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.
