It works for me now, it was some error I did when changing the plist file, think I forgot to touch the extensions folder (but I booted with -v -f so it should not matter right?).

Running on 1162 mV on a Q6600 but even if the cpu would run at lower voltages it's impossible to go under 1162

However, I save almost 15 watts at full load using the lower voltage.

Chaps,

Quick question - I'd like to modify the source code to lock in specific VID and FIDs for the Pstates on my T8300, as well as enable SLFM. My chip works quite well at .9V for 1GHz and 0.975 for 2.4GHz and thus I'd like to manually set these levels in on VoodooPower. The problem is I cannot locate the right function calls inside intel.cpp and the amd way to do this does not look similar

Any pointers as how to do this?

Thanks

Hi,
it seems to work on my L7500 x61s but i can't get rid off "com.superhai.driver.GenericCPUPowerManagement"
it's still loaded but i cannot find the kext file!

here's my log :

BE CAREFUL if you OC the CPU by FSB and lowered the Multi in your BIOS.
BIOS PART:
My C2D 2.66 (FSB 266 = default, Multi 10 = default, has 5 P-STATES 4...0 6,7,8,9,10* Multi) running at FSB 333=OC, Multi 9=lowered
Gives OC of 3.0 GHZ (9*333 FSB).
If i try to OC more in BIOS by 333 FSB (OC) and Multi 10*(default) = 3.33 GHZ =  FREEZE (even with more CPU VIDs)

MAC OS X PART:
Without VP the CPU runs as set in the BIOS : FSB 333 * 9 Multi = 3.0 GHZ.

If i kextload VoodooPower or MiniPower without any change in the plist that will happen:
Running perfect until high CPU% load cames up and VP switch P-States down:
P-State 4 > 3 > 2 > 1 > 0 FREEZE.
If VP tries to switch to highes P-STATE (0=Multi 10) CPU is too much OC: 10*333 FSB =3,33 GHZ = FREEZE. That will happens even if the VID(mVolts) are set much higher for OC.

To avoid that, you must disable the highest P-STATE 0 by setting PstateHighest = 1 in the .plist.
Now the CPU runs as without VP from P-STATE 4= 6*333 = 2.0 GHZ up to PSTATE 1= 9*333 = 3.0 GHZ. Stable as without loading/using VP.

An new check in the initialisation of VP may warn, by probing FSB=orig. CPU default (200/266/333) or not (333 FSB on 266 FSB CPU Type= Multi changed=warning)

Since 10.5.8 it is needed to use AppleIntelCPUPowermanagment.kext for proper sleep. Using the Applekext results in much higher CPU Temperature, so Powermanagement does not work with the kext.
Using Voodoopower kext results in lower CPU Temperature, but not as low as using NONE of both kexts. Why is that?

If i use NONE of both kexts, my CPU Temp sinks as low as 30C. If i use Voodoopower and the Apple kext together, the CPU Temp rises about 6C. That wouldn't bother me much, but the fan-noise gets to a disturbing state when the PC is idle

Is there a way to get the old powermanagement back when using both kexts? I already set "CStateControl=True" in the Voodoopower.kext plist, but it didn't help.


Thanks!

Why not use the native Speedstep Control of OSX?

[mitch_de]

Because its not speedstep. OS X manages the cpu powermanagement in an other way, which isnt much effective - even if it works on an OSX86.
If its not working (AppleIntelCPU/ ACPI-SMCPlugin dont fit to the OSX86 Modell) you get much higher CPU temp - even compared without Voodoopower.

So AppleIntelCPU really works only on real Macs. On non Macs you get more/less worst cpu powermanagement.
(Depends on: smbios "MacModell", CPU Type, Mainboard hardware powermanagement).
Without any speedstep control (Voodoopower) my Gigabyte MB runs really cool by using the other , hardware/bios based(does his work without any drivers alone) cpu powermanagement (C1E,..).

[riws]

I'm not so sure about this,  with VoodooPower it throttles just more. I have the same battery durability with the native one.

[ApexDE]

@ mitch_de

True. The Bios Powermanagement worked like a charm. I hope the Voodoopower.kext gets C-State Control soon or we can get rid of the AppleIntelCPUPowermanagement.kext without losing sleep.

Hi mitch

are you saying the BIOS controls/triggers the C1E state without need for drivers?

Also if you have defined p-states in DSDT then surely AppleIntelCPUPM is giving you speedstep?
~EDIT~ It's controlling muti' and VID which is speedstep no?

Admittedly it's far simpler to use voodoopower !!

AppleIntelCPUPM and Coolbook looks simpler.

I presume this works as long as AppleICPUPM is loaded?
wouldn't matter - for - example - if AICPUPM is reporting P and C-state errors

CoolBook is not working for me - no CPU related values are being read. Maybe because of the changes I've made the _PR part of DSDT?

[mitch_de]

Coolbook doesnt use Speedstep (EIST) funktion. It does it its own way (by own code).
I asked the dev last year about that. He told me that he dindt use the HW function EIST(speedstep) of that cpus supporting speedstep.
I would not use that.

I am investigating the sleep issues with my mainboard GA-EP45-DS3 (currently i only use the AppleIntelCPUPowermanagement.kext)
Sometimes my system hangs when going to sleep. Since 10.5.8 it even hangs once-in-a-while when it should wake up. Someone gave me the hint to disable EIST in the BIOS.

With the AppleIntelCPUPowermanagement.kext my System sleeps/wakes fine. Which seems to make sense to me: the kext obviously turns OFF all CPU powersaving features. So, no powersaving features are used when the system goes to sleep. But my goal is to get rid of the AppleIntelCPUPowermanagement.kext as it heats up the CPU quite a lot.

My next step would be to turn off EIST in the BIOS and use the Voodoopower.kext again, which leads to my questions

To which state does Voodoopower turn the CPU when the system goes to sleep? If my theory is true, it should be running without powersaving (e.g.  lower frequency) when going to sleep for proper sleep/wake.

Does Voodoopower's speedstepping even work when EIST is disabled in the BIOS?

NO! Voodoopower uses EIST(speedstep) funktion, needed if you want speedstep.

hi guys, i don't know why my mac can not install the voodoopower kext. It's just crashed immediately after using KextHelper to install voodoopower. I have to turn off power, then I check Extensions folder, voodoopower kext never been in there. If you guys have met this issue, please help. Or please give me a link where i can sort it out. I've searched around, but i can't find the solution.

My Hacinstosh specs:
Dell Studio 1735, iDeneb 10.5.8, Intel Core 2 Duo.
