Is this when you trying to run just 1 card or several at the same time? When I run 4 simultaneously I can only get about 1.5mh/s per card. With the same OC I get 1.65mh/s to 1.7mh/s with only 1 card active.
I am only running 1 card. I only have a single card now. What OC setting u use ? i saw someone on earlier post (using same model) getting 1.75 mh each running 5 cards. What is your GPU load ?
I've got 1310Mhz on the core and zero overclock on the memory. These are two fan Gigabyte 750Ti cards and with all 4 cards active they are at 80% load each according to GPUz.
