Vdroop and power phase question

[Video_freak]

Hi everyone, I just got an i7 a week or so ago and started doing some overclocking recently. I managed to stabilize 4.2 GHz at 200 base and 21x multiplier (on a 950) at 1.3v flat. The only problem was when I disabled load line calibration and xtreme phase full power mode on my P6X58D-E. I left the voltage at 1.3v, but now vdroop is making it so that the CPU gets 1.26-1.27v idling and 1.24v under load, which makes it fail OCCT within seconds. Should I bump up the voltage to compensate, or just say screw it to Intel spec and enable the vdroop control?

Also, my QPI is set at 1.275v right now. I originally tested it at 200 MHz and 1.25v, which worked fine because the RAM and CPU were separated (underclocked), but I ran into stability issues and gave it 1.275v to make sure everything would run well. Should I bother lowering that voltage closer to 1.25v, or should I not?

Thanks

why would you disable the load line calibration? That doesn't help overclocking afaik

Screw intel spec, enable llc. I'd keep qpi at 1.275, not much of a difference and it really does make a difference (in terms of stability, if that makes sense).

Alright, so the voltage spikes aren't that dangerous after all then?

Oh also one last question; I set my northbridge (or what's left of it in the i7 architecture anyway) to 1.3v (1.1v stock) when I started overclocking. Should I bother trying to lower that? I've seen some people using around 1.2v with success at similar overclocks.

I disabled it after getting a stable OC because I would ideally like it off for 24/7 use because I thought voltage spikes were dangerous.
