I cant remember what version i was using because i overwrote it with this version, i downloaded it about a month ago, which would have been the latest version at the time..
I didnt even use any launch configs with that version and i got 45 KH/s
Im thinking of going back to it if i can find a link to the earlier versions.
I only downloaded this version to mine vertcoin, which is really no point with such a low powered card anyway, the hashrates im referring to are for any scrypt based coin such as dogecoin and flappycoin etc.
You know, now that I think about it, I had the pleasure of working with a GTX 275 earlier this week and saw fairly similar numbers.
One thing to try, look at rolling back to the 332.21 Drivers. Some have noted a drop in hash rate with the newest drivers especially on older models. In addition it is not a bad idea to go back to a previous version of CudaMiner for a card that old as legacy cards are just not supported anymore (though the F and f kernels are your best bet in the recent versions).
