Have old Compaq Presario Model 5030. The board is a Compaq O4C4H, Bus clock 66Mh, with a 300meg Pentium II, Ram @ 128Mh, I would like to install a faster processor in this. I think it will take a Pentium III with more speed, but am not sure. would appreciate your input on this. Thanks

A P2 board will NOT take a P3 and vice versa. Sorry, but in short, thats the answer. Good Luck and Happy Computing, Kailas Shastry, India.

You can run a Celeron 400mhz - Slot 1 JP # 1 2 3 4 ___ On Off Off On You can get to Celeron 533mhz with a 370 /Slot One (Slocket) adapter and all jumpers off. or get to 1000mhz with a powerleap adapter from www.powerleap.com Kap'

@Kailas, not entirely true. There appears to be some PIII procs that conformed to slot 1 specifications, but then there is the issue if the Compaq motherboard would support the settings to accomodate the CPU to the fullest. That would be a question for Compaq to answer. http://users.erols.com/chare/sockets.htm And then there's the issue of the availability of said processors.

The best speed I found was a 766mhz that apparently is plug n play from: http://www.upgradestore.co.uk/acatalog/Processor_Upgrade.html I tried for ages investigating this issue as I to have a PII 300 in my PC, anything faster than this was a no go because of the 66mhz FSB speed. I am still contemplating whether or not it's worth the money as a second hand PIII 1.5 - 2 gig complete machine can be obtained for a couple of hundred quid. M M

funickk , thanks for correcting me there. Doing some google work now :) btw wrt reference to response#4, I found this on the link given - PC100 FSB Now this requires a 100Mhz FSB to run at its full potential. I dont know if the mobo in question can provide the required speed. Good Luck and Happy Computing, Kailas Shastry, India.

Thanks to all. From your input and that of others, I'll begin a search for a p3 that will fit a slot one board and step up the FSB to 100Mhz once I have it in. It will either fly or fry. gonna be fun to give it a go. Thanks to many!
