Overclocking the 333 to 500???

stopped working when i changed harddisks.... So I had to get a 333.. I have run it at 333 not problem (obviously) at 375 (5.0 x 75) seems good.. and stable.. at 416 (5.0 x 83) I get crashes in GPL.. the display just freezes.. this probably cos of the FSB at 83 maxing out teh Voodoo 2 card and causing it go freeze.... This SoMETIMES happens at 375.. but rarely... I was 500 (5.0 x 100) so I can have the FSB (sorry.. is it called something else???? the spped the cards run at) at 33mmh.. not 37 or 41.5 for 375 and 416 respectively... I know they are surposed to be hard to get there.. but does anyone know of any hints or tips.. i've tried up to 2.3 volts... and still no good It jsut gets to the win'98 start upa nd crashes.. but atleast it POST's...and seems to work ok there. but won't go any further.. :-( Are there any BIOS setting to try?? Can I try anything else?? I have tried a room fan without the case.. and it still doesn't like it... I think it isn't a heat problem cos it does start up .. and crashes soon after... hmmmmmm.... annoying.. Any help would be good.. (PLUS any oclocker guides for the 333 to 500??? not just tomshardware etc... thanx :-) James Pickard, Melbourne, AUSTRALIA PLZ email AND reply.. thanx again :-)

First, sand the CPU surface as flat as possible until you begin to see the copper coating. That is depending how concave the surface is. Second, apply a thin layer of thermal compound onto the CPU surface and the heat sink contact area. You may want to use a bigger heat sink for your celeron if you still using the standard type.

Probably because copper oxidizes. bob >Same here.

James, 1) why did you cross post to auto.simulators ????? 2) Why did you buy a 333, when you had a 300a at 450 ? 3) Do you realise that only 10-15% of Celerons can do 500MHz... your 333 may be one of the 85-90% that cannot do 500MHz ! Do this... 1) Disable L2 cache in BIOS 2) Open the case and blow a big desk fan towards the CPU at about 45 degree angle. 3) See if it is stable at 2.2V or 2.3V. 4) Increase the voltage again - if you need details of how to do this with an Abit board then email me. You may need 2.4V or even 2.5V to get 500MHz. Once you tets those things, then come back to us and tell us what happened... we can take it from there ! Most people (incl me) will *not* email you - surely you can take the time to come back and read the reply, can't you ?

Mine went ALL copper before it was flat. I didn't break anything. Jeff http://geocities.com/Heartland/Flats/1045/Celeron.html

Same here. Wonders why Intel did not just leave the copper coating on? :-)

Thanks. But sure is better in conducting heat to the heat sink. :-)

Ummm, The heatsink is Aluminum. care to tell me how you see this copper sanding will help ? The benefits stop as soon as the heat hits the alum. If the heatsink was copper .... diff. story..... Copper conducts heat about twice as well as alum. -- ---- remove the vvv from email to unspam.
