It all boils down to cooling, 1.4V is stock voltage for most of AMD's 0.09 micron processors. Heck my Opty 148 did 3.1 GHz on 1.4V so that should tell you that cooling is the most important thing when it comes to overclockign with stock voltage.

so in other words, if you can't get your proc cold enough, then you need to jack up the voltage?

Yes if you believe the processor is the bottleneck, increasing the voltage will increase the signal strength between transistors (as well as produce more heat).

The Optys 939s seem a bit less power hungry

Im running my 3500+ at 2.5Ghz with 1.625 volts. hardly ever gets above 45C.
