I have 2 r9 280x connected, without crossfire on the same motherboard
I use -I 13 -g 2 -w 256 --shaders 2048 and I get a maximum speed of 1100 kh/s.
Do you know what line or what should I do to get around 1400 kh/s?
My fan is at 100 power, tem is steady around 60-65 degrees and i''m using cgminer 3.5.0
my advice is: don't use crossfire , with 2 graphic cards u can get 1400 or 1480kh/s
that script it what i use
cgminer.exe --scrypt -o

my another advice is: if your card is new not burn it now just use 530 kh/s after u can burn ,i know saphire is overclocked but is like a new car u need go easy
thats script run 530 kh/s
cgminer.exe --scrypt -o
