How much RAM is on the PC?
Maybe
--scrypt -o stratum+tcp://stratum.give-me-ltc.com:3333 -u USERNAME -p PASSWORD --thread-concurrency 5632 -g 1 -w 256 -I 9

4GB of Ram mate.
And nah it's Winter here in Australia, so the temperatures here are getting colder (:
EDIT: Tried that mate nothing good happening now


All my cards are working fine for BTC mining.
