Bump up your intensity. 13 is too low, you should be able to do 19.
Check this post out on tweaking your card.

Sorry about bumping an old thread, but this might help someone searching. This should give you a nice 420-430KH/s baseline to tweak from.....also make sure your Windows power options are set to High Performance...Control Panel>Power Options. Delete any .bin files in your cgminer folder....
Create a .bat with this:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://us-east.chunkypools.com:6666 -u Xardas.1 -p 123 -I 19 -w 256 -g 1 --thread-concurrency 15232 --gpu-powertune 20
Next you can do some tweaking to GPU engine and mem. Getting 450KH/s isn't very hard and the card should run ~70C@40ish% fan speed depending on your ambient.

getting 435 with xfx 270x
hope this helps going to run hot 85c -90c

A friend of mine is using a Sapphire 270X Vapor-X 2GB gpu. But the most he can get from this card is 350KHash/sec.He is using AMD Catalyst 13.12 and the following setting:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://url:port -u username.workername -p password --no-submit-stale -I 13 -g 1 --thread-concurrency 8192 --lookup-gap 0 -w 256 --gpu-engine 1120 --gpu-memclock 1500 --auto-fan --auto-gpu --temp-target 70 --temp-overheat 80 --temp-cutoff 85 --queue 3 --scan-time 40 --expiry 120 --gpu-powertune 20
He can't set TC higher than that without setting the LG higher. Any help would be greatly appreciated.
