Hi I could do with some help optimising my CGMiner. I am running 2 sapphire Dual X r9 280x's. Currently I am running with:
cgminer.exe -o stratum+tcp://ultra.leetpools.com:3335 -u x -p x --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -d 0,1 -g 2 -s 1 -E 10 -v 1 -I 11,11 --thread-concurrency 8192,8192 --gpu-fan 100,30-75 --temp-cutoff 90,90 --temp-overheat 85,85 --temp-target 72,72 --gpu-powertune -20,-20 --gpu-engine 1120,1120 --gpu-memclock 1500,1500 --worksize 256 --expiry 1 --queue 0 --scan-time 1
Any and all advice is much appreciated. I would like to get back up to I 12.

UTC Donations are always welcome :-): UisFWeEn7v6fxBaSmticGdeA6LY7SxdJSV I'm afraid you may have gone a little over my head here. I tried copying this in my BAT file and the application would not run. .bat contains: setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
DEL *.bin
cgminer.exe
- Now create cgminer.conf File (there should be an example.conf in the same directory - Paste my Stuff in there with your Worker Pass and your Pool - run the bat file If u want everything in the Bat it would look around this for the important things: setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
DEL *.bin

Thanks for bearing with me. I've followed the above, but I am getting this message  Below are my current 7970 settings that give me a steady 145kh/s.Those with 280X cards may have to tweak the gpu-engine and gpu-memclock settings a little lower but all the other settings will work. Trust me when I tell you that TC 8192 at the current N-factor will not work or get you anywhere near 130+kh/s no matter what other settings you try. If you try these settings and you still have problems then something else is wrong. If you have 4GB or less of dram these settings will only work for 1 card. If you're trying to run more than 1 card on <4Gb then you'll need to change the lookup-gap setting to 3 maybe 4. If you're running 2 cards with 8GB dram a setting of 2 should work but you may need 3. The more cards you run the more dram you need. If you're short on dram you'll have to play with the lookup-gap setting to compensate. If you run multiple cards you may also have to increase the TC to 18432 to stop HW errors.
