) If you have the same cards, it doesn't mean that they all can handle the same intensity. Try setting every card separately in "gpu_conf". Experiment and find the best setting. Some cards even work better without the double_threads option turned on!
) I know you like to monitor your GPU while it is working, but if you close GPU-Z, you will get a better hashrate.
) If you get a "Error CL_MEM_OBJECT_ALLOCATION_FAILURE when calling clEnqueueNDRangeKernel" error, increase virtual memory.
) If you get something like "Warning: threadx hashing speed is 0 (x)", that probably means you need to lower your intensity. Auto intensity is not magical always, sorry.
) Try making a custom config, start with low intensity and go up until you find one that does not crash :
"gpu_conf" :
[
{ "id" : 0, "intensity" : 10, "threads" : 2, "worksize" : 8},
{ "id" : 1, "intensity" : 20, "threads" : 2, "worksize" : 8},
{ "id" : 2, "intensity" : 30, "threads" : 1, "worksize" : 8},
{ "id" : 3, "intensity" : 40, "threads" : 1, "worksize" : 8},
]
) If you are having the "quits after 3 minutes or pressing h" problem put --adldisable in start.bat :
FOR /F %%x IN ('tasklist /NH /FI "IMAGENAME eq %EXE%"') DO IF %%x == %EXE% goto RUNNING
%EXE% -c config.txt --adldisable
TIMEOUT /T 15 /NOBREAK
) For Hawaii cards best setting for 'normal' and 'normalv7' is intensity:0 and double_threads:true
) Possible Vega hashrate drop fix
) If you have Vega cards, go to your windows power saver settings, and set it to performance. After that set your monitor never go to sleep.
