OK, the voltage is automatically set by my motherboard, so I don't think I 
could touch it even if I wanted to. From what I've read so far, it's possible 
that these processors will run stably at this speed, it's just not a 
guarantee, so they've been rated very conservatively. I'll keep watching for 
signs to the contrary.
