newby needs help in overclocking celeron 400 in a hp

[billp]

I have a hp pavilion with an asus mew-vm mobo and a 400 mhz celeron .There seems to be only one jumper for fsb 66 or 100 mhz. It will post at 600 mhz with the fsb set to 100, but that's it, it won't load windows
just freezes at the windows logo. I saw something somewhere about jumping pins on celerons, (on the cpu itself) is this possible. Is there anything Ican do outside of replacing the mobo ?

Thanks for any advice

Since you make it to the logo and it posts and all, you may have a heat problem.

Most of those old school Celerons won't even post at 100MHz and you risk burning that thing out.

It would take a great deal of cooling, in my opinion, to run that chip somewhat safely at 100MHz.

I don't recommend trying that again until you get something that can keep it cooled extremely well.

I think I need to crank up voltage , but how . The heat sink is barely warm to touch , doesn't seem to get hot.

Thanks for your reply

Unless you have jumpers on the board or someway through your BIOS (which I doubt) you really can't. There is a trick to rewire the VID pins if it's a PPGA processor, but I don't know if that works with the Mendocino cored Celerons or not.

You may be lucky and have one that is like the old 300a that could hit 450 almost every time but I'm really not sure. Only thing I can recommend is nore cooling unless someone else steps in that knows something I don't.

100MHz is ALOT for that chip to handle whether the heatsink feels warm to you or not.

It is a ppga, oem sl3a2, mbo, vcc core 2.00 volt . How can i jump the pins ?

Thanks for any help
