So, this issue never happened before 10.14.4, I have RX 560, Z77, 1230 v2 and 16GB RAM, I installed 10.14.4 for GPU video decode and encode, both of which worked great with iMacPro 1,1 SMBIOS, but it brings anther issue that after wake from sleep, if i try to use the GPU very hard, such as playing multiple streaming video in adobe flash format, the GPU fan could go to 2500 RPM and up, making a lot of noise. this only happens on 10.14.4 and only after wake from sleep. so i tried to locate the issue via log. here is what i found:
1. first sleep the computer and wake by clicking mouse, check the log, system wake up at 2019-02-21 05:43:41
as you can see there is an error massage: kernel: (AMDFramebuffer) CRITICAL ERROR : VUPDATE interrupt has not been generated in time!
tried to google around, but nothing helps.
any idea?
EDIT: this issue still exists on 10.14.5 beta1 and beta 2. Workaround cable method solved this issue perfectly. see post #10 and #37.
EDIT: macOS 10.14.5 beta 2 (18F108f) fixed the fan speed issue after wakeup from sleep, it is confirmed with Sapphire RX 470 Nitro 4GB.
1. first sleep the computer and wake by clicking mouse, check the log, system wake up at 2019-02-21 05:43:41
Code:
log show --last 4m | grep -i -E "wake reason"
2019-02-21 05:43:34.896762+0800 0x241 Default 0x0 56 0 powerd: [powerd:sleepWake] Wake reason: "<private>" identity: "<private>"

2. check gpu related log:
Code:
log show --last 4m | grep -i -E "amd|radeon|gfx0"
