[Success] MSI H77MA-G43, Intel Core i5-3550, EVGA Superclocked Geforce GTX 660 Ti

Finally got everything working after multiple attempts (read: reinstalling ML at least half a dozen times) and desperately searching through forums for a few days. Here are my hardware specs:

- MSI H77MA-G43
- Intel Core i5-3550
- EVGA Superclocked Geforce GTX 660 Ti 2gb
- Samsung 830 256gb SSD
- 16gb Corsair Vengeance DDR3 1600 RAM
- TP-LINK TL-WDN4800 Wireless N Dual Band Adapter
- Corsair TX650 V2 650W PSU
- Silverstone Temjin TJ08B-E MicroATX Case

Pre-installation:

- Flash the H77MA-G43 BIOS with the patched BIOS from samisnake (http://www.tonymacx86.com/dsdt/47397-msi-asrock-foxconn-1155-patched-bios-thread-27.html#post375926)
- Disable VT-d (Intel® Virtualization Technology for Directed I/O) for the CPU in BIOS otherwise UniBeast nor Mountain Lion will boot without the -x safe boot flag

Installation:

- Follow the UniBeast guide to create a bootable Mountain Lion installation USB drive
- Boot from the USB drive with the PCIRootUID=0 and GraphicsEnabler=No boot arguments
- Format/partition the main hard drive as desired and install Mountain Lion

Post-Installation:

- After the initial installation boot into Mountain Lion, still using the PCIRootUID=0 and GraphicsEnabler=No boot arguments
- Install MultiBeast with the following options selected:- After rebooting post-MultiBeast installation, install the latest nVidia graphics drivers and CUDA drivers (may not actually be necessary)
- Fix sleep/wake/freeze issues
Everything else seems to be working great so far. The only strange things that I've noticed, and have yet to figure out, are:

- After waking from sleep my HWMonitor temperatures for the CPU Heatsink and Northbridge seem to double from where they were prior to going to sleep. We're talking like over 200 degrees Fahrenheit here, which can't be right...
- USB 3.0 ports aren't backwards compatible with USB 2.0 devices. They work great with USB 3.0 devices though. Not sure how to fix this yet.

I hope this write-up of my experience will be helpful for someone, just like how the rest of this forum was instrumental in helping me get my first hack ever up and running.

Hey glad you found success I have my setup diffrent but we have the same video card. I'm new to this stuff and i'm not sure how to even start it up with the video card attached.

//- Boot from the USB drive with the PCIRootUID=0 and GraphicsEnabler=No boot arguments//

In that step how do you get both to run? like how do you put 2 commands?

after PCIRootUID=0 i hit ENTER and it starts up. How do I get a second command in?

In the most un-sarcastic way possible. Space bar, then type the next command.

lol, I didn't have a clue. Thanks

BUt sadly I still get a damn kernal panic before I can even reach the OSX installer

Copied from another thread on the H77MA-G43, pasted here for future reference. So far this seems like the best guide here for this motherboard.

"Hi! I have the same mobo, does your USB 3 ports work? I have some troubles with native USB 3.0 support P.S.Solved with xHCI Mode - Enabled in BIOS."

Same mobo here, and I haven't been able to get anywhere. I had 10.6.8 running great.

Does the ability to turn off VT hinge on the BIOS flash? It took me a minute to find it in the overclocking section, but I can't change it.

I am wary of flashing my BIOS, I just trashed a HP laptop when I flashed it with their updated BIOS.

Kind of off topic, but could anyone with an EVGA 660 ti SC 2GB card upload their BIOS with TechPowerUp's GPU-Z in Windows like this http://i.imgur.com/xu6AZEu.png I have been hunting for one with absolutely no luck whatsoever. I would be eternally grateful.

I have the Z77A-G43 which I believe is somewhat related, and I can't disable VT-D in the bios either (I can see in the manual it used to be possible to disable it (OC Settings->CPU features) but that submenu is gone from the bios). My machine boots without the -x flag (though I did have to use -x for the install).

Thanks for the thread & info, I am working on this motherboard for my son over the next few days.

***Update 9/10/2013***
This is almost all working, the BIOS is patched to 1.9, and I am using Mavericks.

Had to install:
-v -x PCIRootUID=0 GraphicsEnabler=No USBBusFix=Yes

It boots up now and shuts down fine, but if it goes into power save mode it does not want to come out of it with the ps/2 keyboard or USB mouse. Going to try your other listed fix for the power management next.

I still kept in the boot up control file: PCIRootUID=0 GraphicsEnabler=No USBBusFix=Yes

Where did you find the copy of the 1.9 patched?
