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

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

  



Having the same issue's as you, same PSU, running the H80I cooler, extra fan blowing across the board.
Followed the Prospector card procedure to attach everything and I can only average 600ghs @ 800mhz @ 91c-93c.
Anyone have an idea on how to get over 700ghs?
Masking tape test results on ours showed 689ghs @.88volts and 800mhz...can't get anywhere close to that number,
even running an ice chilled water cooling system @ 800mhz still only pulls 600ghs average @ 90c.


What base are you using with the water block? I used the block of aluminum that came with the OGR card. The base that came with the H110i has threaded standoffs that were too long going through the board and would never work.
