Intel Pentium 4 and Celeron socket 478 infos

[cedrik]

i need help with a simple problem:
right now i'm sorting my Sk 478 Intel cpus..
most of them worth 1-2 usd but i saw that are some that are rare...
until now i found just 2 both, Intel Pentium 2500/400 SL65R and SL6PN...
need help to find other rare sspecs (that worth > 3 usd)..

thank you

Northwoods with 400 fsb and high speed can worth more (at least on ebay).
And Willamette 2.0GHz.
And 3.4 Northwoods and Prescotts.
And i think some unusual speed grades, like Mobile Nortwood Celeron 1.2 and 1.4.

SL5?? NWs tend to be less common, likewise SL6?? Willamette's (not all, but in general)

High speed Northwoods with a 400FSB used to bring descent money (e.g. 2.8GHz 400FSB) because of people upgrading old machines, but have started to fall off.
