Most mining software has dropped support for very old cards where it just isnt reasonable to expect miners to use. Ethminer is opensource and supports just about all cards. There just arent very many Titan 6gb these days.
that's right. But strange thing - phoenix 5.5c can mine GT770 (cuda 3.0) with no error at 2-3MH. My Titan is corupted? Games going ok..
