[Success] ASRock Z68 Extreme3 Gen3 - i7-2600K - XFX Double-D HD 6870

Everything I have tried seems to work. Except waking from sleep can take up to a minute and a half.

Files I used:

Multi-beast 5.0.2
KextBeast
ShowAllFiles
UniBeast - Mountain Lion 1.5.3

Patched AppleIntelCPUPowerManagement.kext for 10.8

Mountain Lion 6XXX GPU Issues - FIX INSIDE!
http://www.tonymacx86.com/mountain-...mountain-lion-6xxx-gpu-issues-fix-inside.html

First I downloaded UniBeast 1.5.3 and created a Mountain Lion install flash drive.

Then prepare the flash drive for my 6870 video card installation by backing up the ATI6000Controller.kext file by copying it to the root of the USB drive and then deleting it from the System/Library/Extension folder like the 6XXX GPU FIX article says. I used ShowAllFiles download instead of the terminal command listed on line 2.

I then boot my Unibeast flash drive and tell it to boot from the USB stick using only the -v command so I can see what is happening. It boots to the installation screen and gets to the desktop without issue in low rez mode and I have internet access. Then I go to software update and install 10.8.1 and reboot using unibeast and -v command on my SSD.

It gets back to the desktop and I go to Finder and select my computer. I drag the ShowAllFiles command from USB to desktop and right-click on it and select Open (otherwise I get a no permission error when double clciking) and give it permission to run. then I click SHOW to show hidden files and folders. I go back to the USB folder and copy kextbeast and the ATI6000Controller.kext to the desktop and again right-click the kextbeast commcand and select run and it will install the kext for the video card. you do not need to reboot and can continue to mu;tibeast setup.

Then copy multibeast 5.0.2 to the desktop and right-click and run Multibeast 5.0.2 Then just select the

"UserDSDT or DSDT-Free Installation"
Drivers and Bootloaders -->Drivers-->Audio-->Without DSDT-->ALC892 (always use without DSDT even if you have a DSDT)
Drivers and bootloaders --> Drivers ---> Network --> Realtek Gigabit Ethernet 2.0.6 for 10.7 (Lnx2Mac will work also)
Drivers and Bootloaders --> Drivers --> Disk --> IOAHCIBlockStorageInjector (so drives aren't marked as external)
Drivers and Bootloaders --> Drivers --> Disk --> Trim Enabler (for SSD)
and that's it. click continue and it will create a bootable disk with sound and networking.

DO NOT REBOOT!!!

Now you need to go through the AppleIntelCPUPowerManagement article and navigate to your ssd/hdd where you installed Mountain Lion and go to the folder System/Library/Extension and delete the AppleIntelCPUPowerManagement.kext file and copy the one from the article you downloaded and copy it to your desktop and run kextbeast so it will reinstall it. Make sure you ATI6000Controller.kext you copied to your desktop is deleted so it doesn't run again.

I still have a random optical drive polling issues. Not sure what's causing it yet. Other than that it seems fine.

Awesome thanks for the write up man!

Do you mind posting your DSDT? I have searched far and wide for a correct Extreme3 Gen3 DSDT for my build but have found nothing...

I have created a generic DSDT for BIOS P2.20 in this thread:
http://www.tonymacx86.com/dsdt/69984-help-me-make-dsdt-asrock-z68-extreme3-gen3.html#post434410

I found I didn't really need it though. I had to install with the same procedure with or without the DSDT.

Luck

I had to add the i7 SSDT for speedstep to work otherwise, it would stick at idle (1.6GHz)

Installed from Multibeast 5.0.2:

Customization --> SSDT Options --> Sandy Bridge Core i7

Awesome, thanks I'll check that out. Did you ever get sleep/wake to work? I never could..

EDIT: Nevermind, I just re-read your post about it taking up to a minute and a half. Thanks mate, I'll look into and let ya know.

Dude I am so totally stoked right now That DSDT got sleep/wake to working on my hack! Now everything is 100%

That had been bothering for about 6 months lol, I truly appreciate it man!

Have a good one
