CPU FREQUENCY SCALING TOOL [SOLVED]

[pp4mnklinux]

Morning EveryOne:

Some days ago, I changed my processor, from a i3540 CPU to a i5680 and it works faster, much faster, but here my problem come.

Till now, I used the CPU FREQUENCY SCALING TOOL, and I can choose different configurations. I tried to do this with my new processor and this options don't appear (look photo) it says I must use the appropiate drive...bla...bla...bla.... and I can't choose any option to modify the percent of the processor use.

What must I do? Can u give me the driver for this processor and explain me what I must do??

THANKS IN ADVANCE and happy weekend.

These days, i3 & i5 cpus run much better under intel_pstate using powersave than other drivers. Have you disabled it? That powersave option is the equivalent of the old ondemand driver, but better.

Hi, ozsouth.- I don't know how to verify if I deactivated it, and, in case, how to activate it again.

Can u help me, please, to activate it again.?=?= Thanks a lot.

have a nice day, my friend.

@pp4mnklinux :-

I'll back Oz up on this one.

My old desktop had a 15-yr old, dual-core AMD Athlon64 X2; it was quite happy using the Frequency Scaling tool. Since switching to this new HP desktop - 9th-gen, "Coffee Lake" quad-core Intel Pentium 'Gold' G5400 - I took the advice to leave well alone, and let the CPU do its own thing. It's functioned quite happily like that ever since, though it runs pretty cool for an Intel chip anyway; my averages are between high 30s/low 50s (depending on what I'm doing).....a LONG way off throttling point.

Mike.

@ozsouth really funny

You can try what is described on the first answer described in https://unix.stackexchange.com/question ... ern-pstate

I have tried this in the past (go to the puppy package manager to get that application or run in terminal pkg get linux-cpupower), for something else, but personally did not notice any significant difference on a 4th gen i5.

You can also try to undervolt the CPU with this tool I've just posted

@pp4mnklinux -
To check pstate status, run the following in a terminal: dmesg | grep pstate
If 'disabled' does not appear, then intel_pstate is engaged & you need to decide
which throttling system you want to use (see later).
Different settings of any cpu management tool can significantly affect results.
Some setups may go better with acpi-cpufreq, as @norgo suggests.
Under that, 95% up-threshold will run cool but be slow to respond to videos etc.
30% up-threshold will do the opposite.
Intel_pstate can be tweaked too - I set my maximum & minimum % to achieve
heat vs responsiveness balance. I won't detail that yet.

If you want to try intel-pstate, first delete /etc/init.d/wcpufreq (if present),
then reboot & don't run the cpu frequency setting tool.

If you want to run acpi-cpufreq, run the cpu frequency setting tool, make your
choices, then append your grub (or grub2) .cfg - kernel (or linux) line with
intel_pstate=disable, then reboot.

Thanks a lot to everybody to answer me.-

That is one of the reason that make me love puppy, it's community.

Have a nice day, my friends.
