Hardware optimization (R9 290x)

[lyon42]

Hi,
I mine with two R9 290x. I have 1500Kh/s (~750 per card).
But some people have 850-950 with this card.
How can I optimize my config ?

cgminer 3.7.2 with this config

R9 290x Sapphire cgminer config: (893khs)


setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
color 02
cgminer.exe --scrypt -o stratum+tcp://ltc.cryptoworld.eu:3333 -u barthyczg.5 -p x --intensity 20 --thread-concurrency 32764 -g 1 --lookup-gap 2 --worksize 256 --gpu-engine 940 --gpu-memclock 1500 --gpu-powertune 20

This config gave me an error, too much thread.
With another config I have 1740Kh/s (~870Kh/s per card) \o/
