Swapping CPU's

Intel / PENTIUM 4

Specs: Windows XP Pro
I'm thinking of swapping a Celeron 2.3 GHz CPU for a Pentium 4 2.4 Ghz from a redundant machine. Both computers are Dell dimensions and the recipient M/Board is compatible with the Pentium 4. My question is - Is there any real benefit to be gained in doing this?

Yes, there will be a benefit. The Celeron was a cheaper version of the Pentium and being the same speed should improve performance a little, mainly due to the larger internal cache. Exactly how much depends on the type of work you do but don't expect any miracles.


Be aware that you wont just be able to boot from the existing Windows XP installation as soon as you replace the CPU. A best you will have to do a repair initial so the OS can pick up the correct drivers for the new CPU.

Thanks Stuart.........What's a repair initial? will this launch
automatically when I boot up after swapping the CPU?

Thanks for your help

Sorry. Typing error. I meant a repair install. Dumb spell checkers!

Yo need to boot from the Windows XP CD and go through in installation process but one the installation has recognised the existing installation select R for repair instead a new installation.

This will go through the installation process but keep all your files and setting intact.

You don't need to do a repair install. You're going from a Pentium 4-based Celeron to a true Pentium 4; the only difference between the two is cache size. Just pop it in and go.

Processors don't require drivers.
