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??
