I'm only running 3x 7970 gigabyte hd edition and they crank out 2.3-2.5 mh/s. I can post my config for you if you want OP.
Please do.

What part of "every card is different" don't you understand? Just because someone gets 1200mhz on their card doesn't mean yours will. You could have good or bad asic quality. You could have really good power circuitry (such as pure reference cards) or really meh power circuitry, which also influences clock speed capabilities. Power quality from your PSU is also a factor; Having low ripple and incoming voltage at 12v (or very slightly higher) is optimum.
I find that "reference but not reference" cards, meaning cards with reference cooler but different color PCB and no AMD logo by the PCI-E connector, clock significantly lower than pure reference, something like 100-150MHz at the same voltage as a pure reference. Speaking from experience with 14 7970's.

Every card is different if you want to read asic quality read it with the program gpu-z. If your 60%-70% which I would guess you probably are you won't get 700 megahash. Sorry to ruin it for you. IIRC correctly you need 75-80% to hit over 700 megahash reliably

I got on my sapphire refernce card 65% asic quality and it still gets 700MH/s. By default it uses 1.175V, need to get 1.181 to be stable at 1174 MHz on core. Memory -160Mhz and it's mining happy.
