Hey guys!

I am getting crazy with my 2nd RIG at the moment! A 6th gpu won't work with ethminer.

My setup:

Mainboard: GA-H110-D3A
GPU: 6x Sapphire RX 580 Nitro+ 8GB

I have done all necessary optimization to my mainboard.

newest BIOS, Mining mode on, internal graphics enabled, blablabla all steps from here:

https://www.gigabyte.com/MicroSite/462/mining.html

My first RIG has the identical setup and had also some problems with the 6th card, but doing all bios optimization the 6th gpu works with ethminer in autostart

my config:

Code:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

start ethminer.exe --farm-recheck 200 -G --opencl-platform 0 -S <somepool> -O <addr>.RIG2/<mail>

Output ethminer:

5 of 6 cards:
Code:
cl  13:51:06|cl-1      Build info:
 cl  13:51:06|cl-1      Creating light cache buffer, size 37223488
 cl  13:51:06|cl-1      Creating DAG buffer, size 2382363008
 cl  13:51:06|cl-1      Loading kernels
 cl  13:51:06|cl-1      Writing light cache buffer
 cl  13:51:06|cl-1      Creating buffer for header.
 cl  13:51:06|cl-1      Creating mining buffer
 cl  13:51:06|cl-1      Generating DAG
 cl  13:51:06|cl-1      DAG 0 %

One card always:
Code:

cl  13:51:06|cl-4      Creating buffer for header.
 cl  13:51:06|cl-4      Creating mining buffer
 cl  13:51:06|cl-4      Generating DAG
  X  13:51:06|cl-4      clEnqueueNDRangeKernel ( -4 )
 cl  13:51:06|cl-4      Switch time 9944 ms / 7028041 us
  X  13:51:06|cl-4      OpenCL Error: clEnqueueNDRangeKernel -4


Its not an GPU issue, the card with this Issue changes everytime. Do someone have any hints for me?

Thanks for your help!
