i use cuda miner like this>
cudaminer.exe -d 0 -l 4x2 -o
www.guugll.eu:17327 -O walletAddress:Password -i 0 -C 0 -s 5 -m 0 -D
this is for laptop with very low power but it can still do REC
you can use it like this for auto tune>
cudaminer.exe -d 0 -o
www.guugll.eu:17327 -O walletAddress:Password -i 0 -C 0 -s 5 -m 0 -D
on my desktop i use this>
cudaminer.exe -d 0 -o
www.guugll.eu:11327 -O walletAddress:Password -i 0 -C 2 -s 5 -m 1 -D
i try FTC with the desktop
try this - i believe it must work, if you get the same error you have bad network (maybe some ports are closed or...give us more logs...)
