Asus P8Z68V LX issues with EIST

[galli2000]

Hello,

Here is my conf.: Asus P8Z68V LX + Intel Core i5 2500K + RAM Patriot PC3-12800 1600MHz 8GB (2x4GB) + nVidia GT240 512MB GDDR5

I used to have a perfectly working system on 10.8.5, no DSDT, but since Mavericks update (Unibeast method), I cannot start with EIST enabled in the BIOS.
Still this infamous error when booting:

P-state stepper error 18 at step 2 in context 2 on CPU 0

then system stops.

Any idea?
Thanks

Hi,

In case this may be helpful to s.o else, I solved my problem by replacing Mac Pro 3,1 with iMac 13,1 in the System definitions of MultiBeast 6.
Now, EIST is enabled again in the BIOS, and Mavericks boots happily

Cheers
