400 is quite low. What are your clocks at now? What's the highest memory speed you can get?
And just do -I 13 untill you figure out your best clocks, then worry about the flags.
Delete all the .bin files inside cgminer's folder.
Also, do you have the --scrypt flag there? You should be getting KH/s and not mh/s...
Then try these:
-g 1 -v 1 --lookup-gap 2 --intensity 13 --gpu-engine 900 --gpu-memclock 1500 --shaders 1792 --auto-fan --temp-target 70
Start cgminer, then hit G, then C, and lastly hit M to change memory clocks. Go up in 25mhz increments till it crashes or you get HW.
After finding the max stable memory clock, proceed to find the ideal core to mem ratio.
Eliminate the .bin file again.
So, say you hit 1700mhz mem, then just hit G, C, and E to change core clock. Start at 850 and work your way up in 10mhz increments till hash rate stops increasing or drops. Then go back down in 5mhz till you find a spot where hash rate pops noticeably higher. You should find an approximate area and then find the exact freq changing 1mhz at a time, up and down till hash rate is REALLY stable and you get lots of wu:xx/m and U/m as well as little to no R, GF and RF.
Go back to cgminer's folder and look for the scryptblabla.bin file. There should be a TC24000 or so value. Write it down and replace --shaders 1792 with --thread-concurrency "said value".
Last step is to find the max intensity cgminer can run at, which is easy too. Just start cgminer again after setting a fixed thread concurrency and hit G, I and try to get to 19 or 20.
The pc will be impossible to use while mining, if you want to mine and browse or whatever use d as intensity value.
That should be it.
After you do that
