Compaq deskpro 4000

[rico]

I am building up an old deskpro 4000 p2 slot 1 233 32mb ram + not many decent upgrade slots what i need to know is a P3 550mhz going to slot on to this board and make any difference? my friend has this processor and will give me it for a song

Check on your processor at intel's site; i would say you have a 66mhz front side bus on that chip-so you'll not be able to use a p3 whcih normally run at 100/133mhz. You can go up but you don't want to go down-procesor's aren't backwards capatible like memory sticks; at least i 've never heard of it happening and i wouldn't want to experiment! http://www.PCGuide.com/ubb/wink.gif
Check your motherboard/processor specifications-you may be able to overclock the board to accept 100mhz, but i doubt it on that old Compaq, sorry. http://www.PCGuide.com/ubb/frown.gif

rico: Get a motherboard manual, if possible. It will tell you the CPU's supported by the board/chipset. If it still runs or boots at all, you can get the BIOS ID String, you only need to boot to the first screen, so no floppy, hard drive etc are needed, just CPU, memory, video card and keyboard. Press [Pause] to stop the first screen while the memory counts up, and write down the BIOS ID string, the long number usually in the lower left corner. Note the BIOS brand also. Then go to Wim's BIOS (http://www.ping.be/bios/) and look up the board, possibly find a manual and maybe even a BIOS upgrade.

iisbob: Please do not suggest overclocking on this forum, we're here to help these people FIX computers, not fry them or make them unstable. Overclocking by increasing the system bus speed will speed up everything, and can easily damage video cards, memory etc. Strongly not recommended...

If the person specifically asks about overclocking, it's no problem to answer, I prefer with a warning and some links explaining the risks, but I strongly prefer NOT to suggest that someone try it if overclocking is not included as a possible option in the original post.

Overclocking, the Dissenting Opinion (http://www.pcguide.com/opt/oc/index.htm) from the PC Guide (http://www.pcguide.com) is a very good article explaining the risks of trying to run your computer at speeds higher than it's originally intended to run.

Whoops, sorry pete-you kinda get used to things with other geeks; u know?! I certainly do not recommend someone get into OC if they're not famailar with it. Actually, i see very little use for it on modern systems anyways( thats a very controversial topic in my friends circle). Have to remember that most people that post on this site don't know the diff between memory and hard drive storage! http://www.PCGuide.com/ubb/rolleyes.gif

To determine what you can do with that model, go here and find out what it has on it [the mobo that is]: http://www3.compaq.com/support/parts/
I'm sure you can get the motherboard specs somewhere at the Compaq site. You need a mobo with a 5.5 multiplier on 100 mhz bus, I think, to do the PIII...I'm nearly sure the motherboard you have wont go to 8+ multiplier for a 66 bus even if the PIII would stand it.
