Opencore runs unstable booting OS from NVMe(SSD works great)

[dasca.thea]

Hi everyone,

I have run into a frustrating problem here.

My hardware:
MSI x399 Meg Creation
2990WX
64GB ram @2933Mhz
Radeon 7
Sata: Samsung 130GB SSD
M.2: Samsung 970 Pro 1TB

PCIe:

intel x550T2

Blackmagicdecklink 4K

catalina 10.15.4(both 10.15.3 works the same way)

 

Using OC 0.5.6: I have successful installed OSX catalina onto my SATA SSD. It works flawlessly.

 

But with NVMe drive, there are a lot of problems.

I had to take out all PCI card during the installation. After that, the OS runs fine, but every time I reboot, I get kernel panic "Error Loading kernel 0x1" most of the time. Sometimes powering it down and turn back on works fine. sometimes I have to rebuild Cache from recovery partition.

It will only work when I use SMBios MacPro6,1 and my RAM speed has to be 2133Mhz(default)

 

I am guessing it has something to do with PCI lane that is managed by the chipset? right now I manual set PCI gen and PCI lane allocation in the Bios.

 

Can someone please help?
