Run 'sudo apt-get install msr-tools' to install it. The following script can be used to turn off/on turbo boost:Įcho 'msr-tools is not installed. Note: you need to run the wrmsr command for each cpu core.Īfter disabling turbo boost, I am able to complete my GWT compilation altough the temperature still goes as high as 90 degrees. 0, 1, 2, 3., you can get those number by running cat /proc/cpuinfo | grep processor. To re-enable turbo boost on all your cpu cores: sudo wrmsr -pi 0x1a0 0x850089 where i is the cpu core number, e.g.Note: you need to run the wrmsr command for each cpu core. To disable turbo boost on all your cpu cores: sudo wrmsr -pi 0x1a0 0x4000850089 where i is the cpu core number, e.g.First, you need to install msr-tools: sudo apt-get install msr-tools The Intel Turbo Boost Technology allows processor cores to run faster than the base operating frequency as long as they are operating below the limits set for.So I looked for resolution and found disabling turbo boost can help. The cpu temperature increases to 100 degrees in about 3 minutes even if I set the fan speed to maximum 5000rpm. The computer turns off when compiling GWT code because of cpu overheating. Normally it should display the Turbo Boost clock rate of 3.2 GHz as the max frequency, but it won't do it.I have a Thinkpad T410 laptop with i5 cpu. It seems that Turbo Boost is enabled (of course, it is enabled in the BIOS), but it won't overclock even though underclocking is working to save energy. The governor 'ondemand' may decide which speed to use This is the output of the 'cpupower' command: ~ $ cpupower frequency-infoĬPUs which run at the same hardware frequency: 0ĬPUs which need to have their frequency coordinated by software: 0Īvailable cpufreq governors: conservative, ondemand, userspace, powersave, performanceĬurrent policy: frequency should be within 1.20 GHz and 2.40 GHz.

To test if the OS is the problem (I have tested Linux Mint and Debian), I've put the SSD in my computer with an i7 3770 where the Turbo Boost works perfectly fine. The problem is that the processor isn't overclocking, and uses 2.4 GHz as a max frequency. I'm using an Intel Xeon E5 2630 v3 which should support Turbo Boost up to 3.2Ghz, according to Intel's product page. I'm trying to enable Turbo Boost on my server.
