A hot Hackintosh usually means your CPU cores never enter deep C-states (C6/C7/C10). Because the iGPU is inside the CPU package, if the cores are awake, the iGPU VRM stays active.
By using specific parameters inside your boot configuration, you can pass fake device IDs to simulate an older engine: Target Device Location : PciRoot(0x0)/Pci(0x2,0x0)
Before modifying your OpenCore config, rule out physical issues. Use (for macOS) or HWiNFO (via Windows dual-boot) to check these metrics.
Example (simplified):
The lack of official support has sparked a "hot" wave of experimentation within the Hackintosh community. Builders are trying to force the UHD 770 to work through a few creative, though not always practical, methods. uhd 770 hackintosh hot
If you are running a "hot" UHD 770 alongside a discrete GPU (AMD Radeon RX 6000/7000 series), macOS might keep the iGPU awake for compute tasks or DRM decoding (Apple Music, Netflix). This "headless" mode prevents the iGPU from sleeping—resulting in constant 45-55°C idle temps.
For CPUs with "F" variants (e.g., 12700KF), which lack an iGPU entirely, you have no choice but to use a compatible dGPU. For non-"F" CPUs, just ensure the iGPU is disabled.
The search term is currently one of the hottest, most debated topics in the desktop custom-build community . If you are building a modern PC using an Intel 12th, 13th, or 14th Gen Core processor (such as the i7-12700K or i7-14700K), you will quickly find out that it comes equipped with Intel UHD Graphics 770 .
Here is the hot configuration for UHD 770 running macOS Sonoma 14.x / Ventura 13.x: A hot Hackintosh usually means your CPU cores
In DeviceProperties , you can set framebuffer-patch-enable to 1 and framebuffer-stolenmem to 00003001 (19MB). 3. Physical Solutions: Tackling Heat via Hardware

You cannot rely on PciRoot(0x0)/Pci(0x2,0x0) auto-detection. You must inject properties.
Search for "UHD 770 Hackintosh Hot" on any forum, and you will find a chorus of users complaining about idle temperatures spiking to 55°C, VRM throttling, or the heatsink becoming a space heater just by moving the mouse. Use (for macOS) or HWiNFO (via Windows dual-boot)
AMD Radeon RX 6600, 6600 XT, 6800, or 6900 XT . These have native drivers in macOS and provide excellent performance.
Option 1: The Gold Standard — Dedicated AMD GPU (Recommended)
The modern hardware community is hyper-focused on Alder Lake, Raptor Lake, and subsequent Intel desktop architectures because they provide incredible computing power for the money. Unfortunately, they also present unique structural challenges for macOS setups:
