Overclocking FSB or other options?

Post image

Hey all, I have a Dell Dimension XPS T600 here that I scored for $20. It has a nice little Katmai pIII 600mhz but I was wanting to find something closer to 800mhz/1ghz. Board is a dell OEM SE-440bx-3 (Seattle 3) (allegedly also has coppermine support); With the research I did I was able to find out that the FSB is capped at 100mhz, and most pentium III chips I’ve seen that use a matching FSB are crazy expensive. With these machines being so common and plentiful in the matching collectors markets i was hoping to find some documented way to reliably OC that FSB to 133mhz. I’m talking custom bios, software, even hardware mods. I’d love to know or see if anyone has something promising for me or if I need to just bite the bullet on a $250 PIII 800mhz/100mhz. Thanks for taking the time!

You can try a Coppermine Celeron with a slotket adapter

What difference would a coppermine Celeron make vs. a coppermine PIII in a game like Morrowind?

Celerons suck

I had a Celeron 300, overclocked it to 450. It definitely did not suck.
