Hardware: CPU: Intel Core i3-4130 CPU @ 3.40GHz (Haswell) GPU: Oland XT [Radeon HD 8670 / R5 340X OEM / R7 250/350/350X OEM] (R7 250 written on card) RAM: 8.00 GB Kingston DDR3 (4096 MB x 2) Motherboard/Laptop model: H81M-DS2V Audio Codec: - Ethernet Card: built-in Wifi/BT Card: -
What guide/tool followed: https://dortania.github.io/OpenCore-Install-Guide/config.plist/haswell.html#starting-point https://dortania.github.io/Getting-Started-With-ACPI/Universal/spoof.html https://www.tonymacx86.com/threads/gpu-ssdt-not-working.310705/#post-2230719
What part I got an issue with: Cannot spoof the GPU from R7 250 to R7 250x, it only appears as Display 7 MB.
What files/config I am using: Here you can see few configs that I have tried, and a list of PCI devices. https://gofile.io/d/sbsLJr
Extra Info: I have tried the Dortania SSDT spoof, then similar SSDT spoof as in tonymac post (linked above). Then, I have tried adding entry to DeviceProperties in config.plist, in various ways, with WhateverGreen turned off and on. Each time, the I get the same boot with 7MB GPU in 1080p resolution. The only progress was renaming the Display to custom string (in About This Mac).
Other than that, it is stable, no flickering, no issues.
Is it important to do a NVRAM reset to apply changes of GPU config?
How to determine the AAPL,slot-name?
