There is a reply to a post on Tomshardware about checking SpeedStep in the BIOS to make sure it's enabled. I have not though of that feature in a long time, but that can limit the CPU speeds.
Yes, it's a must that SpeedStep be turned on in the BIOS for proper operation, this is what makes the CPU 'shift gears', so to speak. Make sure you have the latest BIOS for your computer installed. Dell tends to be one of the better ones to have BIOS & driver updates available. Just don't mess with the automated software offered, manual checks are best.

Visit the Dell Drivers page (2nd link below) & enter your Express Service Code, which should be somewhere on the computer. Maybe behind battery on notebook. Can also be obtained via Belarc Advisor, will be near top of report.
