Try intensity 13. (-I 13)
also make sure you set the --scrypt flag in the command line.

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o ** -u ** -p ** -I 13 -g 2 -w 256 --thread-concurrency 8192 --lookup-gap 2 --gpu-powertune 20 --gpu-engine 1075 --gpu-memclock 1500 --auto-fan

try that as .bin file just edit your pool address/worker name/password

do you have the latest ccc and amd sdk drivers installed?
http://support.amd.com/en-us/download
http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/

also you can try --gpu-engine 1040

try changing your TC to 8191 - see what it does.. ;D

also 1500 and 1080 works well you can achieve 750... but also 1040-1060 will be more stable but drop to around 725... nice and solid

just need to play around with your settings, to see what works best - can take days :'(

Use the 13.12 drivers and included runtime. Do NOT use the 14.1 drivers, or the APP SDK 2.9.

Use sgminer 4.1.0.

Run these commands first:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

Use these settings:

Code:

sgminer.exe -o pool.url -u username -p password -I 13 -g 2 -w 256 --kernel zuikkis --thread-concurrency 8193 --lookup-gap 2 --gpu-powertune 20  --gpu-engine 1030 --gpu-memclock 1500 --gpu-fan 80 --scan-time 5 --expiry 10 --queue 0

Start there, and bump the engine up from 1030 to 1035, 1040, 1045, etc until your hashrate drops off, then go back down until it goes back up. That's your shweet shpot.
