celeron overclocking

well a couple weeks ago I reported that I had oc'ed my celeron to 416mhz by setting the jumper pin on motherboard and setting bios to 83 mhz fsb.

Well it runs stable but a friend( thanks Nino!) has informed me that they were meant to run at either 66 or 100 mhz fsb , that any other rate could result in data corruption.
unfortunately this bios offers no 100 mhz only 66,75,83.

Then my friend remembered a trick he had heard about where you can cover pin B21 on a slot 1 and force it to 100mhz FSB.
http://www.tomshardware.com/1998/12/15/overclocking_special/page6.html

so I pulled the cpu , covered the pin, reassembled, and sure enough it started up at 500 mhz.
(multiplier is locked on 5 on these)
went into bios and watched temps for a while and they seemed to be ok. But getting out of bios and into an OS was not possible it was too unstable.

Part two of the article described how you could cover 3 additional pins b119, a119, and a121.
this gives you a 10% increase in the vcore so I was able to raise the voltage from 2.0 to 2.22

this extra voltage seems to have stablized it and am able to function in linux now at 500 mhz on a 333 celeron. Although it is running up around 47-48 C may want to add some cooling?

Have always been afraid to oc much but with this old celery guess I don't care...any way its been fun.🙂

is there a huge performance difference??? im about to get a 600mhz celeron into my hands and i want to oc it

haven't got that far yet thinking about putting a better heat sink on it...and maybe some new thermal paste. but yes it does seem faster.

Yeah I'm going to have to check to see if it's a date bug in fusetalk.

Aw comon it was a fun project to share.
I got Hardware coming out of every ear, just like everyone else here.
thats not what it was about. It was about taking a throw away machine and pushing it to its max.
sure the material was outdated, but that doesn't mean everyones come across it.🙁

you beat me to it!

yeah, good ole celery 300a @504, I still remember that!
 
ah this is going back to old school oc'in days. I had a 300a@450 slot 1, 366@550 ppga, 600@933 ppga. The celeron slot 1's after 333 i think started sucking.
