So... I've installed my 280x (ASUS R9280X-DC2T-3GD5) yesterday and having a hard time to get more than 575-600 kh/s with it.
Windows 7
Catalyst 13.12
cgminer 3.7.2 with:
"gpu-threads" : "2",
"intensity" : "13",
"worksize" : "256",
"shaders" : "2048",
"thread-concurrency" : "8192"
GPU core clock is 1070mhz
CPU mem clock is 6400mhz
GPU temp is around 74celcius (fan at 55%)
Increasing Intensity gives me hardware errors
what else can be done?
I get 750 kh/s from the same card..(its the middle one in the settings below
-g 2 -w 256,256,256 -I 13,13,13 --lookup-gap 2 --thread-concurrency 11200,11200,8192 --temp-overheat 92,92,92 --gpu-engine 1035,1080,1080 --gpu-memclock 1500,1500,1500 --gpu-powertune 20,20,20 --auto-fan
