So im best to ignore the high hash rate benchmarks?
For now I have a random value set because of auto tune messing up so badly.
I tried T11x13 on my 780. This is said to give 880. Gives around 440, yet I am able to get 503 from another config but I can not figure out which to use as the benchmark values are so off
I guess you have overclocks. Autotune doesn't seem to like that.
Anyway, cudaminer by default uses scrypt, that's what you're using, scrypt-jane is something else.
I just mined my first Yacoin block SOLO. One 660Ti plus 2 GT 640 cards add up to 4.5 kHash/s, which is significant hashing power for Yacoin (the whole Yacoin network is around 1000-1500 kHash/s only, with blocks being generated once per minute.)
Some scrypt-jane hashrates for comparison:
i5 3570k - 0.41 kH/s
i7-3930K - 1.20 kH/s
FX-8350 - 0.57 kH/s
5770 - 1.0 kH/s
7950 - 1.3-1.5 kH/s
R7 250 - 1.44 kH/s
