BKHD N100 and Random Frequencies

[pscar13 (Phil SCAR)]

Hello,

Since I installed IPFire on my N100 miniPC, I’ve been experiencing random frequencies at startup.

My machine is a BKHD 1264NP with four 2.5Gb ports.

I’ve tried several optimization tips found on forums by modifying PL1 and PL2 or ACPI in the BIOS.

I also tried the cpufrequtils add-on.

But apart from slowing down the system, the frequency doesn’t really stabilize.

I don’t think this is really a problem.

But does anyone have this type of machine and been able to find the correct BIOS settings?

cpufrequtils is dead → nowadays it’s cpupower

True but until core196 our addon is still called cpufrequtils even if the scripts use cpupower.

git.ipfire.org Git - ipfire-2.x.git/search

With core197 this addon will dropped and the scripts are always installed.

@phil:
Your freqencies looks normal for a N100 which use Intel pstate and switch the frequency depending on cpu load and temperature.

With Pstate you can only set powersave or performance but this not mean you get a stable frequency.

Thank you.

But how can we explain the significant frequency changes during the reboot that occurs every morning at 4:30 a.m.
The charge and temperature must be roughly the same at this time.
