4K UHD 630 i9 9900k

[gillangit]

I successfully installed hackintos 15.x UHD 630 with this config but it doesn't run at 4k 60fps while it runs at 2k resolution, what should I fix?I have allocated Bios DVMT to 64MB, then I have also tried deleting framebuffer-stolenmem but it can't boot

Delete framebuffer-fbmem, framebuffer-stolenmem, and framebuffer-unifiedmem.
Change the ig-platform-id to 3E9B007 (reversed).
Also, you shouldn't require spoofing the device id as its natively supported.

hi thank you very much for your answer, I found the problem is that the igpu uses the hdm 4.1 port which only supports 4k 29hz, I tried changing the dvmt to 128mb and the dgpu(RTX 2070 Super) is detected as an extended monitor with a 4k 60hz scale but the problem is only the mouse with a black screen without anything and the mouse cannot be moved, is it possible to use igpu acceleration and use the dgpu only as a DP port to the monitor, is it possible?

Probably, you meant 1.4? Why not use the DP instead if 4K is limited on your hardware?

As none of the RTX models are supported on ANY OS X/macOS version, its better to disable it via SSDT or Device Properties or boot args. Once you do that, only IGPU will be available to macOS and you'll have to use the display using the onboard ports.

Don't think so unless the dGPU is compatible with macOS which isn't in your case.

yep that's right i made a typo hdmi 1.4 that means my pc is only limited to 2k. okay i understand now, thanks for the answer. my onboard port only has hdmi 4.1

Well, as per the official datasheet, your board (if its the one in your profile), it has 1xDP and 1xHDMI.

Do the following and you should be good:
- Set the DVMT back to 64MB and disable the dGPU
- Delete framebuffer-fbmem, framebuffer-stolenmem, and framebuffer-unifiedmem.
- Change the ig-platform-id to 3E9B007 (reversed).

You should be able to use at least 4K@30Hz on macOS via HDMI. Just make sure to use a certified cable.

Thanks bro,
I have a Maximus XI Code motherboard, it doesn't have DP. its only HDMI, other port is USB Type-C

Yes, double checked. The USB Type-C port probably doesn't support display. However, you can use 4K @30Hz. The other option is to use a compatible AMD GPU.
