it doesn't work for cuda 2.1 card,

Could you provide more specs? I've verified it works on an NVS 4200m. While not an amazing chip, it's certainly cuda 2.1, equivalent to a "GT 520m."

r9 290 gets 1147MH/s with 1050/1250

Most however just dual mine this coin with Claymore since its more profitable.

For the rest, Marlin is a great miner that offers significant speed advantages over some of the others.

after it i tested with pool and it worked,that was benchmark.and card was geforce gt 720m

Thanks, I'll look into the benchmark on the nvs I have, and verify on a 740.
