Hi,

HWMonitor shows 0MHz for CPU frequency which is strange.

There are also some errors in dmesg probadly related to it.

IntelCPUMonitor: CPU family 0x6, model 0x3a, stepping 0x9, cores 4, threads 8
IntelCPUMonitor: Using efi
IntelCPUMonitor: BusClock=100MHz FSB=401MHz
IntelCPUMonitor: Platform string T9
IntelCPUMonitor: CPU0 Tjmax 103
IntelCPUMonitor: CPU1 Tjmax 103
IntelCPUMonitor: CPU2 Tjmax 103
IntelCPUMonitor: CPU3 Tjmax 103
...
ACPI_SMC_PlatformPlugin::start - waitForService(resourceMatching(AppleIntelCPUPowerManagement) timed out
WARNING: IOPlatformPluginUtil : getCPUIDInfo: this is an unknown CPU model 0x3a
-- power management may be incomplete or unsupported

Any idea?

Thanks for help!

Does incorrect CPU identification result in power management problems?

Hi, I am having a lot of problems with Mountain Lion installation, one being 'resume from sleep'.
I have worked around this by System Preferences-Energy Saver-Computer Sleep, Never
My CPU is Intel 3770K.
I read that SandyBridge had a problem and SSDTs had to be replaced.
Is this the case for IvyBridge?

BTW Should I be using MultiBeast 4.6.1 - Lion, or is there a Mountain Lion edition?
Could this be the cause of all my probalems , mainly slow loading of OSX and Keyboard/Mouse not working for 4+ minutes?

Many thanks

Hi,

I managed to get frequency show up by installing new IntelCPUMonitor.kext


It's the same for all Ivy Bridge CPUs, so it's not unique to your chip.

@thelostswede : Do you have also these errors in dmesg?

ACPI_SMC_PlatformPlugin::start - waitForService(resourceMatching(AppleIntelCPUPower Management) timed out
