NB HT voltage.
Aaai. This thing. I love it and hate it at the same time.
Going off the sig.....
NB at 2.7ghz if stable, keep it that way. HT speeds at 3Ghz is ok. I've had mine past 4Ghz. At 4.2Ghz HT, the IMC had gotten damaged and will only run single channel memory. MacsBeach at Warp9 can confirm this.
Really the loss in stability comes from Cpu temps and too high NB frequency and Memory OCs.
At any rate my daily voltages for NB and HT where.
HT = 1.45v 3Ghz = 1.5+ between 3Ghz and 4Ghz.
Cpu/NB 1.35-1.45v depending on memory clocks. Higher clocks higher voltage.
NB (core) 1.3v (never exceeded this personally)
Cpu and memory vary too much this depends on your hardware really.

Ultimately, the best performance gains would be in 200Mhz cpu increments. If you ran a bucket of Ice water in a loop on that cpu, I bet you'd be around 5.4-5.6Ghz. And you'd be surprised how far you can go with just your current voltage used now at 4.95Ghz....
