Processor And Motherboard FSB Frequencies Must Match?
Posted on 2003-03-01
I have a P4 2A GHz processor (2.0 GHz). The bus speed on the processor is 400 MHz. I also have a motherboard, but the bus speed on the motherboard is 533 MHz. Well, I put the processor into the motherboard and it worked. Frequently when I turn the computer on, though, I get an error message at the BIOS saying "no CPU installed". Is this due to the mismatch in the bus frequencies? Would I need a motherboard with 400 MHz FSB? Could this mismatch possibly have damaged anything? Also, when I go into the BIOS settings, it says the CPU hung due to an incorrect frequency multiple, or something of the sort. So basically my question is, do the CPU and motherboard FSB frequencies have to match? Thanks!
