Specs: Windows XP, Pentium3 550mhz/128mb
I have a HP vectra Vei8 computer that i have a 1.0GHZ processor to replace the P3 550, the fsb on the old processor is 100 mhz compared to 133 of the new precossor and i do not know the jumper postions of the motherboard. Thanks

"the old processor is 100 mhz compared to 133 of the new precossor and i do not know the jumper postions"

Are you sure a 133MHz FSB CPU is even supported? I highly doubt that it is, but you *may* be able to get it to run at 750MHz (7.5 x 100MHz)


Do you have PC100 or PC133 RAM? With a 133MHz FSB CPU you *should* be running PC133 or you'll take a performance hit.

"Pentium3 550mhz/128mb"

Are you only running 128MB RAM? That's pathetic. You need a RAM upgrade more than a CPU upgrade. XP needs at least 512MB to run reasonably well, more would be even better. You should be running Win98 on a system with those specs.

I've got an old Vectra VE P-III that's probably about the same as your VEI. Can't remember where I got it, but it had XP running OK on it so I just updated the hardware as much as I could.

I just ran Everest to see what I put in it. It's got a 1.1 gig coppermine CPU in it at 11 x 100 and I think that's the fastest cpu I could get to work in it. I remember that particular cpu had a 100 mhz FSB. I'm pretty sure I tried some 133 FSB cpus and the only reason I wouldn't have used one is the mobo couldn't do 133. And as I recall, the 810 chipset is locked at 100 mhz. Everest also reported it's an Asus Hawk motherboard.

Some of the old P-III motherboards couldn't handle the new architecture and/or core voltages of the faster P-IIIs. Often a bios upgrade would add that support. So check the PC manual and HP's support page for that model.

And you should probably try to find a cpu with a 100 mhz FSB. They're cheap enough on ebay.

Computer has 512 Megs of ram now must of forgotten to upgrade post. The processor was free so ill keep trying. The problem it has is when i boot up the processor speed reads at 750mhz (7.5 *100) which is fine becasue the processor was free. the computer it self boots fine will get into windows but after 5 to 10 minutes the comp will lock up. That is the main problem so i though there was an agrement error.
