    sSpec stepping code mismatch

    cmccord-q9

      What are the implications of running a dual socket chassis with mismatched sspec or stepping code. I know virtualization documentation asks that the CPU's match but are say windows or linux effected by a mismatch.

       

      Does the microcode driver update each cpu with the matching microcode? Does a system call that would relate to a microcode update only get processed on the updated cpu? Will it cause system unstability?

       

      If someone can point me to documents explaining this it would be appreciated.
