Need help! Trying to enable 133Mhz FSB on a HP Pavilion 7920

[RaiderJ]

Swapped out the 900Mhz Celeron (100Mhz FSB) that came with the machine originally for a 1Ghz PIII (133Mhz FSB). However, since the board is only running at the regular FSB speed, the PIII is showing as a 750.

The only thing I've been able to find so far is this website that talks about the board being of ASUS make, and updating the BIOS. The email on that website didn't work, and the latest BIOS on the HP website doesn't fix it either.

If you can find out how to fix this, BIOS update or jumper setting, I'll mail you your choice of DVD from this list of DVD's I have for sale.

Thanks!

Dumb question, is the ram the original PC100 or PC133?

I'm assuming the original RAM is PC100, but the memory has since been upgraded to 256MB PC133 sticks. I don't think memory should be an issue if the FSB is set to run at 133Mhz.

could you take a picture of the mobo around the cpu socket? or are there no labeled jumpers there?
edit: run CPU-Z and post what mobo it says you have. it may be possible to download the non-hp BIOS for it.

No jumpers that I can find... the website I linked to in the first post mentioned something about soldering on jumpers himself... maybe there are contacts on the board that can be soldered to?

I also tried to figure out if the board is of ASUS make, what ASUS model it is, but I didn't have any luck.

Can you load Everest or some kind of similar program that will give you info on what motherboard chipset the HP is using? You need to find out if your HP has an Intel 810 or 810E chipset. If your computer just has a plain-jane 810 and not the enhanced "E" version, you might be limited to only 66MHz and 100MHz FSB settings.

Since it keeps defaulting to 750MHz, and the machine originally came with a Celeron, HP may have cheaped out and put in the basic 810. If that's true, you could very well be SOL without a motherboard upgrade, since I don't think there is any way to mod or BIOS flash an 810 to an 810E in order to give you the 133MHz FSB.

I'll have to give that a shot. Not sure what chipset it is.
