I just finished a new build with the Z68XP UD5 & 10.7.3 this week. I tried the f4 and f5 bios & DSDT combos and f4 gave me much faster cinebench results! However, I cannot get the machine to reboot or shutdown properly
Windows shuts down and restarts properly but when OS X shuts down, the computer never turns all the way off. I tried the EvOreboot but it doesn't seem to be working.
I used the Unibeast/Dual Boot (w/Windows 7)/Multibeast method with f4 DSDT. Everything works smooth (sleep works) except for shutdown and restart. Even got my GTX 570 fully working without a whole lot of effort.
Interested to know which bios and DSDT combo you use...
