The most effective way to gain acceleration and reduce heat on UHD 770 is to spoof it as a UHD 630 (Coffee Lake) in your config.plist . While you lose some advanced hardware decoding features, you gain a functional, cool system. Set to 0x3E9B0007 (Desktop). Device ID: Spoof as 0x3E9B or 0x3E98 . 2. Configure WhateverGreen Kext
This is where the "hot" keyword becomes literal. Because the UHD 770 is masquerading as an older UHD 630, the driver matching is imperfect.
: Without proper drivers, macOS defaults to a basic VRAM mode (often showing only 7MB or 14MB of video memory). User Experience uhd 770 hackintosh hot
Generate a custom SSDT-PLUG.aml using CorpNewt’s SSDTTime. This tells macOS that your 1700 CPU supports native C-State management. Deeper C-states = Cooler iGPU.
Do NOT use 07009B3E if you rely on the iGPU for driving a 4K display output without a dGPU. If you are iGPU-only, use 0A00803E but add -igfxblr (igfx bypass link rate) to boot-args to prevent overzealous link training. The most effective way to gain acceleration and
Users frequently report that their Hackintosh runs hotter on idle with UHD 770 compared to Windows or older Hackintosh builds.
Enabled (Ensure DisableIoMapper is checked in OpenCore if you face boot loops). The Ultimate Workaround: Adding a Supported dGPU Device ID: Spoof as 0x3E9B or 0x3E98
While acceleration is possible, this setup is not without its quirks. Users often report the following "hot" issues that require additional troubleshooting:
agdpmod=pikera : Essential if you switch to a dedicated AMD dGPU later, preventing black screens on display wake.
Before diving into configuration, it is vital to understand what works and what does not.
