How to indentify P4 chip (speed) Help :)

[Catiaudo]

I have a Pentium 4 chip that I took out of a Gateway computer and I'm not sure what speed or anything about it. The only numbers I see on it are "A22336 01 NB4" in the corner. Can this tell me anything or more importantly tell you guys anything? Thanks


edit: Nevermind... I'm dumb and just scraped the old thermal grease off of it and I'm good to go
