

Thanks a lot in advance....
