The UHD 770 can boost up to 1.65 GHz (depending on CPU model, e.g., i9-13900K). In Windows, the power management (Intel DTT) aggressively downclocks the GPU to 300 MHz at idle. In macOS, however, the Power Management stack doesn't have the same fine-grained control over Intel’s GT clock. Many users report that the GPU frequency sticks to a "Mid" state (around 800-1000 MHz) even on the desktop, generating unnecessary heat.
Underneath, in smaller handwriting, he added: “RUNS TOO HOT.” uhd 770 hackintosh hot
In macOS, the UHD 770 has . Apple never used these chips. Hackintoshers spoof the iGPU as a supported model (usually Kaby Lake or Coffee Lake ). This causes: The UHD 770 can boost up to 1
Most users find success using MacPro7,1 or iMacPro1,1 for these builds, as they are optimized for systems with dedicated graphics and high core counts. Many users report that the GPU frequency sticks
Now go build that silent, cool-running Sonoma machine.
