target to have latest stable OSX ( Catalina ) on my pc, initial spec:
CPU: Ryzen 2700x
Ram: 2* 2x8GB delta-rgb-tuf-ddr4 3200MHz https://www.teamgroupinc.com/en/product/delta-rgb-tuf-ddr4 (all 32GB at 4 RAM slots)
Motherboard: Asus B450-F Strix
GPU: Asus 1080ti Strix
Storage: some SSD and HDDs
Monitor: Asus PG279Q and Dell UD2719D
PSU: Corsair RM1000x
Case: Phanteks Evolve ATX + Fans
#1 hardware
#2 trying to install hackintosh catalina without the 1080ti, only RX 580 at second PCI-E slot
followed snazzylabs guide
,
-> failed, perhaps miss some steps / not paying attention
2nd attempt followed techturnerlife
guide and literally just download files he provide to create bootable USB
+ update EFI partition at the SSD with clover with content from bootable USB after login to catalina
#3 making dual gpu works for both OS
need to disable 1080ti at OSX
without disabling any PCI-E slot, cumbersome and B450-F seems not support the feature
make the both GPUs work optimum with the list of HW above for gaming at windows and also doable with OSX without plugging / unplugging GPUs or their HDMI / DP cables,
the setup:
pci-e slot | GPU | port | monitor
-------------------------------------
PCI-E 1 | 1080ti | DP. | PG279Q
PCI-E 1 | 1080ti | HDMI | UD2719
PCI-E 2 | RX580 | DP. | UD2719
PCI-E 2 | RX580 | HDMI | PG279Q
tried several easier methods found at internet, the one that works: SSDT method
ref:
my summary of following the guide to disable nvidia 1080ti at osx:
it works
not working:
audio from motherboard audio jack after using the disable GPU ACPI patch
audio jack from monitor ( both DP and HDMI ) works, but can't natively control the volume
to make windows appear at Opencore uefi, make sure windows installed with GPT partition https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10
thank to everyone who provide the guides / stories

#1 hardware
- allocate one of SSDs for OSX Catalina
- nvidia 10x won't work, so i added Asrock RX 580 8GB
#2 trying to install hackintosh catalina without the 1080ti, only RX 580 at second PCI-E slot
followed snazzylabs guide
-> failed, perhaps miss some steps / not paying attention
2nd attempt followed techturnerlife
- motherboard BIOS setting: disable fastboot and CSM
- boot from bootable USB
- at initial OSX screen, format the target SSD with macos appfs format then install catalina
+ update EFI partition at the SSD with clover with content from bootable USB after login to catalina

my summary of following the guide to disable nvidia 1080ti at osx:
- put 1080ti back to 1st slot while keep the AMD RX 580 at second slot and boot to windows
- windows is ok with dual GPU, can have display from both GPU, for simplicity, disable RX 580 from Device Manager
- temperature comparison with single 1080ti GPU installed ~ 5 C, ok for me
- follow the guide to find 1080ti path
- dump DSDT with SSDTtime
- download SSDT-GPU-DISABLE, replace some characters with matching 1080ti path
- compile the SSDT-GPU-DISABLE -> SSDT-GPU-DISABLE.aml and put in the EFI/OC/ACPI at bootable USB
- edit config.plist at bootable USB with text editor to add the SSDT-GPU-DISABLE.aml
- boot with bootable USB, motherboard post by default with 1080ti, after the osx start to boot, it will freeze the 1080ti output, switch monitor input to the ones come from RX580 ( Dell UD2719 do this automatically )
- login to catalina and update EFI partition at the SSD with clover with content from bootable USB again
- restart and boot from the SSD
it works

audio from motherboard audio jack after using the disable GPU ACPI patch
