P2 450

[Dr. Strangelove]

I've got a P2 450 with an Asus P2B. My board manual specs it for 233-400MHz. I'm running 128 meg of ram. From what I've read sofar this may not be a good candidate for overclocking but its all I've got to work with so here goes. Any recomendations? I may wind up upgrading the board and processor to an AMD if all else fails. Any thoughts would be appreciated. Thanks

To overclock it, try increasing the FSB (You can do this from your BIOS). A little at a time, see if it can still boot windows + be stable in games and applications.

Cooling is the key to a succesful overclock, so you should consider getting some better cooling.

If I remember well, you must set the Jumpers on Mobo to obtain the desidered Fsb, but be carfully, check your system temps (I suggest MotherBoardMonitor that you found at http://mbm.livewiredev.com/) and remember never your chip must go over 40-45 degree C.

I hope it helps you :-)

Presently I'm set with a CPU core Bus Frequency multiplyer of 4.5x @ 100MHz. CPU external clock frequency. All settings are jumpered on the board. I've downloaded an Overclocker Calc. and bumping the multiplyer to 5 should yeild 500 but I have no idea on the temps to expect. Seems I've read others have maxed out at 533 before encountering problems but I think that was on a PII-400. don't know if the ceiling is the same or not. What about voltage output selection when oc,ing a PII. Bear with me here as I'm in the deep end with little more than water wings.

The Doors, thanks for the lead on MB5.09 for monitoring temps.

Unless you are one of the lucky few, your multiplier is locked and cannot be adjusted. Your only hope to overclocking it lies in increasing the Front-Side Bus speed. Make sure your cooling is good, and before you mess with the jumper settings, read the manual pages regarding how to set the FSB speed, and also how to adjust the Vcore voltage too. You will likely have to play with both of these settings for a successful overclock.

Should I bump the multiplyer as well as the FSB or just the FSB? Board is presently set 4.5x @100MHz with jumpers for 103MHz-112MHz-133MHZ. ASUS manual says voltage output selector is not needed on the P2, it sends a VID signal direcrly to the onboard power controller. Bumping just the multiplyer to 5x = only 465MHz w/temp at 89f.

you probably can't change the multiplier on that chip. Most Intel chips are locked although some of the early P2s and celerons weren't I believe. So FSB it is, try to go a little at a time instead of all the way to 133.

[Dr. Strangelove]

How stable is the chip set in the P2B? 112MHz yeilds 504MHz @ 28c for the temp. I've got a decent heat sink and fan. Think I'll go for 133MHz.


133FSB the monitor stays blank on boot. kicked multiplyer to 5.5 but nothing. Is 504MHz all there is? Bummer. Any suggestions?

[The Doors]

Well, the multiplier of your chip seems to be locked like results by your endeavours, so you can OC it rising the Fsb from the original 100Mhz to the desidered freq., or better stable :-)
Are you sure that 28 C is the real temp of the chip? or you have an external temp sensor on the HSF or between the chip & HSF?
