Anyone getting good hashrates running a 7970 + cgminer + Litecoin?

Ive been having nothing but trouble trying to get consistant hashing over 550kh/s. I can get 650-700 for 20 minutes and then i get drivers crashing. Windows 7 64bit. Temps are below 80C on the GPU and below 90C on the VRM. Ive run furmark for an hour straight to rule out it being a bad card. Ive tried many different driver setups, 2 fresh installs.

This might have something to do with it...

Please list the catalyst version you are running, amd app sdk version, and your command line for cgminer + hashrate.

Im willing to pay in litecoin for a consistant 700kh/s.

Code:

--auto-fan --gpu-fan 50-100 --gpu-powetune 20 --gpu-engine 1023 --gpu-memclock 1690 -I 13 -w 256 --thread-concurrency 8192 -g 2

Set your memory clock as high as you can get it without crashing, set your core clock at (memory clock * 0.605).
