ivy bridge only 1 core

[gerryonetwothree]

Hi!

My problem is, that on my i7 3770 ivy bridge processor, there´s just a single core recognized by Geekbench and also by MenuMeters.
I am running ML right now, but problem also occured when i was still running Lion. With just this one core i just get scores at about 5k in Geekbench.

Motherboard: ASUS P8Z77-V LE
CPU: Intel Core i7-3770 CPU @ 3.40GHz

Help would be really much appreciated.

You may need to install the "Core i7" SSDT kext from Multibeast.

It's under Customization > Boot Options > SSDT

Install the Core i7 option and restart.

already tried that, but ssdt isnt needed with ivy bridge (Point 11 -> tonymacx86 Forum • View topic - Lion Installation Guide for Ivy Bridge CPUs [UPDATED])
i really don´t know what the cause could be...
