When I try to change it to 0 and save it it says: "Could not save the file “/sys/devices/system/cpu/intel_pstate/no_turbo”." and "You do not have the permissions necessary to save the file. Thermal Velocity Boost is a similar and simpler. Thermal Velocity Boost was first introduced in Intel Coffee Lake H mobile processors and is now carried over to Intel’s 10th gen desktop line, albeit as an exclusive feature of the 10th-gen Core i9 series. Trying to find manually the file: sudo gedit /sys/devices/system/cpu/intel_pstate/no_turbo Depending on the processor, Turbo Boost Max 3.0 is faster than Thermal Velocity Boost. Trying a suggestion in a comment under the answer ( sudo echo "0" | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo) I get the same thing. Click CPU Cache in the FIVR Control area in the top middle of the window. It’s recommend to decrease this to -100mV to start. Decrease the Offset Voltage slider, which is the undervolting part. Tick the Unlock Adjustable Voltage box in the new window. Tee: /sys/devices/system/cpu/intel_pstate/no_turbo: Operation not permitted Click the FIVR button near the bottom right in Throttlestop. The quad-core Core i7-6700K does support Hyper-Threading, runs at 4GHz and Turbo Boosts to 4.2GHz. Despite the 2.0/2.1 GHz base on most of the Platinum series, all the CPUs will turbo up to 3.7-3.8 GHz on low core loading except for the lower power Platinum 8153. This means that, instead of being able to use a CPU such as the old Core i7-6850K to provide the full.
To disable it, I get "Operation not permitted": echo "0" | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo It has a base frequency of 3.5GHz and will Turbo Boost to maximum of 3.9GHz (on a single core). However, it lacks Turbo Boost Max 3 support. Then, to inquire as to the turbo enabled or disabled status: cat /sys/devices/system/cpu/intel_pstate/no_turbo In order to see the driver: cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver It turns out up to now that Intel Skylake CPUs featuring Turbo Boost Max 3.0 (TBM3) may have not actually been working correctly for hitting this maximum frequency when the system is sustaining single-threaded workloads. Trying to follow this answer under Disabling Intel Turbo Boost in ubuntu: One of the bigger items is support for Skylake CPUs with Turbo Boost Max 3.0.
