    What is the fastest chip I can use to upgrade my pcchips based MOBO?

    I have a Professional MainBoard mobo that appears to be using pcchips as a base. The manual states:
    "Supports either p54c/p55c Pentium(MMX) CPUs with 321 zif socket and Cyrix/ibm 6x86l/6x86MX (M2), AMD K6, IDT C6 Processors with External Clock Speed at 50/55/60/66/75/83 MHz."

    The CPU core voltage can be 2.2v/2.8v/2.9v/3.2v/3.3v/3.5v

    It's a socket 7 mobo with clock multipliers from 2x up to 5.5x.

    I'd like to move it from the 200Mhz pentium MMX up to 450-500Mhz. Any chip recommendations?

    Then ya should get the AMD-K6-2 500Mhz.

    You are sure the fsb can go to 83Mhz, right??

    Well, the k6-2 line of cpu's have their 2x multiplier re mapped to 6x, so if ya set it to 2x on yer motherboard, the cpu will see it as a 6x multiplier.

    And we all know, 6 x 83 = 498Mhz, which I asume is acceptable??

    They can be found for dirt cheap, so....

    Thanks a bunch. I've tried the salesperson route and they all just look at the specs and say sorry it says 100 MHz bus. It won't be compatible. Though I saw Tom's hardware site where he said nudge your bus to 100 indicating 83Mhz will work. , but needed confirmation.
