That is great , i can make my cards work on all the algos just not n-scrypt , what is your config like for this one ? ( as in your .bat is like? ) I have asus 750's too
Try
cudaminer.exe --algo=scrypt:2048 -o pool address -u user -p pass -H 2 -i 0 -m 1 -l T5x20 With this config i have ~155 khash/s each card, but overclocked 750Ti 2Gb. Replace
-l command to
-l auto and when miner find you optimal configuration change
auto to kernel prefix with launch configuration. Good luck!
