Best I have gotten so far is 2.7ghz (245x11) @ 1.45V (would 1.5V be safe?). Anything over that it won't boot all the way to windows. I run a 9:10 mem divider on my ram to make this work. Not sure what I could do to push this a bit further. 
any other results? Interested to see if anyone got it over 2.8.
