Guys having some issues with the CPU Voltage.

I have my Q6600 at 3.3ghz with everything on auto apart from CPU Volts and ram volts.

RAM is at 2.2v as thats what it said it should run at, no problem..

CPU tho is another matter I had it set to 1.40v or so in bios and yet in CPUZ it was showing at around 1.3v so went back in to bios to check the setting sure enought 1.40ish, upped it to 1.5v and in CPUZ and sisofts sandra it shows up as 1.4v? is this a known issue? was wondering why I kept getting BSOD when running 3Dmark 06 and vantage at 3.3ghz with a 1.4v as it was in fact running it at 1.3v?

Any ideas?
