OverClock Processor does anybody know if I can?

Question

I have a HP Media Center Edition
Mother board is a MS-6577 v2.x Xenon3
Socket 478
Pentium 4
Front Side Bus Freq is 400/533
Chipset Name is Intel 845G-B
Chipset "North Bridge" is intel 845G-BCH
Chipset "South Bridge" Intel CH4

Right now I have a Intel Pentium 4 2.66
400/533 MHz Front Side
Socket mPGA478

What I really want to know is it overclockable and how.....And if not how much can it be update.
I recently got the Motherboard specifications on the board because I was upgrading the memory and I put in a PC3200 it's not even susppose to be able to read it but, it worked if anybody has messed around with these motherboard what are the true upgrading speed? Since HP Specifications are wrong? Thanks any answers will be helpful.

But do you know if this motherboard will read more than the specifications of 400/533MHz? Far as I know the fastest HP shows by the front side bus speed on the processor 533MHZ is like a 2.8GHz biggest processor I have seen on a Desktop HP. Would this motherboard read and handle more than 400/533MHz Proc. Front Side Bus Freq? Thanks

Answer 1

no, you cannot overclock generally on prefab computers. OC requires a mobo made for OC as well as a hefty heatsink (usually)

Get a 2nd hand mobo (intel 865) (maybe about $50/$60)
Overclock the cpu past 3Ghz and get a refurbished gfx card, like a 6600gt.
