    Turbo mode in opteron 6200 series not work

    a.green

      In the wiki page, it is stated that Opteron 6200 processors have turbo mode. For example, 6274 base frequency is 2.2GHz while it can reach 3.1GHz o half load.

      Our motherboard is tyan 8236. I also run a single program on that. However the /proc/cpuid shows one core has 2.2GHz while the other have 1.4GHz frequency.

       

      So what is the turbo then?Why it doesn't go to 3.1GHz??
