The HD 530 injection might be the problem, SKL CRB is workable without injections it is the same thing. We just went through this with the HD 4600 AML injection issue and RX 480 support. My AMD R7 265 can be recognized as a R9 270X but it requires injections and fixes. If I let it detect natively without any injection its an AMD 7XXX card without any fuss. Performance is the same, its just a name (cosmetic) but they use the same drivers.
View attachment 224153 It has metal support 30 bit color. Yes it has flickering in the top left like 530 without the fix, but I only look at clover screen for this connection, the top left is irrelevant to me because my screen is connected to RX during use. If it will run a Valley Extreme HD bench its not all that bad.
