Used latest chameleon, auto-patched dsdt, combo-updated 10.6.3 to 10.6.8 by removing ACPI_SMC_PlatformPlugin.kext from IOPlatformPluginFamily.kext prior updating to avoid KP during update.

 

What can cause such low geekbench scores? :blink:

LOL, a badass motherboard indeed)))

 

However, low geekbench score usually indicates that something is wrong. And the computer feels like an old Core2Duo...

 

Installed NullCPU and geekbench score increased from 4512 to 8947!

Does it means something is wrong with native power managment? But what can it be?

Might be an erratic SpeedStep behavior is to blame? C/P states namely. I'd check two things:

  • C/P states (via Chameleon or ACPI tables)
  • DSDT

On my notebook with CPU same as in first gen. MacBook (T2500), native power management works 100% perfectly (I've added some additional Methods from MacBook's DSDT CPU section, not sure if it makes any difference though :P ).
