i have an x2 3800
off the top of my head, i wanna say stock vcore is 1.32?
anyways, i have mine bumped up to 1.51-1.52
overclocked to 2.52, stock is 2.0
stock heatsink and fan, with 5 80mm fans throughout the case
in my basement with average room temp no more than 55-60F degrees.(im not a big fan of turning on the heater
i do not plan on using this processor for more than 2 1/2 years, so any impact on the lifespan of this processor does not bother me any.
