i7-12700KF - Gigabyte Z790 D DDR4

​

macOS Sonoma 14.3

I rebuilt my system from this post. Currently had failed RAM, but decided to rebuild with a Gigabyte Z790 D DDR4 Motherboard, and a i7-12700KF. Same dGPU (AsRock Radeon RX 6800 XT Phantom Gaming) and different RAM but same speeds.

• i7-12700KF
  • CFG-Lock Disabled in BIOS
  • All E-Cores & P-Cores enabled
  • No custom CPUFriend kext.
    • Only utilizing CPUTopologyRebuild.kext
• 32GB DDR4-3200 RAM
  • Utilizing RestrictEvents.kext for CPU naming, and hiding software RAID drives
• AsRock Radeon RX 6800 XT Phantom Gaming
  • Screens come on slightly faster with this setup, unsure why but currently investigating.
• Audio
  • Realtek ALC897 Codec
• Network
  • Realtek RTL8125B 2.5Gbps PCI Express Ethernet
  • Intel AX210 WiFi 6E PCIe Adapter
    • Utilizing Airportitlwm.kext + IntelBluetoothFirmware.kext + IntelBTPatcher.kext + BlueToolFixup.kext
• Storage Drives
  • Western Digital WN770 1TB PCIe 4.0 M.2 2280 Drive
  • Samsung 970 EVO Pro 512GB PCIe 4.0 M.2 2280 Drive
  • Samsung 860 EVO 1TB SATA
  • Samsung 860 EVO 500GB SATA
  • Samsung 860 EVO 250GB SATA
  • sRAID Setup
    • Western Digital (WD2002FAEX-007BA0) 2TB SATA HDD
    • Toshiba (WD2002FAEX-007BA0) 2TB SATA HDD
• OpenCore
  • Version 0.9.7
  • Secure Boot is currently in progress and all OpenCore binaries are already signed with the signature being used for the BIOS
  • Currently utilizing CustomSMBIOSGuid + UpdateSMBIOSMode as some Gigabyte software checks SMBIOS data and will not work if its not a compatible Gigabyte product.

Performance is actually pretty on point when compared to Windows. Roughly a 6% decrease in single core performance and roughly 3% multi-core performance decrease overall. Not bad considering the emulation (VirtualSMC, and other kexts that mimic mac hardware) overhead that normally takes a 2-3% overall decrease in performance.

What Works

1. CPU Power Management
   1. So far E-Core & P-core scheduling appears to be working
2. dGPU with Full DRM functionality
3. Ethernet
4. WiFi
5. UPS Battery Backup
6. USB Ports

What Does not Work

1. iGPU as there is none
2. Continuity
3. Sleep
   1. Sleep works once, then fails. This is so far due to the Z790 updated BIOS for Rocket Lake and newer CPUs
   2. Since I cannot downgrade the BIOS, this is non-fixable in the current standpoint but it's still being investigated

Overall, another successful build that honestly am more impressed.
