Best 7950 settings?

Ok so I recently got a cheap asus 7950 and I was wondering if anyone has any good cgminer settings I could use? At the moment I am getting 600 KH/s (Not counting the %5 rejects) with this: cgminer --scrypt -I 20 -g 1 -w 256 --thread-concurrency 24000 --gpu-engine 1100 --gpu-memclock 1250 --gpu-vddc 1.087 --temp-target 65 --auto-fan -o stratum+tcp:/.... -u x -p x
Also what would the expected hashrates be?

I don't have any 7950's so I can't say what the expected hashrates are, but just read through ckolivas notes on optimizing GPU and follow his steps:
https://github.com/ckolivas/cgminer/blob/v3.7.2/SCRYPT-README
The only thing I can note about your settings is that you have a very low temperature target. I believe the safe limit as set by AMD is 95 degrees. Personally, I try to target around 80.

Does it make a difference which 7950 you have? I bought a few from Sapphire. Thanks

1. there is a compiled scrypt binary that increases 7950 speeds by 20KH/s somewhere in these forums -- track it down.
2. TC of 20000 is what I use - optimal with above binary
3. Intensity 20 seems steads
4. 1100/1500 was giving me the best hash rates but was unstable.. Switched to 1075/1250 and the hash rates dropped an acceptable amount for the stability and energy savings provided. Hashing at about 640kh/s.
4000 chars available and all I got was this stupid tagline.

I used to run my 4 msi twin frozr 7950 cards at 1050/1250 getting 655 each card at 1.044v then I dropped them to 1000/1250 and only lost 5khashes each card but saved on power.. so win for me.
If you like what I've posted, mine for me on whatever algo you like on
