Now, put the settings back to stock (clock 550), cgminer will show 420 GH/s but the real hashrate will be <395 GH/s. Not even the 400 GH/s we were promised.
UPDATE: Switched around pools I'm getting different results, some better. So maybe it's a little over 400 gh/s. Definitely 423 watts, tho...

Yep. This seems to be the case here. I'm apparently hashing about 395 gh/s and pulling 423 watts at the wall. It seems to be under spec. Not hugely, but significantly.
(cgminer 3.11 default settings)
Piping some very cold-ass air into it from outside, maybe 50f/9c, I can get the processor temp down to mid-60s and the hashrate apparently rises to a little bit over 400, but I can't leave the window open forever!
