R9 280x from Nonny12:

cgminer.exe --scrypt -o POOL-ADDRESS -u username -p password -v 1 -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20,-20 --gpu-fan 59,50 --temp-overheat 85,85 --temp-cutoff 90,90 --gpu-memclock 1500,1500 --gpu-engine 1000,1000 --thread-concurrency 8193


I have 4 card R9 280x, only 3 card run and 1 fail.

If I down --thread-concurrency 6000, them run but with big number HW.

Some one help!

Thanks.

my miner with 4 x 280x is running with moded 3.7.2 cgminer an the following config

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
--scrypt -o server -u user -p pw -v 1 -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20 --gpu-engine 1020 --gpu-memclock 1600 --thread-concurrency 8191

3 x 350 kh/s
1 x 230 kh/s (monitor conect on this device)

no rejects
hw errors 0.01% no problem i think

i'm using 4gb of mem if you have more u maybe need to tweak my settings

good luck
Hi gonzzo

My system: Cpu: 3.0 Celeron, Ram 4G, 4xCard Asus R9 280x. I still have problem
3x350 Khz/s
1xoff Khz/s




which miner and os do u use ?

at the moment i have 4 x 355 kh/s,  moded cgminer 3.7.2
config:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o server -u user -p pw -v 1 -I 13 -w 256 -g 2 --lookup-gap 2 --gpu-powertune -20 --gpu-engine 1000 --gpu-memclock 1500 --thread-concurrency 8193 --no-submit-stale

while experimenting yesterday on a other worker with 3 x 280x i had some problems with devices going off, after a reboot the problem was solved (same config) not sure what it was
