Print Page - cgminer 3.7.2 - 3x R8 280x - GPU 0/2 failure, disabling!

Hello everyone!

I recently got a computer to start mining and I have a little problem...
My configuration is:
x3 MSI radeon R9 280X (http://www.ldlc.com/fiche/PB00158918.html)
x1 ASUS Z87-A C2 (http://www.ldlc.com/fiche/PB00152011.html)
x1 Be Quiet ! Alimentation (http://www.ldlc.com/fiche/PB00131168.html)

And I am running cgminer 3.7.2 and this is the .bat file I made to start tuning my graphic cards:

Code:

setx GPU_MAX_ALLOC_PERCENT 100,100,100 
setx GPU_USE_SYNC_OBJECTS 0,0,0 
cgminer --scrypt -o pool_link -u zat1991.test -p password -I 13 -w256 -g 2 --no-submit-stale

Here is the error I have:

I tried to open 3 sessions of cgminer using the option --device x with x the number (0,1 or 2) of my GC but it doesn't work... The first session is fine (600kH/s) the second awfull (27kH/s) and the last one freezes.
I also tried with guiminer (an old version that enables to set some parameters, the alpha version to be more precise), using 3 different tabs and it works... But I cannot tune my GC this way.

I am totally lost so if you got any idea that could help... Thanks a lot and have a good day

p.s.: If you need some presentation of myself as I am a new member, feel free to ask.

del *.bin
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 0
cgminer --scrypt -o ltc.ouranos.fr:port -u zat1991.bastien -p password -I 13 -w256 -g 2 --thread-concurrency 8192 --gpu-engine 1050 --gpu-memclock 1500 --gpu-powertune 20 --gpu-vddc 1.125 --no-submit-stale
