Regarding the lack of CPU PLL VOLTAGE regulation on the Z77E-ITX - I FINALLY got an answer after bumping my post at their support-forum (And sending them 2 unanswered support-tickets) for a full month. Not exactly the CS I was hoping for when choosing Asrock ....
Anyhow, the official response from Asrock, ASRock TSD - Emily:Dear all,
Z77E-ITX doesn't have CPU PLL voltage option.
Please kindly refer to below link to check Z77E-ITX user manual.
There is no the option in user manual.
If you would like to have better performance on overclocking, you could choose our Z77 Extreme4, Z77 Extreme9 etc...
These models have the option under BIOS.
Have a nice day
So there you have it, no CPU PLL voltage options on the Z77E-ITX.
Will be moving the motherboard over in my HTPC/Media-pc and go with another brand. To bad, I really liked the layout and post-speed on the little devil
