Why with this bat i have only 400kh/s whit my r9 280x?
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --verbose --scrypt -o stratum+tcp://fry.minebig.com:3341 -u xxxxx -p xxxx --thread-concurrency 11200 -I 13 -g 2 -w 256 --gpu-engine 1080 --gpu-memclock 1500

What i must change?

Try removing after your password and add this: --lookup-gap 2 --thread-concurrency 8192 -g 2 -I 13 --auto-fan --gpu-fan 30-75 --temp-cutoff 90 --temp-overheat 85 --temp-target 75 --gpu-memclock 1500 --gpu-engine 0-1050 --gpu-powertune -20 --no-submit-stale

Thats what I use on my 280x Asus Matrix and I get about 750-780 khs

I've tried, one gpu @500 kh/s one @400 Kh\s Huh

try --thread-concurrency 24000 -g 1

or it may be low ram

that's only good for 7950. Wont work for 280x
-g 2 --thread-concurrency 8193 -I 13 is the best you can do with 280x

I see one 280X on the scrypt comp page using this...

-I 20 -g 1 -w 256 --thread-concurrency 20992

its worth trying as your half rates match what happens to a 7950 at I 13 vs I 20

With this both at 450 kh/s... i dont understand!

If that worked for you and both match hashrate now... try my 7950 bat file...

Code:

setx GPU_MAX_ALLOC_PERCENT 100

setx GPU_USE_SYNC_OBJECTS 1

cgminer.exe --scrypt -o stratum+tcp://pool:port -u xxxx -p xxxx -I 20 --thread-concurrency 21712 -g 1 --gpu-engine 1050 --gpu-memclock 1500 --gpu-powertune 20 --gpu-fan 90 --temp-cutoff 85 --scan-time 1 --queue 4 --no-submit-stale

I changed my values to match what you have above for your clocks.

I know its an older card, but better than a kick in the head! Can you tell me the optimal settings for a 5770? I want to get every last hash outta this sucka!! If you don't know, perhaps point me in the right direction? Anybody?
