Parts List

• CPU: Intel i9 9900K
• Motherboard: Gigabyte Z390 DESIGNARE
• GPU: Sapphire Radeon RX Vega 64 8GB
• RAM: 2x 16GB Kingston HyperX 2666MHz
• Case: Fractal Design Define R6
• Extras: Blackmagic Decklink 4K Extreme 12G, NZXT Internal USB hub

Working

• All case and motherboard USB 2 and 3 ports
• iGPU (I think)
• Onboard audio
• Both onboard Thunderbolt 3/USB 3.1 (not tested yet, hotswapping isn't supposed to work)
• Internal case USB hub
• 5 SATA HDDs + 1 NVMe

Not working

• Intel CNVi WiFi+Bluetooth card (could switch out for a BCM94331CD I have, but I don't really need WiFi+Bluetooth in macOS)
• Occasional "couldn't allocate runtime area" problem on boot - solved by restarting the computer (looking into eliminating this altogether)
• "About This Mac" Unknown CPU (looking into fixing this not just cosmetically)

Notes

I initially was going to do a build using a Titan Ridge AIC on a Z390 UD board, but I read about the VRMs on the UD were barely passable for supporting the 9900K, so I decided to upgrade the motherboard. I still own both of those and do intend trying to see if I can get the card to work with the Z390 chipset along with hotswap once I save up for some more RAM and another CPU.

​

While I haven't been seeing any places this build has been falling short, I am a little concerned that my CPU shows up in IORegistryExplorer under "PR" instead of "CPU". If anyone has any information about this, sharing it would be much appreciated!

Thank you to all previous OPs who've documented their work and consequently made this build almost problem-free!
