CPU freq is 0MHz in HWMonitor (i7-3770S)

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!

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

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

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