Sorry still half a sleep that would be Ghash. The site only shows it as 6600Mhash/s as of right now so I'm guessing that would be 6.6 Ghash.
Also I'm running them all on bfgminer and not over clocked. I will check what it says they are at when I get home. They seem to bounce around 1.5 and 1.7. The lowest I have seen is 1.4 and the highest was 2.
For weeks i get 1.97-2.02 per U1, stable

Easy to OC.
but not too easy to go upper than 2 without a particular cooling system so far i have seen.
