Hello, i‘ve a RX580 in the first PCIe Slot (runs with x16 and should stay as it is), a Fenvi in the short x1 PCIe Slot and three NVMe SSDs (all in the M.2 Slots). Now the NVMe SSD in the lowest Slot only runs with x2. Is there a way to get all SSDs to work with x4?

Unfortunately the bottom M.2 slot shares bandwidth with the bottom PCIe slot. When both are occupied, each operates at x2. There is no way to change this.

Thank you for your answer. The bottom PCIe Slot is empty in my System.

@CaseySJ Maaan that was a rough week...
I can't believe I'm looking and the Catalina backdrop on my Hackintosh...
It would have been imposssible without your help. I'm so thankful!

Did you figure out what was off?
Did you need to disable anything Wifi/BT to geit it working? I have neither...

Now, I wasn't expecting for it to work and the installation caught me off guard. I didn't read the guide to go through the Install and named the SSD 'SSD' instead of Catalina. Could taht be related to Wifi not working?

For Big Sur (kernel 20.x.x) we spoof the CPU ID, but this is not generally needed for Catalina. Some systems, however, won't boot without it so I changed the MinKernel to 19.0.0 (Catalina). This means Fake CPU ID will be applied to Catalina and all subsequent versions of macOS.

WiFi/BT settings were not changed. Naming your disk "SSD" is also perfectly fine.

Understood. Looking at the owner's manual I don't see any specific mention of PCIe lane allocation for the 3 NVMe M.2 slots. I would be surprised if all three slots operated at x4 due to limitations in total number of PCH lanes. So I believe what you are seeing is in fact correct.

You may of course submit a ticket to Gigabyte Tech Support asking for clarification.

Ok, i‘ve removed the CNVi WIFI Bluetooth card and now all NVMe SSDs run with x4.

That was a stroke of genius! I never thought of that...

hello all! I have a new build I am setting up hardware details are attached below. Well I am having troubles booting from a hard drive created from UniBeast. Also have tried following using the step provided but I could not boot from the USB drive after following the steps from point 8.. Couldn't even get into the boot loader using OpenCore method. Not sure if I made a mistake or I am not following the guide. Any help or hints would be appreciated.

Hello @jaygunz,

Some questions:
  • Are you installing Catalina or Big Sur?
  • Are you using OpenCore 0.6.5 latest version that I posted earlier today at the bottom of Post #1?
