I think that this one is iStatMenus reading values issue. Because gpu port is limited to 50W, or it will do emergency power off if power consumption will be higher.Is that power reading on MacOS accurate? Or is that the combined power of CPU and GPU?
Otherwise the WX4150 uses 70-80W on MacOS, but only 32-35W on Windows?
But still under MacOs when using some Adobe apps, the ram frequency drops to 300 mhz, and this happens only on discrete mode. That is some kind of driver issue i think. As wx4150 is the first my AMD for mac, i almost nothing know about it
FOR FUTURE VBIOS BUILD FOR 4170
I found the reason why Catalina won’t work with HP vbioses! The reason is Memorytraininginfo and memorytraining command . The easiest way to get 4170 Affleck and Aomorhid work on Catalina is disable Memorytraininginfo, delete module and replace memorytraining command from Polaris vbios that not contains Memorytraininginfo.
The second way is use Apple 560x vbios, replace modules section with 4170, then replace Memorytraininginfo with Apple one and patch vbios header, decode it and make it same function as 4170.
Here is some proves how 4150 with same problem but dirty patched header:
Anyway latest build working fine on Catalina, because does not have memory training function
