    I have a i915P/i915G chipset I want to upgrade my cpu for my Dell optiplex gx 280

    walt

      my pc is a dell optiplex GX 280 small desktop. The stock cpu is an intel pentium 4 520 2.8ghz 1m 800fsb 04A. I recently purchased a pentium 4 660 3.6ghz 2m 800fsb 04B. and when I installed it it said incompatible cpu system halted!. now after much research would I be correct to think that I have to use a cpu that is  04A instead of 04B? perhaps like a pentium 541,550 or 650 these all are 04A because other than that I can think of no other reason why it would not work. I don't know much about computers and really would appreciate if someone can explain this to me!     and I have the latest bios updated
