Hello,
First of all, good work Christian. Applause!
I have a GTX 295 (2 GPU's). The first version of the cudaminer performs a bit better than the latest(09/04) one. Between 1 a 2 Khash/s better.
Without overclocking I get +-36 Khash/s on each GPU.
Tested for bitcoin mining (not a cudaminer), and there it went to +-52 Mhash/s on each GPU.
Should I be able to get more or less, litecoin whise mining?
What do I have to overclock/underclock to be efficient?
Bitcoin uses SHA-256 where as Litecoin uses scrypt for proof of work. Scrypt is much more memory intensive, so it's a world of difference.
