I have on GTX TITAN with UTC mining all results with (booooo)! All parameters tried... bad build??
example: -a scrypt-jane:UTC -o stratum+tcp://pickaxe.pool.pm:3304 -d 0 -i 0 -H 2 -C 1 -m 1 -l Y6x32 -s 3
I'm using cudaminer 2014-01-20 (beta) downloaded on this forum from the last url (
http://rghost.ru/52135455 
I got it working yesterday after downloading the sources from Git and compiling them (on Ubuntu 12.04). Ultracoin info wasn't in the code until yesterday (
https://github.com/cbuchner1/CudaMiner/commit/ec3f4d3acbcb70b17049a1d9d8d4dc3b936c220d), so a version that's 12 days old will probably mine with incorrect settings.
I also had some trouble with the launch-config, 70x4 works for me. Please let me know if anyone finds a better value, haven't had time to play with it yet. In addition, -H (hash-parallel) should be 2, 0 and 1 were hashing at 1/3 of the speed I got with -H 2.
