Samsung Tools

CPU frequency scaling

Asked by Will Shackleton

Hi
What happened to the CPU frequency scaling mode, as I believe the early versions of the samsung tools used to support this.
I'd like to contribute to this project by writing this feature into the samsung tools, adding a key shortcut to it; is there any reason why I shouldn't?
I have the Samsung N110, and I assume most other samsung laptops support this feature.

Hi,
sorry for this very late answer.

Yes, Samsung Tools used to support CPU frequency scaling mode in its early versions, but I dropped it because it was pretty useless.
I cannot see any valid reason to use a CPU governor other than "ondemand", so I decided to replace it and add support for the overclock mode available on pretty much all of the Samsung laptops (normal mode, silent mode, overclock mode... which honestly also seem pretty useless to me but required from many users).

I suppose. My main use was to slow it down to reduce the temperature, but it did get quite slow.

Is there any chance to implement this as an option?

CPU frequency scaling Yes/No?

That way I can throttle it via the F12 button but ondemand for those that don't want it.

(or can you let me know how to implement it myself? cpufreq performance/powersave does not work)
