hardware is a good friend of mine
have you an unlocked firmware for your MSI mb? Which OSX version are you trying?
if not, you have to patch with sudo command found in first omni post your AICPUPM kext
Then you have to use another patch to let see your 3930x to OSX (file 03 to download from omni's link )
Then you can generate your ssdt with PikerAlpha script and you should see all pstates with AICPUPMI kext (latest release)
set up Maverick 10.9.3
everything works except the speedstep
for as if firmwae is blocked
