Backround:

I have a P4 1.6A Northwood, which has been known to overclock past 3ghz(with liquid cooling).  In BIOS, out of the box, it could be set for 1.7ghz, or 2.1ghz. (100 fsb or 133). 

The Saga

I decided to take it farther.  After doing my research, I gave it a go.  I upped the fsb to 138.  Wee it boots at 2.2ghz!  Then I went to 145, and upped the voltage to 1.55.  It booted again.  Having read it could easily attain 2.4ghz, I set it for 153/1.65.   It booted to windows and then crashed. 

Now I got really scared.  I quickly set everything back to 2.1.  I thought about it for awhile, and then cautiously went to 143/1.5.

It booted and everything works as normal, running only a wee-bit warmer(44C) at 2.3ghz! 8) 

Just got back from playing FS.  WOW!  I can hardly beleive the difference.  It is like a new computer.

Keep in mind the is just with the basic fan and heatsink.   

The Northwood has become a legend in the overclocking community, due to its amazing ability to overclock 50%. 

I am not sure what success people have had on here, but this is really nice!  I am planning on going to 2.4 next week, when my brother is home to supervise!

Just my tale...
