Check Intel's technical data sheet for the SNB-E, it will have listed in that the max and min safe voltage levels for every aspect of the system. It will also state the max safe temperature in reguards to voltage and its decline. Far easier for you to download this document and read that.

I would imagin the pll and vtt would be very simular to sandybridge.

Yea its all in there less than a scroll or two down, i took my info from their datasheets. Stay under 1.35v for VTT for 24/7 but please understand that VTT isn't as important as VCCSA, system agent is much more important for memory OC.

PLL voltage actually shoudl be raised for stability, it wont give you more MHz, but it will stabilize high frequency overclocks. The max on this has been lifted from 1.89 to around 2.0v, stay under 1.99v.

VCCSA(System Agent or IMC) and VCCIO(VTT) shoudl be taken up equally.

For best stability when OCing high speed ram at or around 2133mhz and above, please keep VCCSA and VCC(Vcore) at .3-.4v apart from each other, the closer they are the more stable the OC>

Have fun. If you need help you can always PM me or better post in that thread so others can learn from it too.
