Hi ,

I bought today a R9 280X sapphire !!!

My KH/s si actually of 580

with

Intel core Duo2 E8400 @ 3Ghz
4 Giga Memory at DDr2
ModtherBoard : PQ5

Windows 7 x64

My script connexion :

Frist file :
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

Second file :
cgminer --scrypt -o stratum+tcp://usa.wemineltc.com:3335 -u XXXX -p XXXX--intensity 13 --auto-fan --temp-cutoff 90 --thread-concurrency 8192 --gpu-engine 1100 --gpu-memclock 1500 --temp-target 70

Actually, my temperature is 80°C not more...

I can't put over -I 13 , otherwise i got some HW...

Any idea to get better score ?
