Have a HP Pavilion 7955 which currently has a

Pentium 4 1.5 GHz 400 FSB
Socket Type - mPGA478

HP stated that they've only tested up to 2.0GHz

WHY can't I upgrade to 3.0GHz & 800MHz FSB or higher.

Not looking to get a new Computer just looking to see if this one can be upgraded for a small price($100). Just added 512 MB of RAM for $60.

Please if any one could provide any input I would greatly appreciate it.
