I am hoping someone will find fault on my rig setup and be the answer to getting the card up to spec...
 
Corsair HX750M PS + Corsair H110i cooler + 1-coolermaster 240MM fan cooling the board + good exhaust for the radiator (this same exhaust keeps a small room /w 4 S1's @~72F)

-I used the procedure in the Prospector card thread to attach the cooler using the 8/32 nuts.
-Cleaned and re-applied thermal paste on the board and cooler.
-The PS has all 4 Pci-e plugs attached
-I tested the OC from 400MHz-850Mhz and found the board hashed no faster and only created more heat for no gain... I let the board run for ~1 hour for testing at different OC levels.
-Getting <600GH/s steady @775MHz @~87C @.83-.85V (per cgminer 4.3.3)

I am beginning to think this is a card problem... Anyone else have a different outcome?

  
EDIT: The "masking tape" test results sent with the card show 686GH/s @ .88V @800MHz. I can get nowhere close to this number.
EDIT1: PIC!
