Dell XPS400 Dimension 9150 memory
I went through Dell's website for memory upgrades and based on Dell's and also Crucial's update advisor I purchased 4 x 1gb PC2-6400. I noticed that my memory isn't running full speed though, it says 667mhz in the BIOS. I updated the BIOS hoping that it would solve the issue but it hasn't. Why is it not running at the right speed? How can I fix this? If this pc can't handle the speed why is it on both update sites? I hope I didn't waste my money. I was running PC2-5300 and the upgrade advisor recommended this ram upgrade.

I'm running Vista Basic 32 bit by the way. Does this have anything to do with it? Do I need a 64 bit OS or something to get the full speed? I know it only picks up 3.5gb or ram instead of 4gb right now too.

Dell and Crucial both said my pc supports it and recommended the upgrade. They need to fix that, wasted my money thanks to the upgrade advisors.
