Jumper settings for Celeron 2

[DJ]

I just installed my new Celeron 566 in a P3BF with an Asus Slocket. The bios is showing a multiplier of 4.5 and CPU speeds of 300mhz and 450mhz. Is this normal? Should the Slocket be set to Celeron or coppermine. Thanks.

Hey DJ ...

I doubt that upon bootup it is also labeled as 300 or 450 ...

All multipliers are fixed since some olden P2-350 CPUs (and some rare engineering samples for reviewers), hence I guess your BIOS settings would be overridden by the CPUs setting.

The Cel566 comes with an 8.5 multiplier and should run @ 850MHz (100MHz FSB) without too much effort.

I set my slotket to celeron, but didn't try the coppermine setting yet.

I must tell you that I have been following your thread. Just to confirm that when you overclock to 850 it shows up on bootup but as 450 in the bios. Mine currently shows 566E on bootup. Thanks for the help.

Hi DJ,

the recognition upon bootup is correct and means
566E > your CPU is running on a 66.6MHz FSB
566E > it is recognized as Coppermine core (probably your jumper could change that)

Now ensure you're running the latest BIOS version on your MoBo and I hope you loaded the setup defaults after updating it.

I'm not too sure what options your slotket offers, but I guess ASUS made a good one with either jumpers and/or switches. Thus I think there should be setting for VCore default (or auto detect) and same for FSB.

Choose those default options as your P3B-F offers more than enough in its SoftBIOS ...

Enter your BIOS menu head to powermanagement and note down your temp after 5 minutes of waiting in that screen.
Set your VCore to 1.8 volts, safe changes and reboot.
Go again to your powermanagement menu and set VCore readout to 'ignore', because most likely there is an 'ERROR' stated besides the VCore readout, and don't forget to check that it is really set to 1.8 volts ...
Now enter your FSB setup menu and go for 100/850, safe changes and reboot.

From that point on I recommend SoftFSB for finding your highest safe clockspeed and if you need help with that, just come back here and I'll give you a hand ...

I'm looking forward to read your progress and I guess 850 is the minimum you can achieve.

Cheers,

Hey Maggi,

I had it running stable @850mhz with a big fan blowing at the case. I changed it back to 566 and has since then been unable to get back the voltage to 1.8v. It does say 1.8 in the advance tab but 1.55 in the hardware monitor. Even setting the vcore monitor to ignore has no impact.Any ideas? Thanks.

Forget previous post. 566mhz @850mhz as we speak!!!!

[Maggi]

now go ahead and try the upper ranks ...

Hey Maggi

I don't think my video capture card would like that. By the way I have it stable with 1.65v vcore. Temperature hovers around the 52 degrees C. Two questions. What is a safe temperature range and which guage is more accurate, the bios or the Asus probe? Thanks
