I got my system up and running on mavericks quite well with clover boot loader. But i must say I'm a bit confused by the power management:
When I take a look into the Intel Power Gadget, my system seems to speedstep nicely between 0.8 and 3.3 ghz on the CPU, and also GPU stepping seems to work fine. But when I run MSRDumper, It seems to me that only the lowest + 2 turbo boost states should actually work:
23.02.14 09:03:46,000 kernel: MSRDumper PStatesReached: 8 31 32 33
At the moment my system runs a patched Kernel bc I was experiencing kernel panics (I know my GA board should not lock the register, but Iit seems to run fine now), Clover is on vanilla config.plist (only with DumpOEM=true and SSDT for HDMI audio) – so GeneratePStates and GenerateCStates are both on. And of course native AppleIntelCPUPowerManagement.kext.
I tried a generated SSDT for Power Management but that ended in the same result.
So can I trust MSRDumper or the Intel Utility? Or does the CPU even step via front side bus when it detects the missing ability to change multiplicators? Would seem strange to me though.
Ideas very much appreciated!
