For the life of me, I cannot get speedstep fully working on my system. Turbo doesn't work at all as far as I can tell. ML 10.8.4 i7 740QM (1.73 Ghz) 8Gb DDR3 667 AMD HD5870M Using MBP 6,1 SMBIOS After generating my SSDT with ssdtPRGen, and another attempt using MaciASL, with the correct values of 45W TDP, 2390 Turbo, this is what Chameleon shows me on bootup: Read HFS+ file: [hd(0,2)/Extra/SSDT.aml] 713 bytes. ACPI table not found: SSDT-1.aml FADT: changing PM_Profile from 0x00 to 0x02 FADT: ACPI Restart Fix applied! Found ACPI CPU: CPU0 Found ACPI CPU: CPU1 Found ACPI CPU: CPU2 Found ACPI CPU: CPU3 Found ACPI CPU: CPU4 Found ACPI CPU: CPU5 Found ACPI CPU: CPU6 Found ACPI CPU: CPU7 P-States: min 0x7, max 0x9 SSDT with CPU P-States generated successfully RSDT: Added 2 SSDT table(s) FADT: ACPI Restart Fix applied! Added 2 SSDT table(s) into XSDT I'm only getting 2 P-States here, with the highest one being my CPU's base frequency, 1.73 GHz. When I attempt to see what P-States have been reached with AppleIntelCPUPowerManagementInfo.kext, using: cat /var/log/system.log | grep "AICPUPMI:" I get this output: Jun 21 12:32:10 localhost kernel[0]: AICPUPMI: CPU P-States [ ] Attempting to use MSRDumper gives me this output: /Users/trey/Desktop/MSRDumper.kext failed to load - (ipc/mig) server died; check the system/kernel logs for errors or try kextutil(8). I am baffled. I am going to upload my files and see if anyone can spot something I've missed. Included in zip: dsdt.aml ssdt.aml org.chameleon.Boot.plist smbios.plist m17x-r2-speedstep.zip
