GUIDE: Gigabyte GA-Z77-DS3H + EVGA GTX 650 2Gb

After a bumpy start this 10.8.3 install went smoothly. The main issue was related to the BIOS with VT-d needing to be disabled which was not documented in the other GA-Z77-DS3H posts, this was identified using the switch -v on boot and reading a few forum posts.

Network, audio, DVI, VGA and both DVI ports on the GPU working. The machine is very fast booting up.

Hardware

Step 1 - Configure the motherboards BIOS (F9)

1. Connect your monitor to the motherboards DVI port.
2. Turn on the machine and use the Delete key to enter the BIOS.
3. Load Optimized Defaults.

MIT / Extreme Memory Profile (X.M.P.) = Profile1
BIOS Features / Intel Virtualization Technology = Disabled
BIOS Features / VT-d = Disabled

2. Hit F12 to select the boot device.
3. Select your USB drive (UniBeast).
4. At the UniBeast page type the -x boot flag.
5. Use Disk Utility to prepare your drive.
6. Install the OS.
7. Click Restart or wait for the computer to automatically reboot.

Note: the screen may go to sleep during the OS install process and will display the mouse pointer on a white screen. To get back to the install screen just hit the space bar.

Step 3

1. Hit F12 to select the boot device.
2. Select your boot drive and type the -x boot flag.
3. Set up your OS (you can skip most of the screens).
4. Sign-in using your password.
4. Download MultiBeast (your Ethernet port should be working).
5. Run MultiBeast.

Note: you may have to allow the MultiBeast application to run by changing the settings in the Security & Privacy control panel found in the System Preferences.

5. Select

MultiBeast / UserDSDT or DSDT -Free
MultiBeast / Drivers & Bootloaders / Drivers / Audio / Realtek ALC8xx / Without DSDT / ALC887/888b / v100302 Current
MultiBeast / Drivers & Bootloaders / Drivers / Network / Atheros - Shailua's ALXEthernet

Important: don't select everything at once, go very slowly.
Note: you do not need a DSDT with the GA-Z77-DS3H motherboard.

4. Click Continue to install.
5. Authenticate.
6. Quit MultiBeast.
7. Shut Down.
8. Remove the USB key (UniBeast).

Step 4

1. Turn on the computer and boot into Mac OS X.
2. Edit org.chemeleon.Boot.plist or run MultiBeast to change GraphicsEnabler = No.

MultiBeast / Customization / Boot Options / GraphicsEnabler = No

3. Click Continue to install.
4. Authenticate.
5. Quit MultiBeast.
6. Shut Down.
7. Install your GPU (GTX 650).
8. Turn on the computer and boot into Mac OS X.
9. Done!

Lastly I changed the mapping for the Logitech K120 keyboard:

1. Open System Preferences and select the ‘Keyboard’ preference pane.
2. Click the Modifier Keys button and switch the mapping. When you’re done, click OK and close the preference pane.

See attached image for the Modifier Keys settings.

Do you have any problems with sleep?
I have the same motherboard and a 660 GTX and it goes to sleep just fine but the screens do not come back on after.

Hi skunkworker,

Just double checked and yes its fine coming out of sleep.

Thanks for the guide!

I was looking for this motherboard in order to get a compatible motherboard with the sleep option.

Just to confirm:
- sleep works fine, the computer "shutdown" as when Windows is installed (led blinks, all fan are off, etc)
- the GPU is detected fine after installation? 3D games work fine, i.e. steam
- sound works fine too?


Regards,
Oliver

Click to expand...

is that off the hardware button or under the apple menu?
Strange, my machine comes back on but the monitors stay in standby mode.

Excellent guide!
Can you update with the GA-Z77-DS3H motherboard revision [1.0 or 1.1], as well as the BIOS & CPU versions?
Thanks!

Did you find a fix for the wake issue? I have the same problem. Everything else works great.

Thank you, great guide!

I have one question - did you hve HD4000 graphics on your CPU? If so, why did you need to have a GraphicsEnabler=no?

Hi Frenchman,
Does the USB 3 on this board works without problem?
