s2567: which cpu can I choose?

Discussion in 'Tyan' started by Mario Giammarco, Dec 25, 2003.

  1. Hello,
    I have just bought from ebay a tyan s2567.

    I put on it two cpu pentium III coppermine 800 mhz 256k cache and 133mhz
    bus with sequential number.

    I can boot only if there is one cpu. On tyan site I found a note that
    pentium must have 512k cache if I want to use two of them in a dual cpu

    It seems very strange to me: the dual pentium I use worked in a dual cpu
    motherboard, and 512k pentium III are very rare.

    Is there a solution?

    Thanks in advance!

    Does this refer to their serial numbers?
    This applies only to the newer cores based on Tualatin. If your CPUs
    have 800MHz cores, it is pretty likely, they are Coppermines. AFAIK all
    Coppermines are dual capable. There exist some developer documents
    directly from intel, where you can check stepping/smp capability.

    http://developer.intel.com (good luck, I hate their site search)
    And expensive...
    Try two different CPUs with same stepping code - if these don't work
    too, your board is broken.
