Okay, Does anyone know how to edit the Bios properly to keep speedstepping. Because if i go in, and change anything with my ram, depending what is changed, i lose speedstepping. And other times i lose turbo. It sucks! And i can't figure it out. Like X.M.P. makes me lose speedstepping, but if i change one of the options back to auto (something to do about cores), speed stepping works, but turbo doesn't work. Like what the hell.
There's a bug in the ASUS bios where if you manually set the turbo states, it causes you to lose a couple p-states (usually the ones between 16 and 34). When set to auto you should get them. I also did notice that when i set my system to XMP, it messed a lot of things up (lost p-states, random KP). What i did was to not use XMP and set my RAM to the settings i wanted manually (DDR3-1600, 9-9-9-24, etc).

Thanks for checking my SSDT and DSDT. With an unmodified AICPM and SMProductname = iMac12, 2 in my SMBIOS, I have only the p-states 16 and 34 and my USB ports do not work and I have IOUSBDevice errors, ( attached images in my last post ), when I start the system, ( this error appears even with a patched AICPM ) . This iMac12.2 plist I spoke, (which I think contains the StepDataDict from MacBook 8.3), it's inside the Plugins folder of IOPlatformPluginFamily.kext ... I don't know what else to try ...
I'm at a loss too. Since you say it worked properly under Lion maybe they changed something else in the code. We may just have to wait until ML gets close to final release and people smarter than us figure it out.
