Hi Guys,
I have recently bought a sapphire radeon r9 280x for litecoin mining.
I have tried several different cgminer settings and so far this is giving me the best results so far ( 700 kh/s )
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt --intensity 13 -g 2 -w 256 --lookup-gap 2 --temp-target 70 --auto-fan --temp-cutoff 90 --thread-concurrency 8192 --gpu-engine 1000 --gpu-memclock 1500 -o stratum+tcp://world.wemineltc.com:3333 -u workername -p password
Ive read people get 750 kh/s with this card, so if anyone can help me out with that?
I tried playing with thread concurrency and set it to 11200, also set memclock lower but none of those help.
Also i heard about undervolting the card, but i am not really confident doing that.

You should be able to get at least 735-740. Try changing TC to 8191 and gpu engine to 1045 or 1050.
Just mess around with the values of gpu engine and TC. You'll find a sweet spot.
