i have 13gpu rig: 6x hd7850, 2x r9 270, 5x rx550 1.6.7 failed on both r9 270 another 11 gpu working good
version 1.5.9 working good with all 13 gpu
how i can fix this
I think R9 cards are supposed to be kernel 2, not kernel 1.
Thats right, you should set it by hand to use kernel 2 in gpu_conf
I tried my r7 370 with both version of kernels and can't start it, so this is not problem about kernels, it looks like a some kind of bug in this new versions of miner.
Is your R7 Pitcairn architecture? I have a R7 240 and its Oland architecture, which I dont believe newer SRB supports.
