safe p4 voltage

[vekk]

Hey I've currently got a 3.0c running stable at 3.455ghz at stock voltage. I should be getting an xp-120 pretty soon and I am gonna go for a high overclock. I was just curious as to what the highest voltage I could push this to on air and not worry about SNDS.
thanks

many people say to keep it under 1.7, me personally i wouldnt want to run a p4 system 24x7 at anything above 1.65v
