[Success] MSI G77A-G43 Mountain Lion Build

[sixsixtysix]

I didn't enable it with a SSDT, but I have tested it and it is working with the modified Bios. It clocks between 3.4 and 4.6Ghz and so far so good, no crashes and the CPU never gets above 60c even at full speed for extended periods of time.

Just a quick update. After further testing, I have made a few tweaks to this build.

First, the built in 8111e Ethernet on this board is junk. It works great 95% of the time, but if you are using it for heavy file transfers like remote Time Machine backups on a gigabit network where speeds are getting up to 60-70MB/sec, the connection drops and requires a restart to get it back. I ended up buying a cheapo Trendnet PCI NIC for $12 that works with the Realtek 81XX driver, although you still must keep the onboard NIC enabled in the Bios or else the App Store won't let you download.

Second, after a couple weeks of beating on the machine, I realized that I was only getting 2 SpeedStep states, 16 and 46 so I made a custom SSDT.aml with 31 steps between 16 and 46 which is for my 4.6GHz over clock. I also had to change the SMBIOS profile to MacMini 5,1 since I found out that the iMac 12,1 and MacPro 5,1 only support 2 SpeedStep states, now MSRDumper is reporting all the steps working correctly.

I have attached the custom 4.6Ghz OC SSDT.aml for a i5 3570K if anyone else has their system running at this speed. Even if not, the steps are easy enough to modify for your own use.

Here is the DSDT I am running. (Sorry, I had to zip it because it was over the 29K file limit for aml files.)

Thanks, I have had the 6870 running fine, it was just the ports that were confusing me since you can't run both DVI ports.

Great built; interested in 892 audio. At your convenience, reply with an IOReg with Internal Speakers selected and iTunes playing. [Guide] How to Make a Copy of IOReg. Thanks.
