Turbo boost freq are design by intel, and enable under conditions define by intel, you can look at what they are or their state with i7z but you could keep inspecting freq scaling datas, it will never answer it.įor my i7 here's the result (as you see, i'm not handling freq_scaling at all): So when you read possible freq done by cpufreq you are reading possible values of the cpu on its energy saving ability nothing related to cpu boost. One feature is to slow down cpu to save energy base on some state (cpu throttling, running on battery.)Īnd the other feature, cpu boost, is a feature to overclock some cores when busy but not on all cores (the idea is to max out cpu usage for non multi thread program that use few cores by increasing the core in use mhz) there is nothing - absolutely nothing - half so much worthĭoing as simply messing about with Linux. I installed i7z to get current values and under load it My i7-2600 has max freq of 3400 but turbo works fine $ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq My scaling max frequency is set at 4 GHz not 4.4 GHz so the turbo boost will never be applied if I am correct? I've read the link but do not see how it applies. I am having issues getting Intel Turbo Boost to work with my i7.
