PowerManagement with Q9650 and 560TI

[[idkfa]]

Hi everyone,

 

I'm a long-time reader and have gotten quite a bit of knowledge by reading InsanelyMac, so first thank you everyone for posts!

 

After my HD and my backup HD both broke down on the same day, I had to recreate my Lion installation from scratch. Everything is working so far, but I'm currently puzzled about the CPU power management.

 

My hardware:

Gigabyte GA-EP45-DS3 with F10e bios

Intel Q9650 (not overclocked or anything)

eVGA nVidia GTX 560 1GB

 

My system identifier is MacPro4,1 to get AppleGraphicsPowerManagement to work. Therefore, I can't really switch down to the more correct MacPro3,1.

My CPU temperatures are quite high; in Lion (10.7.4 right now) they are about 10°C higher than what I get in Windows (see attached screenshots). I see the voltage in Windows is lower, however I am unsure whether that small difference will yield in 10°C.

I've experimented with various DSDT patches I found, however either they didn't seem to work or they fixed the CPU's multiplier at 6 (where it is supposed to change between 6 and 9).

 

About the screenshots:

hwmonitor.png shows temperatures without any GeneratePStates/GenerateCStates in boot.plist; hwmonitor2.png with all settings enabled.

Currently, my settings are:

 

<key>Boot Graphics</key>
<string>Yes</string>
<key>Default Partition</key>
<string>hd(0,2)</string>
<key>EnableC2State</key>
<string>Yes</string>
<key>EnableC3State</key>
<string>Yes</string>
<key>EnableC4State</key>
<string>Yes</string>
<key>EthernetBuiltIn</key>
<string>Yes</string>
<key>GenerateCStates</key>
<string>Yes</string>
<key>GeneratePStates</key>
<string>Yes</string>
<key>Graphics Mode</key>
<string></string>
<key>GraphicsEnabler</key>
<string>Yes</string>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>npci=0x2000 darkwake=0</string>
<key>Legacy Logo</key>
<string>Yes</string>
<key>Theme</key>
<string>LoginToLion</string>
<key>Timeout</key>
<string>2</string>
<key>USBBusFix</key>
<string>Yes</string>

 

Attached is my DSDT (with all the fixes I'm using now minus P-States/C-States, as I don't know what to put there right now.

Btw, if you have any other suggestions/fixes about my DSDT not related to CPU power management, feel free to post them, too

 

 

Thank you in advance
