80KH/s is what you get with OpenCL. NeoScrypt CCminer can do over 200KH/s for the 750 Ti. Follow the links in the OP.
Yes, I was using the version for amd cards, my mistake.
With the ccminer version I get 150 Khs without any OC.
With OC I get 180 Khs.
With the official CCminer from github for Windows i got 190 khs.
Maybe it is needed to install the same CUDA version the miner is built with.
Not that it matters anyway, with a 750ti you're mining pennies, I just want to see what it can do.
Thanks ghostlander.
