You will not believe what I have done.
I decided to BSEL mod my Celeron 4 (P4 variant Celeron) that I had on my desk for a LONG time. Pulled out the P4 2.4GHZ and plopped in the 2GHZ celeron. I knew it had a very low FSB, so I tried BSEL 0 & 1 low first. It ran slower than normal. I proceeded to use Bsel0 low Bsel1 High and got a regular 2GHZ. Then tried Bsel0 High Bsel1 Low and got 2.66GHZ. Not bad but not enough to make up for the less cache on the Celeron. I then thought, hmmm that P4 had 800MHZ FSB yet no configuration matches it... what if I try BOTH pins high (marked as reserved/disabled). I expected 3.0GHZ , but got 4GHZ!!! NOT JOKING! 100% overclock. Everything runs great but Firefox, its real buggy. I may need to bump up the vcore with a VID mod, but dont know which one.
Proof its REALLY overclocked that much here:

Current VCore is about 1.5? Not sure, will reboot and edit.
