At that voltage I presume you're overclocking? Make sure you're checking voltage properly, with the ground probe directly on the power plug of the PCB and the other probe on the VRM output. Next, I'd check the output of all the VRM's to see what they are. Most of my overclocked blades worked best when set to 1.185. Sometimes they could go lower but not usually.
If you aren't overclocking I'd suggest 1.045-1.07.
Make sure your cooling is adequate also. I'm using one fan per blade, each fan is at least 105cfm, some are 125. The fan is oriented beneath the blade blowing up across both sides of the blade. This keeps them pretty much cold to the touch.
As to the hashing, my effective hash rate for most OC'd blades is above that. I'm presuming cooling and voltage inconsistancies are causing you issues. Also, I would suggest BFG proxy if you aren't already using it.
Thanks for the response. I meter the board as per this video
http://youtu.be/M4PP9XnNKnA?t=2m24s. I do meter all VRMs. I have three fans on the blade. One on each side blowing across the PCB and a third larger fan blowing across the entire area. Yes, over-clocked.
I used to get between 10 and 11 GH/s with these settings consistently. This is running at my office, and this is what I found this morning. Two hard resets haven't changed it so far.
