I am just wondering if anyone knows where I can information about compatible processor upgrade for my Dell Dimension 2400 computer? It currently has an Intel Celeron 2.7 GHz SL77S.
Any Pentium 4, Celeron or Celeron D with a 400MHz or 533MHz FSB (front side bus) and using the Socket 478 interface should work. Off-hand, I don't know specifically the limit, but you're looking at older chips, which you can probably find used on the cheap.
