Finally Crimson 16.7.3 seems fixed the R9 380/x black screen issues. However, after two days, my PC suddenly reboot while I was playing GTA V, after rebooting the system AMD settings notified that "AMD WATTMAN has been restored to default settings due to an unexpected shutdown". And I can't find any event log error about this sudden reboot.
Before using 16.7.3, I was using CCC 15.11.1 and it was all fine, but lack of optimizations.
INTEL I5 6500
NEOECO II 550W PSU
DDR 8GB RAM
No problem with CCC 15.11.1.
I have seen this message too and i am not using an RX GPU, i think it's a bug. I'll share the feedback internally, thanks.
