This worked perfectly for VTC: --algo=scrypt:2048 -d GTX780 -H 1 -C 1 -d 0 -i 0 -m 1 -l Z10x24
Getting 307kh/s super stable at 1293/1800mhz with 1150mv.

Apparently, it wasn't my oc that was causing issues, but rather my cudaminer config...I like this, pretty fun to tweak with xD
And this seems to be more profitable than maxcoin, despite me hashing at 203mh/s.
Christian, if you can make a prime gpu miner with Supercomputing's help I'll be thrilled

Green team ftw :p
Still missing proper UTC settings for my 780, but if I find stable and good ones I'll post here.
Are you mining in a pool? I don't find a pool for VTC that is good as i want, every time a lot of 'booo' :p
