Look on forum similar configurations (GA-Z77-DS3H or GA-H77-DS3H, only the Intel chipset differ, the Z one allow OC) to see what to choose on Multibeast. Update your bios (you need Windows or Cross-over (for Mac) to extract the bios file, then put it on a FAT32 drive, you can use your phone), old bios versions can cause many kernel panics, I experienced it myself on my GA-Z77-DS3H. Your Intel Graphics Chipset is not supported by OS X, so you need a graphic card to have QE/CI working. Then, you have to install bootloader: Chimera (available in Download section of this website) or Chameleon to boot without USB.
Personally, I used Multibeast only to install VoodooHD audio on 10.8.3 update, I used an all-in-one package for GA-Z77-DS3H (compatible with H77 chipsets).
Some links for you:
Configuring UEFI
A build using almost the same motherboard as you
All-in-one GA-Z77-DS3H package (need to install a patched AppleHDA or VoodooHD audio from Multibeast after)
UEFI/BIOS update Check your rev before updating, there is different files for each rev!!! (rev 1.0 or rev 1.1) (written on the motherboard)
