p3 550e @728mhz

[bosshogg]

ok i changed the jumper on my mobo to 133fsb so now im running my p///550e@733

before when it was 550 i had idle temp at 33*c and now at 733mhz fsb133 i have an idle temp of 29*c!!! how does it get colder?!?

can it get too cold?
i need help quick because the temp just dropped to 28*c!

oh and i opened my case and i now have a house fan aimed at an angle at the cpu.

Hi bosshogg, wellcome to the Forum,
Really a nice Overclock at acceptable temps, probably with a better cooler you can go with a 133Mhz of Fsb, better for your Pci cards & Hd's that now works @40Mhz (1/3 of the Fsb) but if you wanna upgrade your system, well a P/// 800E works great @1066Mhz with 133Mhz of Fsb and can go easly up.

I hope it helps you, and still many comps ;)

thanks for you reply.

today i tried booting it up @ 132fsb again and win2k said that it was missing a file and i had to use the startup disk and reinstall..

so i changed it to a lower fsb and it's ok now.

now to change it to 133fsb, in my mobo manual there is a jumper setting that i can change, right now it's at 100-132 setting.

so i need a better cooling system if i want to change it to 133?

was that windows problem because the chip was too hot?

The Pci freq. is linked to the Fsb freq. and works with divider factor of 1/2, 1/3, and 1/4, so going with a Fsb of 133Mhz the Pci clock works with the standard value of 33Mhz (1/4 of Fsb), with a Fsb of 132 the Pci freq. is around 44Mhz (1/3 of Fsb), too higher for many Hd's with possible Fat corruption and Pci cards instability.
At this point my suggestion is to go with 133Mhz setting the proper jumper on Mobo, but check constantly your temps, better stay under 50 degree C to gain safe & rock stable OC.

bump, it's updated, need help

Don't worry,
lower temps are better for every kind of chip, you must only check, if you've an external thermal sensor, that is right seated, better beteween the Chip core & the Cooler, but without the metal clip.
Sorry for the leater reply :) and many compliments for your OC.
