[SOLVED] How to disable throttling?

[ene_dene]

I have laptop with the following processor:

ed@killers2:/proc$ cat cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Pentium(R) M processor 1.70GHz
stepping : 6
cpu MHz : 1694.660
cache size : 2048 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe up est tm2
bogomips : 3391.35

I use boinc - einstein@home so I need that my laptop works 100% all the time, with no powersaving, but I can't stop cpu throttling:

ed@killers2:/proc/acpi/processor/CPU0$ ls
info limit power throttling
ed@killers2:/proc/acpi/processor/CPU0$ cat throttling
state count: 8
active state: T2
states:
T0: 00%
T1: 12%
*T2: 25%
T3: 37%
T4: 50%
T5: 62%
T6: 75%
T7: 87%
ed@killers2:/proc/acpi/processor/CPU0$ cat limit
active limit: P0:T3
user limit: P0:T0
thermal limit: P0:T3
ed@killers2:/proc/acpi/processor/CPU0$ cat info
processor id: 0
acpi id: 0
bus mastering control: yes
power management: yes
throttling control: yes
limit interface: yes
ed@killers2:/proc/acpi/processor/CPU0$ cat power
active state: C2
max_cstate: C8
bus master activity: 00000007
states:
C1: type[C1] promotion[C2] demotion[--] latency[000] usage[00000010] duration[00000000000000000000]
*C2: type[C2] promotion[C3] demotion[C1] latency[001] usage[00000882] duration[00000000000006781310]
C3: type[C3] promotion[C4] demotion[C2] latency[085] usage[00000000] duration[00000000000000000000]
C4: type[C3] promotion[--] demotion[C3] latency[185] usage[00000000] duration[00000000000000000000]

So from that you can see that my comp is not using all the cycles.
I saw a suggestion that I should type:
sudo /usr/bin/cpufreq-selector -g performance
but the output is:
No cpufreq support

Please tell me how to disable throttling in some other way.

There is a 'service' daemon called "powernowd" running that handles this. You can stop it with a command sudo /etc/init.d/powernowd stop
but there may also be a way to do it from the GUI.

That worked for me. Check your CPU speeds afterward, and it should be full clock at that point. You can re-start it with "start" as your parameter in the above command.


EDIT: Mind your temps when you do this, especially on a laptop. Your CPU will run quite a bit warmer, and your laptop may not have been designed to dissipate that much heat without expecting some cooldown period!

Unfortunately I haven't got such service installed.

Your PC is probably using the speedstep-centrino module for throttling.

Try this:
lsmod | grep speedstep

If you have the module running, you can stop it from loading by blacklisting it. You'll see how to enter it when you open the file:
gksudo gedit /etc/modprobe.d/blacklist

Yes, that's true. I turned of acpi from loading and that solved the problem. I'll try it this way to, so I don't need to turn of acpi.
Thank you.
Btw, I can't find "mark this thread as solved".
