Try this: 


#!/bin/bash

echo "CPU 1: $(cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq)"
echo "CPU 2: $(cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq)"
echo "CPU 3: $(cat /sys/devices/system/cpu/cpu2/cpufreq/scaling_cur_freq)"
echo "CPU 4: $(cat /sys/devices/system/cpu/cpu3/cpufreq/scaling_cur_freq)"

I get 'no such file or directory'.

what happens when u enter in ssh 


cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

 

In ssh i still get 'no such file or directory'.

 

I had a look through the directories and the cpu0, cpu1, cpu2 etc... folders don't have a cpufreq folder. I do have /sys/devices/system/cpu/cpufreq/ but it's empty.

 

Does that mean I'm missing the driver?

Hi, I'm having the issue of my CPU frequency not scaling down too. I've tried the intel_pstate=disable in syslinux.cfg to no avail. I've also tried toggling all power/scaling related functions in the BIOS with intel_pstate enabled and disabled. Can't figure out a solution. 

 

grep -m 1 'model name' < /proc/cpuinfo:

model name      : Intel(R) Xeon(R) CPU           E5405  @ 2.00GHz

 

If anyone has a solution for this generation of Xeons it would be greatly appreciated.

 

Thanks!

I've had the same issue with this family of processors, Been watching / searching for a resolution for a couple years, havent had any success yet...

These older models use the acpi-cpufreq driver, no config is necessary in unRAID, you just need to have SpeedStep enable in the bios, e.g.:

 

 grep -m 1 'model name' < /proc/cpuinfo
model name      : Intel(R) Xeon(R) CPU           X3350  @ 2.66GHz
 grep MHz /proc/cpuinfo
cpu MHz         : 2000.000
cpu MHz         : 2000.000
cpu MHz         : 2000.000
cpu MHz         : 2000.000

grep MHz /proc/cpuinfo
cpu MHz         : 2667.065
cpu MHz         : 2667.065
cpu MHz         : 2667.065

:/ That's unfortunate. I just did an electricity cost calculation and it'll cost me $26 (Canadian) per month to operate it without frequency scaling.

Thanks Johnnie, unfortunately enabling Enhanced Intel Speed Step in BIOS doesn't seem to work for me. I've tried toggling that along a number of other settings with no luck. I've also tried updating the mobo firmware and BIOS and that hasn't worked either. I hope they can figure out a solution.

If you can read the consumption, you could maybe test it, check Watt while doin 100% CPU stuff, and while its idle, if theres a difference (lower Watt when idle) , its working, i guess.

 

This might surprise you, but with or without Intel Speed Step or other technologies working, the CPU will draw different amount of power if at 100% or at idle. Even if the processor performs a busy-loop at idle instead of doing an old-style sleep while waiting for the next interrupt, the power consumption would still depend on actual amount of processor modules in action - a busy processor uses multiple ALU, address translators etc while an idle processor does not.

One thing I forgot to mention, you want to make sure your CPU is using the correct driver, older pre-Sandy Bridge Intel CPUs use the acpi-cpufreq driver, Sandy Bridge and newer use the intel_psate driver, another example:

 

This is a Nehalem Xeon, last generation before Sandy bridge:

 

# cat /sys/devices/system/cpu/cpufreq/policy0/scaling_driver
acpi-cpufreq

 

# grep -m 1 'model name' < /proc/cpuinfo
model name      : Intel(R) Xeon(R) CPU           X3430  @ 2.40GHz
# grep MHz /proc/cpuinfo
cpu MHz         : 1220.163
cpu MHz         : 1213.410
cpu MHz         : 1208.500
cpu MHz         : 1288.776

If yours is using the correct driver the problem is the board/bios, if not there might be something you can do.

I've updated to 6.4 and 6.4.1 without any change.  I've also Enabled, Disabled, Enabled speed step in the BIOS, the intel_pstate,  and nothing seems to have helped.   I believe I have the latest BIOS for my board (Intel S5000 Server Board).  I'll readily admit that this is all above my pay grade!

 

To summarize again, my tests:

grep -m 1 'model name' < /proc/cpuinfo
model name      : Intel(R) Xeon(TM) CPU 3.20GHz

                                      
grep MHz /proc/cpuinfo
cpu MHz         : 3191.861
cpu MHz         : 3191.861
cpu MHz         : 3191.861
cpu MHz         : 3191.861
cpu MHz         : 3191.861
cpu MHz         : 3191.861
cpu MHz         : 3191.861
cpu MHz         : 3191.861
                                      

 

I am just putting up with it for now, unless someone has other suggestions.  The strange thing for me is that it was a power outage in early January that seems to have caused this behaviour (I never checked this before, so I'm not certain).  I was given the warning before about the CPU not stepping down, but the fans (and I'm guessing the CPUs) weren't running full, noisy speed.  Only since the power outage have the fans (and presumably the CPUs) run at full speed .

 

I don't know if it's related, but I'm also experiencing issues with Plex; I've run into many issues with newer TV episodes.  The episodes play fine as long as the Plex client is connected to my local network (wired or WiFi), but remote clients are hit and miss.  I probably need to ask at the Plex forums, but would the CPU not stepping down perhaps prevent remote connections with Plex?

the intel_pstate

That's not the correct driver for your CPU.

Not likely, and certainly not related to unRAID since it runs from RAM, so a reboot/power loss wouldn't change anything in the config, at most the board could have done a cmos reset and lost some setting.

 

I still think it's a board/bios issue expecially since it doesn't even correctly identify the CPU model, only the frequency.

Calling this returns "no such file or directory". Seems to me like the driver isn't loading for whatever reason. Even though the correct settings are set in BIOS.

 

I think my Xeons are Harpertown not Nehalem. I dunno if that matters.

Mine are Harpertown.

Mine are Harpertown.

 

Output of:

cat /sys/devices/system/cpu/cpuidle/current_driver

and

 

cpufreq-info -d

 

If this last one has no driver see if it loads manually:

 

modprobe acpi-cpufreq

And then run cpufreq-info -d again.

Here ya go!!

none
root@Tower:~# cpufreq-info -d
root@Tower:~# modprobe acpi-cpufreq
modprobe: ERROR: could not insert 'acpi_cpufreq': No such device

No diver is loaded, so that's why it doesn't work, the driver should load automatically if the board bios correctly identifies the CPU, not sure if it's possible to load it manually.

CPU info, I dont beleive the Supermicro board has any issues with the CPU's...Not sure how I would check that!!

root@Tower:~# grep -m 1 'model name' < /proc/cpuinfo
model name      : Intel(R) Xeon(R) CPU           E5440  @ 2.83GHz
