Hi, i have 2 gtx 770 graphics cards i purchased from amazon, but before i send them back, broken or not due to no warranty on these cards... on amazons return 30 day policy lol i wanna cuda mine them for fun and then send them back.

Well i wanna get a evga card that has warranty, and a friend thought why not cuda mine them to oblivion.

So how do i get it started?

I searched around and my i have 2 gtx gigabyte 770 4gig oc edition in sli, but the evga 780 ti king pins much better in all aspects compared to both those cards, and has warranty.

So what's my cards flag number,is it the same as 670.

Currently i have downloaded cuda miner:

1 download cudaminer
2 opened a bat file, not sure what to put in it as newbie
3 Choose a pool, not sure what, maybe maxcoin or altcoin, prime coin not sure, some coin, newbiecoin.

Hows it work

cudaminer.exe -d gtx770 -l K7x32 -C 2 -i 0 -o stratum+tcp://stratum01coins.net:3333 -u Worker -p password
Or
cudaminer       -d gtx770 -l K7x64 -C 2 -i 0 -o http://stratum01coins.net:3333 -u Worker -p password
Or
cudaminer.exe       http://stratum01coins.net:3333 -u Worker -p password
I can't work it out

I get nothing but errors, and no card detection, 

Well i don't know was curious that's all.
