Well i've been referring to scrypt mining i.e LTC - So if you got 700Mh/s SHA-256, you should get 700Kh/s scrypt, if you get what i mean.
What are you current settings for GPU/Memory clocks and voltages (the stocks if that's what your using) and cgminer settings for each card?
OK, I understand now. I've never dabbled in scrypt/LTC.
Catalyst Control Center → GPU: 1000, RAM: 1425, auto fan
The only command I use in cgminer is -I 9
