The Dim 4400 can take up to a 2.4Ghz cpu with a 400Mhz FSB. It sounds like the cpu you installed has a 533Mhz FSB, so the motherboard will only run it at 400Mhz and that will lower the clock speed to 1.8Ghz.

I have a Dell Dimension 4400 with a P4 1.6 GHz processor. I had a spare 2.4 GHz P4 processor that I installed and it worked except that it detected the processor as 1.8GHz. &nbsp;Dell's technical specifications for this computer say that it is capable of recognizing P4 processors up to 2.4GHz, but I could not find any documentation on how to manually set clock speeds or even a diagram of the system board. Does anyone know how to get this computer to run at the full 2.4GHz that it should be?

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
