I try enable onboard GPU for Display output, so my HD4670 have 100% available resources, basically become Dedicated OpenCL. but...
when enable onboard GPU, AMD OpenCL become unavailable... =(
Did you try putting a monitor or dummy plug on it?
Yes I did, even try 2 monitor in different GPU's, just AMD GPU dont have display, (since I set BIOS to initialize onboard GPU first)
