In addition to CLOS enable status, also show the core-power feature status. This will help why clos enable status didn't give desired results as the core-power feature may be disabled or unsupported. The new display looks as follows: $intel-speed-select core-power info Intel(R) Speed Select Technology .. package-0 die-0 cpu-0 core-power support-status:supported enable-status:enabled clos-enable-status:1 priority-type:0 In the above display "support-status" and "enable-status", shows the status of the core-power feature and "clos-enable-status", shows the status of the clos.
