It was easy plug and play and the computer operates much faster..

This CPU was used to upgrade a Dell Dimension 4700 from a 32-Bit CPU to a 64-Bit CPU. Unfortunately the motherboard only has a maximum RAM capacity of 4GB (only in 4 x 1GB configuration). I was hoping to install 8GB. However, with the x64 CPU all 4GB can be accessed. With the x32 CPU only 3GB can be accessed. The computer also boots a bit faster and launches apps faster now.

Pentium 4 640 is much faster than the Celron D 331 I was running prior to installation. Price was right as well, with Free shipping.
