CPU running with top speed all the time

English Hardware
#1

Few days ago i installed a fresh Leap 42.2 so i can use amdgpupro with my new AMD RX 480.
Installation was standard as suggested from installer, nothing special, except the
amdgpupro driver 16.50. All went well and the system is running like a charm.
Unfortunatelly conky, which i use to monitor my system, wasn´t working at that
time, because they changed their system. After adjusting conky 3 days later i
noticed, that the cpu was running at full speed all the time without ever clocking
down.
I use a Xeon 1230 v3 with 3.3Ghz max speed and 3.7Ghz turbo.
The cpu is working now with Leap 42.2 between 3.5Ghz and 3.69Ghz never clocking
down, even if no load is present for the system.(Init 3 for ex)

There is nothing wrong with intel speed-stepping or the mainboard, because the
cpu is clocking well up and down on a parallel installed Win 7.

Funny thing is, that with an ubuntu 16.04 and the same amdgpupro driver installed for
testing purpose, the cpu shows the same problem, with exactly the same high Ghz
as with Leap 42.2.
Can anyone without the amdgpupro confirm, that Leap 42.2 is clocking the cpu well
up and down?
Can anyone with the amdgpupro confirm, that the cpu is running on turbo speed on
their system as well? Thx

Hi
Disable intel_pstate and see if that helps (switch back to acpi), add the following via YaST2 -> System -> Bootloader -> Kernel Parameters tab to the Optional Kernel Command Line Parameter, between the silent and quiet words;


intel_pstate=disable
#3

Wow great, that did the job, thank you very very much.
The cpu is now clocking up and down like it should be.

It took a bit to insert the command, because yast in KDE as well as yast on command line
was freezing, when entering the kernel parameters. I insert the command then directly in
grub on boot. Thx again.

#4

Inserting at boot in grub is a one time thing the setting is lost on next boot you must do it via Yast or grub-conf to make it permanent

#5

Hi
I would suggest some research on intel_pstate configuration, technically going forward that’s what should be used, but might be worth a bug report…?

#6

Ah ok, didn´t know that. I try to find a solution then to avoid yast from freezing. Maybe it´s because ubuntu is still installed on my box.

I don`t know if Leap 42.2 is causing the cpu behavior or the amdgpupro driver, so no good idea right know for a bug report.

But thanks again for both of you for your great support.

#7

Well, you could add it to the line at boot, just as you did, then launch the Yast Bootloader module, then add that to the boot line in there.:wink:

#8

Coming in to report that this identical problem happened to my Leap 42.2 installation with an Intel i7 4970K.

Adding “intel_pstate=disable” to the kernel parameters also solved the problem for me.

cpupower frequency-info now shows “driver: acpi-cpufreq” and “available cpufreq governors: ondemand performance”.

Previously, available cpufreq governors read, “powersave performance”. Powersave was the “current policy” but it was not throttling the CPU correctly.

Ditto here. I had forgotten where I had seen it - thanks.

Is this being worked on?

Hi
Someone with the hardware would need to raise a bug report… I don’t have any intel cpu’s here that are affected…

i have the same problem , conky show constant turbo speed between 2.50 and 2.60 Ghz

Leap 42.1 is more responsive .
after 3 times zypper dup to 42.2 , i always reverted back to 42.1 .

thnx for any help .

#13

forgot to mention , in comparison to 42.1
temp is running hotter when idle , both with or without intel_pstate disabled

I had wondered about this area as my pc seems a bit noisier since leap went on it but maybe it’s time for a new fan.

Hi
Perhaps you should wait for a release from the kernel developer rather
that install a kernel from a home users repo…?

But, hey it’s your system…

Hi
Seems to be switching fine and on powersave, could need a clean out,
but keep an eye on the sensors output and fan speed…

Thanks for the reply. The cores are running at 24 or 30C. The machine lets out a horrible noise when the cpu is too hot - I’d better re enable the pc speaker in case that ever happens again. I disabled it because of some audio issues. No info on fan speed. HP have used the right sort of heat sink - blows through rather than onto it but as it’s cowl is part of the main heatsink it’s a pig to clean.

After testing some more , including 4.10.1-2.1 from kernel stable repo , i gave up and reverted back to 42.1 , i’m going to skip 42.2 .
Thanks any way .
