My current specs are almost identical to this build with the exception of the processor being a i5-3570K
I'm having difficulty getting Ivy Bridge Power Management working properly having done everything in this tutorial to a T. Maybe I'm missing something though.
On boot I get the following which I find strange..
Jul 7 20:21:13 MacB0x kernel[0]: X86PlatformPlugin::setRingTable - AICPM failed to load ring table with status 0x0: Get=0, Load=0, Install=0

and also when I check to see if Speed Stepping is occurring it only gives like two P-States?
one command of cat /var/log/system.log | grep "AICPUPMI:"
outputs:
Jul 7 22:21:20 localhost kernel[0]: AICPUPMI: CPU P-States [ 16 34 ]
Any help would be greatly appreciated, Thanks
