First thing I have to ask is do you have VISTA?

only if you use Vista and have maxed out the ram on the motherboard and are using a 64bit version. it helps speed up the boot process.

Ready Boost is, IMO, a poor substitute for adding more RAM to your system. The few times that I've used it, I only noticed an improvement if my Vista machine had 512 mB of RAM (running Vista Ultimate Beta with Aero turned off and a few performance tweaks). With 1gB of RAM I didn't see any improvement, so I stopped using it at that point (running Vista Ultimate RC2 with Aero turned off and a few performance tweaks). Both were on a Toshiba M45 laptop.
