Sure i can
1. Installed the Nvidia Graphic Drivers from TonyMac86 but the updated ones cause of the new 10.6.6 update.
2. I Set my System Definitions with Multibeast to Mac Pro 3.1
3. Installed the NullCPUPowerManagement.kext (even if it means sleep is gone but at least now my Graphics run also my whole Mac seems more smoothy)
This is how my MultiBeast looked like after Installing the Graphic Drivers and Mac Update
After that i restarted my Mac and fired up Cinebench First to see if my Graphics do better and they did
I started up Sc2 and it finally let me pass the Login Screen !
I also have to mention i used the CustomBeast from TonyMac and not the normal Multibeast to set up my System first. So its a DSDT based system!
After i did some reading i set the PCI Express Frequency in my Bios to 100 MHZ also cause of the random crashes the Nvidia Drivers produce and know even these are gone
The other options i set in the bios were like described by lnx2 in that link i posted!!
I hope this helps you in any Way !
If u have any other questions Im happy to answer them!
Oh and here is my Extensions Folder so these are the Kext i have installed currently
