For mining Kyan with x11d, it just won't connect with multi-gpu rigs. Just get "timeout" from the pool (mecrypto.club in this instance). And it's really finicky about even getting it to work with individual GPUs, setting the threads to 2 and intensity to 22x128 works on, for instance, an RX5600s and RX5700s, but no combination will hash with RX580 8GB cards.

RX480 4GB cards load any intensity/opencl setting.

start.bash:

#!/bin/bash
#export GPU_FORCE_64BIT_PTR=1
#export GPU_MAX_ALLOC_PERCENT=100
#export GPU_SINGLE_ALLOC_PERCENT=100
#export GPU_MAX_HEAP_SIZE=100
#export GPU_USE_SYNC_OBJECTS=1

# opencl-launch 22x128 with two threads worked; 24x256 didn't
screen -dmS wildrig ./wildrig-multi --algo x11k --opencl-threads 2 --opencl-launch 22x128 --opencl-device 0 --strategy 1 \
-o stratum+tcp://na.mecrypto.club:9484 -u (my_kyan_wallet) -w x -p Annabelle75_$(hostname)_gpu

(mecrypto.club reads the password field as the worker name, hence the juxtaposition)

But intensity of 22x256, anything_x_256 and it won't hash.

Any ideas would be most welcome, and thanks!
