Ok so I tried the first one, deleted NCPM and installed LPC_injector.kext. It seems to be working, but only at 2 frequencies, 1.6 ghz and 2.4 ghz. Is that normal for this processor?

Audio did not work after removing VoodooHDA and HDADisabler, I manually loaded AppleHDA and nothing showed in System Profiler or System Prefs. I tried rebooting but I got a PWOD, after removing AppleHDA it was fine. I don't know if the audio is sigmatel or not. How do I tell? I googled the couldn't built-in audio but I'm not finding anything about what codec it is.

What is your CPU model? Have you enabled Generate P and C states in your Boot.plist?

The CPU is the c2q q6600. I have both c and p states enabled and I have c1e and speedstep enabled in bios.

My Q6600 (Kentsfield) is OC'd to 3.0 GHz and has four speedsteps of 1998, 2331, 2664 and 2997 MHz. When I use IOReg to check ACPI_SMC_PlatformPlugin, the RHS window shows that PerformanceStateArray contains 4 values.

My Q6600 is the G0 (SLACR) version.........the earlier Q6600 CPU version is the B3 (SL9UM).......http://ark.intel.com/products/29765

I have seen other Q6600 CPUs reported as having only 2 P states: 2400 and 1600 MHz..........perhaps they are the B3 revision?

For audio see http://www.dell.com/...Product/xps-720 and http://www.dell.com/...Product/xps-720
