Should CPU stability at a certain vcore be the vcore in BIOS or after vdroop?

I'm currently running my Q6600 at 400x9. BIOS vcore is currently set at 1.5V, but real world vcore after vdroop is ~1.4V. I haven't gotten around to actually finding the lowest stable vcore yet, so if this seems high, it probably is.

1. So should stability at a certain vcore be stated as a BIOS setting or as the actual vcore after vdroop? I think the latter because different motherboards have different amounts of vdroop, so a mobo that doesn't droop as much may seem to be able to run the same CPU at the same clock speed at a lower vcore than a mobo that droops more.

2. Also, the CPU is rated to a maximum of 1.5V. Since my mobo's vdroop seems to be -0.1V, does this mean I can safely set 1.6V as the vcore in my BIOS while trying to get a higher overclock?

The heavier the CPU load, the more power it draws, and the more the voltage droops, so it's best to report the set voltage (the voltage specified in the BIOS), rather than the reported voltage.
Intel says 1.55V is the absolute maximum voltage for the Q6600 and that higher voltages will almost certainly damage the CPU, so I wouldn't set a voltage higher than that.
