I am seeing about 410kH/s with the same card.
Flags are: --scrypt --thread-concurrency 14208 --intensity 18
All other parameters use default values.
The system is running Fedora 18 with 4GB memory.
cgminer 2.11.4

Tried these settings with litecoins, and besides having to tweak the thread concurrency down to 8000 to get cgminer to start, I'm getting right around 400 on each card! Thanks!

After sending that reply I updated to cgminer 3.1 and also found it necessary reduce thread concurrency to run. I couldn't find suitable values to get back to 410kH/s, so for now have reverted to 2.11.4.

Any ideas how to increase my hash rate mining BTCs?

Thanks again for the input so far!

Glad to be of help. Sorry, it has been a while and I no longer have the settings I used for bitcoin. I think I was getting around 440MH/s with very minimal tweaking.
