I am running an aging Dell desktop (XPS Gen 4) which is based on the Intel 925XE chipset. I currently have 2 gigs of PC-4200 RAM. As I am still running Windows XP, I don't really think I need more than 2 gigs, but thought I might benefit from faster RAM.

The 925XE chipset has an 800 MHz FSB, but I don't know what speed of RAM it will support. Crucial's website says PC-6400 (800 Mhz) RAM will be "compatible" but will this RAM actually run at 800 Mhz in my system or will it be limited by the motherboard/Bios to a slower speed (and thus defeat the point of the upgrade)?

The dell supports either 533 or 800, and it should detect the faster RAM.

Of course if you mix two sticks of 533 with two sticks of 800, it will run it all at 533.

Personally I don't think you'll notice a big diff between the two. I've got one dell with 4gigs of 800mhz ram and one with two gigs of 533, and they seem pretty similar to me.

Of course the one with the super-duper video card seems 10x faster.
