What CPUs can I use with this old Intel 443BX board?

[DAPUNISHER]

I did an upgrade for my nephew and now I have this old Packard Hell (bought in '98) PII 350 in a 443BX board and I was wondering since I see old Intel CPUs for dirt cheap in the FS/T forum what the fastest CPU I could drop in here is? There aren't any jumpers for multis or FSB speeds and the board uses PC100. TIA for any help

Some OEM 440BX boards would only do up to 450Mhz. BUT with a Slocket you might get it to run a 800Mhz Celeron (100Mhz Bus)

Most 440BX boards can use a Slocket and a CuMine PIII or Celeron up to 1.1 GHz. Many can also use an Upgradeware Slot-T or Powerleap Slocket and use a Tualatin Celeron 1.4 GHz, the latter being much faster. I've done the 1.4 Tually upgrade a few times now, but not on a Packeard Hell. HERE is a list of know mobos that will work with the Slot-T. If yours is not listed, it means it has not been tested, but may still work. A Slot-T is $20. C1.4 = $60, C1.3 = $43.

Thanx oldfart I knew you would have the info I wanted! I found it's a PB870 motherboard that is limited to PII500 the way it ships and flashed it to the Intel Seattle P12 05/99 bios which got rid of the annoying Packard Hell bios logo and replaced it with a motherboard manufactured by Intel Corp logo, much more and added support for the PIII450. Now my next question is since it took an Intel bios and it's all intel chipset other than the SMSC super I/O and Crystal audio will the slot-T be the best bet?

Don't know if it would work. You can try it I guess. The Upgradeware site says the SE440BX works.

I've flashed OEM Gateway and Dell BIOS's to Intel using the bios recovery jumper method. Talk about scary! Black screen for several minutes until the speaker beeps and is done. Sweated bullets the first time I did it.

LOL! Fortunately the UK PB site gave explicit instructions to extract to floppy, remove the jumper, start up, wait for the different pitched beeps as instructed then wait the extra 15-20seconds and pop the disk, replaced the jumper and F2 to tweak the bios. I'll keep on the lookout for the stuff you listed and give it a go since the price will be rock bottom anyways, thanx again.
