Hey I had the exact same problem on my Hackintosh with the Corsair Vengeance LPX DDR4@3000MHz.
The solution is as follows
- Open the config.plist in a text editor (Atom, Sublime Text or similar)
- Edit the size of the memories to 16384 MB each
- Save the file and close the editor
- Open Clover configurator and load the config.plist
- Under the SMBIOS tab make sure that the parameters are
all filled in
- Slot: 0 and 2 (VERY important)
- Size: 16384
- Frequency: Since mine are 3000 i used 2600 that is the maximum I have available in the dropdown (will test with 3000 changing he config.plist directly)
- Vendor: Corsair
- Part: check online or make one up
- Serial:<make a random 12 characters string up>
- Type: DDR 4
- Make sure Channels is set to
Dual Channel and slot count is set to
4
- Save changes (File -> Save)
- Reboot
Find the screenshot attached as an example of my config
