[idkfa] Posted May 14, 2012 Share Posted May 14, 2012 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 [idkfa] DSDT.txt Link to comment Share on other sites More sharing options...
