What list said you should stay on BIOS 1.20?
Given the parts you listed for your PC, I see no reason for IME not installing. What version did you try to install, and where did you get it?
Intel Dynamic is an older feature used on some older mobile CPUs, and has nothing to do with a Z77 Ex 6 and an i7-3770. Your CPU uses Turbo 2.0, but there are no files associated with Turbo boost. What are you talking about?
