Not working on Q6600 overclocked to 3.0GHz on Gigabyte P35-DS4

Thanks!

Can you please post the output of  sudo dmesg  after loading the kext? Thanks. Also check your BIOS whether it has speedstep enabled.

[mitch_de]

Seems to be very "cool" also for desktop users with overclocked CPUs. If nothing to do, CPU can cool down more than with C1E (in BIOS enbaled/disabled like enhanced speedstep enabled/disabled).
Q: Does CE1 CPU engergiesaver works beside speedstep (bios of mainboard manage that)  or does it nothing running OS X ?

PROBLEM:
Aftera view minutes working speedtep app quits (no more in menu).
Only that message in the syslog, no dmesg of your .kext.
login[2438]: DEAD_PROCESS: 2438 ttys000 (i know that 2438 was speedstep).

Now i will try CTB2 running insted of speedstep.

Working since 15 minutes without quitting like speedstep.
Only asking every 5 Min for admin pwd, i made the same trick to (sudo .....) as hint above some posts.

[wingrunr21]

This is an update from my previous post.

Using SpeedStep.app is a lot better than the CPUThrottler. Mouse lag is non-existent or at least not noticeable except for when then CPU changes frequency.  There is still a slight lag but otherwise rather smooth.

One interesting thing to note is that the kext is picking up an 800 mhz throttle level and a 2601 mhz throttle level.  Neither one of these levels work.  Here are the levels that do work: 1200 1600 2000 2600.

[mitch_de]

Now 2 hours later, all is OK. CTB2 is running and has not quit as SpeedStepp app.
Also stepping has worked all the time without any problem.

The following items in BIOS are enabled:
CPU Enhanced Halt (C1E)
CPU Thermal Monitor (TM2)
CPU EIST Function

Also, same problem with E7200.

For some reason SpeedStep.app dosent like me beta app works but with bugs same sound problems but sound is ok when i switch freq manual in terminal so is not kext fault, only bug i found in kext is 800 & 2401 freq, both dosen't work. Also i notice a temp increase on stock freq 2400 ~51 C was never before more then 44 C
BTW that "cat /dev/urandom > /dev/null" keeps 1 core of cpu in 100%  
"sudo dmesg | grep IntelEnhancedSpeedStep" returns nothing on me.
Pastebin results

[mercurysquad]

Hey people, please keep issues separate, ie. if it's an issue with one of the speedsteps apps, it is not in my control   So if you are having problems, please close the speedstep apps and try throttling manually using the terminal (sysctl command).

Primarily I am testing the .kext because that's what's new. tuxx is working on improving SpeedStep.app (which will also support voltage changes). Will keep you all posted.

New kext will come tomorrow with a lot of the issues fixed. Please keep the test reports coming! Thanks.

[lovedahackintosh]

eagerly waiting the next version of this. i tried it on my inspiron 6000 (against your recommendation) and wasnt too successful. i am now using your beta 9.2 kernel from the other thread as my default as it is the only thing that FINALLY fixed my sound... even if i can only throttle down to 1ghz.

any chance this (as opposed to the custom 9.2 kernel) will eventually work for sse2 cpus?

Thanks!

[rhyguy]

This doesnt work, as well as every other sppedstep solution out there

IntelEnhancedSpeedStep: WARN  There was an error while getting PState array from ACPI

Dell inspiron 530, intel q6600

[zillac]

Works great here on Thinkpad T60p, C2D T7200, "1000 1333 1666 2000" all works.

Thanks for the great work.

[uuid]

Q6600 on GA-P35-DS3L:

Kext loads and works fine when NOT overclocked. Available Frequencies are 1600 and 2400.
Load: http://pastie.org/249044
DMESG: http://pastie.org/249045 (and so on)

When OC'd, I get the often reported "IntelEnhancedSpeedStep: WARN There was an error while getting PState array from ACPI"

Thanks for the hard work! This is turning out to be a great kext!  
edit:
Sleep/resume works (did before)
Playback is smooth (3 HD videos simultaneously)
Changing frequencies between the two values seems to work (what is a reliable way to determine actual freq?)

the most reliable way is to read the "kern.cputhrottle_curfreq" value using sysctl. just do:

sudo sysctl -a kern.cputhrottle_curfreq

Question:
Does the new speedstep.kext trottle allone (after setup as dynamic)  or does it need an running App like CPUThrottler / SpeedStep too and stops throttling when no CPUThrottler/SpeedStep is running?
I dont need (always) an feedback how fast the cpu is running (App Window/Menue).

Would be great if , if it is possible to include the throttling in the speedstep.kext itself and use CPUThrottler only for setup/changing setup.

[mercurysquad]

New kext out, check 1st page.

Kext does no throttling on its own. Either do it via terminal, or via one of the apps. In the future we may add autothrottle support.

SSE2 users: This will work but clock will be messed up. Even on my modified 9.2 kernel. Next beta 1.2.1 probably this evening will support sse2 with 9.2 rtc fixed kernel also, but no sleep with that unfortunately. A new universal 9.4 kernel with fixed clock+sleep is in the works as well.

Cheers.

It works! Amazing, thanks so much! I'm running my Q6600 at 1.2 volts / 1600 MHz at the moment, and seems to be stable. Anything specific that I should test?

[mercurysquad]

SSE2 Users - version 1.2.1 now supports SpeedStep kernels with rtcfix! Set KernelFeatures to 1 in Info.plist to enable it!

[THe KiNG]

Well the new kext dosen't work on my lappie stuck on 2401 MHz and is the only freq reported!
On Pc same 2 value, only thing that is changed to me is the debug info on boot.
Waiting for new beta to test.
Keep up the good work, I can see the light XD

[r_o_o_s]

I have a Dell D830 and I have now done som more testing. (system/kernel info below)
The bios setting dynamic accelleration seems to affect the kext.

with the old one (1.0 or 1.1 or whatever it was)

DA off: gives me 5 modes 800,1200,1600,2000,2001 (neither 800 nor 2001 works)
DA on: gives me 4 modes 800, 1200,1600,2000 (800 doesnt work, guess i need fixed kernel)

with 1.2.1b
DA off: gives me 3 modes (1200,1600,2000)
DA on: gives me 1 mode (2001)
Messing with kernelfeatures causes kernel panic


Sleep works with both kexts
Sound is affected the moment one changes mode, not else
Have a look at the end of this post for interesting voltage behaviour
