Here's the result when I use autotune...

[2014-02-27 15:57:33] GPU #3: cudaError 6 (the launch timed out and was terminat
ed) calling 'cudaDeviceSynchronize()' (D:/Christian/Documents/Visual Studio 2010
/Projects/CudaMiner/salsa_kernel.cu line 644)

"launch timed out" is unusual for autotuning an scrypt coin.

use -l T14x24 instead of -l T14x32. This should fit your cards.

the problem arose when you updated your cudaminer release from a December 2013 to a February 2014 release. Kernels were swapped out (nVidia's submission proved to be a bit faster than David Andersen's kernels).

T14x24 launches and hashes around 7-8 kh/s on each card for a few seconds...then I get the same launch error on GPU #3

Should I try to go back to the December version? Am I missing a prerequisite software to make this work with the latest version?
