Anyone overclock a Dell

[tomrizzo]

Anyways my girlfriend has a PII 400, I want to overclock it, maybe make it last a little longer. But in the bios, there is not a single option for changing the fsb. Anyone know of a proggy that change it, thanks. And by the way it is a Dell.

I remember there was a program called SoftFSB or SetFSB or something. You could changed the FSB in Windows. I have been trying to find it, to no avail. Does anyone know where this program or a similar one can be downloaded?

Here is a quote referring to a Dell Dimension XPS-R series system excerpted from this site's XPS-R upgrade page(scroll down to about the middle of the page for the link to the page).




<< Why can't I just overclock the original processor, or a Pentium III processor?

The only known way of doing any processor overclocking on these machines is running a Celeron processor at 100 MHz FSB as mentioned earlier. All processors made since midway through the Pentium II era (which probably includes most or all of the ones that came in these machines originally) are multiplier-locked, so the CPU will only run at the multiple of the FSB speed that it is designed and tested to run at. The only other way of overclocking a Pentium II or Pentium III would be to increase the FSB speed past 100 MHz.

However, this does not appear to be possible on this board. The clock generator chip on my system's board is a Cypress 48C101-01, its datasheets are available here. (It's a rectangular chip, mounted on the right side of the board in the area of the AGP slot, next to a small silver can which is presumably the clock crystal itself.) This data reveals that this chip's FSB setting is set based solely on the signals received from the processor slot, so it is not changeable through software, and in addition, the ONLY supported FSB speeds are 66 MHz and 100 MHz anyway. >>



EDIT: There are several CPU utilities located here.

I tossed one out of a moving truck at 75mph, it seemed to help the performance for a few seconds before it crashed.
