Northwood 400MHz to 533MHz fsb pin mod?

[rogue1979]

I already tried the search function and google, does anyone have a link for modifying a Northwood "A" to a 133MHz fsb from the default 100MHz?

All I know is that you have to break off one of the processor's pins. Someone around here knows how to do it, but I don't think they "get here" until the evening, usually.

OK, thanks for the info, I thought it was as simple as removing one pin but I couldn't remember or find a link.

I actually bought a Celeron 1.6 mobile (Northwood core with 256K L2) and am going to swap that out with a Inspiron 2.8GHz B from my Dell. It only has a Radeon 7500 32MB video chip good for light to medium gaming only. I am sure 2133MHz will give the same video performance as the 2.8 as long is it stays on a 533MHz fsb. From everything I have read the mobile Celerons with 256K L2 cache perform within 5% of its 512K brother. The other benefits are heat reduction and increased battery life, the 1.6 mobile runs a default 1.2v even at 2133MHz.

A short gaming excursion on the 2.8 Inspiron gets real hot and makes battery life miserable.

The 2.8 will see duty on a desktop at 3.0GHz+.

I'm not sure about any pin mod, but I was able to run my old P4 1.6A at FSB 133 by simply changing the FSB on the MB. The chip didn't seem to care what the FSB was set at and did overclock pretty nicely with just that simple setting adjustment.

The pin-mod is for people whose motherboard's don't support changing the fsb, like in a laptop.😉
