I have GA-Z77-DS3H with i5 as well... but I can't install ML... I ran the new UniBeast, than BridgeHelper, reboot and booted USB Drive... Kernal Panic... Not to sure what is going, but hopefully I can figure it out and be up and running soon... Lion Geek Bench was just shy of 11K
You must not install BridgeHelper with ML.
I didnt. I installed ML successfully. I was able to reboot once, then once I installed MultiBeast, it started panicking.
