okay here some settings I'd tried:
cgminer.exe --scrypt -o "http://fc.ltcoin.net:6666" -u "username" -p "password" -I 13 -g 2 -w 256 -shaders 2048
cgminer.exe" --scrypt -u "username" -p "password" -o "http://fc.ltcoin.net:6666" --gpu-platform 0 -d 0 -w 256 -v 1 -I 20 -g 1 -l 1 -T --thread-concurrency 15508
cgminer.exe" --scrypt -u "username" -p "password" -o "http://fc.ltcoin.net:6666"
(cg miner with scrypt now crashes - tried 3.1.1 and 3.2.1 but same result)
minerd.exe --algo scrypt --scantime 99 --url http://fc.ltcoin.net:6666 --userpass username:password --threads 99 --retries -1 -P
Greetings!
I see that you are using the --gpu-platform argu do you have more than 1 gpu installed? are you pointing to the correct one?
