I modded the bios successfully and increased the mining speed to ~14.xxx mh/s with the following settings:
bios mod:
1750 timings -> 1875, 2000
max memory clock 2000 -> 2200
amd radeon settings:
gpu clock -> 1125 (underclock)
memory clock -> 2000
fan -> 100%
ASIC is 65% and 75% so they run 60° and 53°. Memory is Micron 4GB.
Could push the memory clock further now but I'm satisfied and let them work for 48h.
I think they could do 15.xxx mh/s but with much more power draw and heat dissipation.
And disable crossfire in amd tool, enabled by default!
