I have a relatively old XPS 600 with 2gb of RAM and I want to upgrade. My OS is only 32-bit, but I've read that if I use 4gb of RAM, it will at least recognize around 3 to 3.5 GB of that. In case it matters, my GPU has 256mb RAM. Does the computer count that in the total RAM, and therefore subtract it from 4gb?

Is this true?

I'm a little confused about all the RAM options available. I want a kit of four 1GB 240-pin DIMMs, preferably Corsair, and it has to be DDR2. I'm pretty sure my mobo can support only 667mhz max. Beyond that I'm not sure. Does it matter if it's PC2-4300, PC2-5300, PC2-6400, or whatever? I don't even know what PC2 means, but I don't think my mobo could support PC3.

My motherboard is an Nvidia nForce4 SLIx16. Can that support anything like 800mhz or 1066mhz DDR2? I don't think it can, but I want to make sure that I'm not selling my self short by buying only 667mhz. I don't know if it's relevant, but my CPU is an Intel Pentium D 820 2.80GHz (Smithfield Socket 775 LGA) with an 800MHz FSB.

Thank you for any help,
Krattle
