Intel Speed Shift Technology Skylake

[unclewebb]

Just to clear up some information in this old thread, Speed Shift is a feature of Intel Skylake CPUs, mobile and desktop. It was originally only going to be available in Windows 10, 10586 or newer but because Speed Shift is a feature of the CPU, it can be enabled in any version of Windows. You could also enable Speed Shift in Linux by changing MSR 0x770 from 0 to 1. The easy way to do this in Windows is to download the latest version of ThrottleStop from TechPowerUp, click on the TPL button, check the Speed Shift option and hit Apply or OK. Once enabled within the processor, you can exit ThrottleStop and Speed Shift will remain enabled until you use Sleep, Hibernate or reboot.

ThrottleStop also lets you access the Speed Shift - Energy Performance Preference (EPP) setting. This can be adjusted from 0 to 255 which gives a user full control of their CPU so they can switch between full performance or maximum energy savings or anywhere in between.

If you are the type of person that always runs their CPU at maximum MHz then Speed Shift is not for you. If you usually use the Windows Balanced power profile then you should consider turning on Speed Shift instead. Compared to the Windows Balanced profile, Speed Shift does a better job managing the CPU and it will increase off idle performance.

Thats a nice feature, I have my power profile on balanced usually, didn't know how to turn Speed Shift on at first but after reading this post I got it working!
Thanks @unclewebb !

Woot glad I ran across this. This has been nagging at me for about a year now. I am a bit confused as I mainly run in Windows Balance...you suggested turning on Speed Shift instead....what exactly are you meaning...I enabled speed shift but is there another step I need to do?

Thanks

You just need a Skylake CPU and ThrottleStop, once turned on speed shift you can exit the software as unclewebb said above.

That is what I thought...but wanted to make sure since I just enabled it, the way I was reading it was it was done once enabled or use it instead of windows balanced power plan.
