As for LLC: I find 50% to be optimal from a thermal perspective. Full load voltages should be around the same (close) regardless of which LLC level you choose, while idle VID will need adjustment to ensure that the target VCC is adequate under full load. Technically, higher levels of LLC require a faster switching frequency and/or bulk capacitance to maintain overshoot and undershoot thresholds. While these are all accounted for in the levels we provide, I find myself sticking with a middle of the road approach as it is kinder to components.
Thanks, Raja -- that's very helpful. I'm using manual mode, as my 3570k needed only 1.24 Vcc @ 4.7ghz in that mode, whereas in offset the lowest I could get was 1.27 (at 0% LLC), while also keeping the idle Vcc stable. Apparently the VID curve was a little pessimistic for this particular chip.

That experience brought up another question/suggestion -- could a BIOS have 2 offset controls: 1 for Vidle, 1 for Vload, and interpolate in-between?

Thanks again,
David
