Hi Community,
I've just revamped my Hackintosh with a new AMD R9 390X (Gigabyte G1 GV-R939XG1). I have two monitors connected at 4k@60Hz.
As per research iGPU is enabled by default and the frame buffer is set to use "RADEON". No other device IDs are set and is registered as "AMD Radeon HD 8xxx 8192 MB" on boot.
After running the machine for 1.5 hours, it becomes slow and then grinds to a halt. It turns out that the ATI GPU runs really hot because it's continually under load. As per other threads, the GPU by default relies on the Windows drivers under fuzzy logic fan control. I've gone ahead and flashed the BIOS under Windows increasing the fan speeds to keep cool under continuous load. Running for 6-8 hours the GPU starts ghosting windows on the secondary screen. Temperate/utilisation doesn't change between one or two DisplayPort 1.2 outputs.
The processor shouldn't be sitting at this high utilisation otherwise the life of the GPU will be really really short. What am I missing?
Cheers,
Elijah
