Help Please! 2nd 960 Pro causes Freeze @EFI mount on Z370 Aorus 7

[nrgsquad]

Hi there,

got an nearly golden Build made of an:
Gigabyte Z370 Aorus Gaming 7
8700K
32GB Crucial Ballistix Elite 3000MHz (4x8)
GeForce 1080Ti
BCM***2CS on an Adapter-Card (BT+WiFi)
2x 960 Pro 512GB
Crucial SSD 275GB SATA M.2
3x HDD
Custom Watercooled

Newest Clover, 10.13.4


I have an big issue with my NVMe´s:

When i have the second one plugged in (Windows drive) in Port 3 (lowest on that Board and made just for PCIe SSD) and i try to mount my EFI Partition in OS X of the Boot NVMe (which is plugged in to the upper Port of the Mainboard) the OS Freezes after 2 seconds and needs a Reset via Button to reboot.

I works like charm, unless i mount my EFI.

I looked in to the Error report and it says something about NVMe (com.apple.****nvme***).

So ithink the error lies here.


Can please anybody help me with that? I can access my EFI when i unplug the 2nd NVMe from the Board, but for Updating Clover or Kext i don´t think it´s good to do this too many times...


Thank you in advance an a nice Day!
