celeron overclocking

This will probably be a blast from the past for most of you.
I am surpised that my 400(66) celeron is refusing to take any more than 66MHz.
If I set it to 75 it goes all the way to the windows splash screen and just hangs as it is about to display the desktop.

I'm wondering if it is having problems with a piece of hardware since it seems to go into windows ok in safe mode at this speed.
Could it be the voodoo2 card in the AGP or the sound card or something like that?

(It's an ABIT BX MBoard).

Hope someone can help me understand this

There is also a good possibility that the AGP/PCI slots will not run at the higher bus speed. That is the problem when upping the FSB to overclock...it stresses the system bus also.

What kind of memory do you have? If you only have PC66 RAM, then it won't be able to run at 75. Try some PC100 and see what that does for you.

Finally, make sure heat isn't a problem. Make sure you have good system airflow before any attempts at overclocking.

By the way, my two systems are a Celeron 466 and K6-2+ 550, so I'm as much in the past as you!
