how many different versions of the p4 are there? how can I tell which version I have without opening the case and removing the heat sink... I know it comes in 3 flavors, 400mhz 533mhz and 800mhz... is there different names other than northwood
 
Northwood, willamette, Prescott.

Willamette = 400fsb 256k cache
Northwood = 400/533fsb 512k cache
Prescott - 533/800fsb , 512k cache possibily
 
Willamette = 400fsb 256k cache 423/478 pin

Northwood = 400/533/800 FSB 512k cache (HT on some) 478 pin

P4 Extreme Edition/ Galatin = 800FSB, 2MB L3 cache, 478 pin - too expensive!!

Prescott - 533/800fsb , 1Mb cache, SSE3 (HT on most) 478 pin

Tejas/Prescott 800/1066FSB, 1MB, HT high pin count (like 700)

Multiple steppings. Current best is the 800FSB, HT enable, D1 & MO Northwoods. Ex: 2.4C, 2.6C, 2.8C, etc...
 
Thanks for the info, I have the 800mhz Northwood... I am having some problems overclocking this chip, well problems compared with other oc'ers.
