Turbo boost technology is an Intel invention that is used in their Core i5 and Core i7 series processors. Summing up What is Turbo Boost Technology?.Does Turbo Boost Damage Your Processor?.I do not know the implications of 'bios_limit', because it works fine in Windows, but is there a way to change this safely so that I can use both the standard 2.3 GHz and the Intel Turbo speeds? Turbo goes up to 3.2 GHz on this one. Product: Intel(R) Core(TM) i5-6300HQ CPU 2.30GHzĪnd $ cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit Any suggestions or pointers would be very helpful, thank you! This is really a problem for me, and I don't know why this is happening. The governor 'ondemand' may decide which speed to useĬpufreq stats: 759 MHz:19.19%, 1000 kHz:80.81% (673)

Something is also off with cpufreq-info, it reports steps of 1 MHz and 759 MHz? That doesn't make sense to me here's the report for CPU0: analyzing CPU 0:ĬPUs which run at the same hardware frequency: 0ĬPUs which need to have their frequency coordinated by software: 0Īvailable frequency steps: 759 MHz, 1000 kHzĪvailable cpufreq governors: conservative, ondemand, userspace, powersave, performanceĬurrent policy: frequency should be within 1000 kHz and 759 MHz. Under load, indicator-cpufreq only shows 0.76 GHz. For 1M digits of pi, it takes 25-26 seconds, whereas my Windows install on the same computer takes 12-13 seconds. So I downloaded Super Pi and ran a single threaded benchmark. Lintian takes extremely long amounts of time when checking packages etc. I have installed Ubuntu 15.04 on it, and I've been noticing that the CPU performance is much slower than I expected, especially when I run make even when using all four threads. I have a Dell Inspiron i7559 laptop with a Core i5-6300 HQ and an NVIDIA GTX960M GPU.
