Locking CPU to lower frequency or disabling Turbo Boost?

[Bernard]

Is there a way to lock the CPU frequency or cap it at a certain number? Or disable Turbo Boost?

On the Core i chips, Android-x86 seems to keep them running at max which translates to a good amount of heat and fast draining battery. Just curious if anyone's got something to work.

Same for me on Bay Trail.

For Intel CPUs, setting intel_pstate/no_turbo should work. Try this (as root):
echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo

To make this change permanent, you'll have to add the line above to Android's init script.
(unless there's a way to add this as a kernel parameter, couldn't find any).

Awesome, thanks. Will try later.

I'm guessing you measured it after using CPU-Z or something. Did you ever try a kernel tweaking program like TricksterMod? Guessing they don't work on Android-x86.

Just got around to testing this. Works great, caps the i5-4200U at 1.6GHz, keeps it cool, and prevents the fan from ramping up.

Thanks man!

Amazing! It works! By the way  @Povilas Staniulis

On your sp3, do you have a touch bug which the screen sends false touch data resulting the system thinks you are constantly touching a point but actually you didn't?

I don't have a SP3. I have an Asus T100TA (bay trail).

is sound working  for you?

Povilas,

Is there a way, above and beyond just disabling turbo boost, to throttle cores? With turbo boost disabled, it's better, but it still will max the CPU at 1.6 GHz and heat up more than I'd like.

I'd like to cap the cores at a specific frequency. Any of the kernel tweaking programs work? Or code?
