Yes the nVidia submitted kernel is expected to run 10-20% faster than Dave Andersen's kernels.
*sigh* I was almost hoping that was not the case. Now In good consonance I can't leave it be and only hash @ 500 kh/s a card.
Back to fucking this some more.
500 is fairly good on a Titan without overclocking. I've got my solo titan at 620 with +155 Core -502 Mem, try it.
Is that using the latest cudaminer? What kernal settings are you using?
Yes, latest version cudaminer, tried both x64 and x86 versions, same within a few khash of each other.
Settings are: -m0 -l T5x24 -i 0 -H 1 currently, although I have tried different values and none seem to make much, if any, difference.
