3.2 kHash/s on GTX 780Ti
3.2 kHash/s? Is that a typo? Or perhaps that's the increase you're seeing now? Sorry, I'm confused.
scrypt-jane. that is a STELLAR value (considering the memory limitations of the card - it cannot run enough threads to fully occupy all the multiprocessors because each thread requires 4MB of RAM on the card).
With the Kepler kernel I was getting only 2.5 kHash/s at -l K7x3. By the way, my GTX 660Ti got 2.5 kHash/s too. High end cards have too many shaders and not enough RAM for scrypt-jane.
