Can't set appropriate frequency for my i7 5700hq

sergik82 · 2021-12-13 15:38:28

I'm trying to set appropriate frequency for the processor to avoid overheating...
Processor rate is 800... 3500MHz
I've managed to set 2600MHz and lower using cpupower... But I'd like to get 3100MHz...
I can set turbo boost off as well, but I don't need it...
Please any suggestions

The ArchWiki describes a manual method here and also shows how to check the valid frequency range. https://wiki.archlinux.org/title/CPU_fr … _permanent may also be useful.

fallowing these articles I counted with a problem
if I put this command into terminal
cpupower frequency-set -u 3.10GHz I just get 3.5GHz instead I wanted
but if it'll be cpupower frequency-set -u 2.6GHz everything work well

there is an output of cpupower frequency-info command

analyzing CPU 0:
driver: intel_cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 20.0 us
hardware limits: 800 MHz - 3.50 GHz
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 800 MHz and 3.50 GHz.
The governor "conservative" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 804 MHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes

what should I do to get the result that I need???

I know nothing about cpupower and I can't be bothered finding out about it just for you.

What does this say

cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies

And please read the links I supplied.

did you mean cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq ???

it's

So can you write the desired value directly into /sys/?

# tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq <<!
3100000
!

I got this message tee 3100000 > /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq

Why not try what I actually posted?

ok have a look

tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq <<!
3100000
!
3100000
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

But scaling_max_freq has actually changed?

Can you write 3100000 into cpuinfo_max_freq?

unfortunately there's no effect!!!

Head_on_a_Stick · 2021-12-14 20:45:17

Are there any errors or other output when you try? How do you know there's no effect? What was the exact command you used?

Remember: verbatim terminal content is always better than vague descriptions. And please use code tags for said content, it improves readability.

I used command that you asked me such as

 tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq <<!
3100000
!

as well as

cpupower frequency-set  -u 3.10GHz

and I showed you an output of

 cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq

So try

# tee /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq <<!
3100000
!

What does that do? If the value is unsupported I think you'll see "Permission denied".

I did it... Can show you again

# tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq <<!

3100000
# cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq

sergik82 · 2021-12-14 21:08:26

it seems the value is not saving by some reasons...

No, you didn't. Read my last post again please. Slowly this time.

EDIT: and please stop full-quoting unnecessarily, it makes the thread harder to read.

So why does this happen?

Head_on_a_Stick · 2021-12-15 05:57:59

Because 3.1GHz is not a supported setting.

How can I know what settings available???

Lone_Wolf · 2021-12-15 11:43:02

Try

# cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies

(tee gave permission error)
