I also mention that, monitoring with i7z the clock of my CPU, when intel turbo
is not working I get different freqs for each core
Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 %
Temp VCore
Core 1 [0]: 1126.19 (11.23x) 7.99 93.9 1 1
40 0.6274
Core 2 [1]: 1239.87 (12.36x) 3.2 95.1 1 2.11
41 0.6208
Core 3 [2]: 1577.66 (15.73x) 3.7 95.4 1 1
38 0.6257
Core 4 [3]: 1316.89 (13.13x) 7.23 81.9 1 12.8
39 0.6257
Core 5 [4]: 1572.58 (15.68x) 10.2 87 1 4.73
39 0.6257
Core 6 [5]: 1916.98 (19.11x) 8.02 90.6 1 1.44
39 0.6266
However, as soon as I load 1 core to 100%, all goes at the maximum frequency
(here I'm limiting the maximum and also the core is under-volted to keep the
temperature stable.
