Zenith II Extreme Alpha - Dimm.2 Module issue

[roungchen]

So I recently finished building my pc and I notice issue relating to Dimm.2. I installed two nvme on Dimm.2 module. Time to time when windows booted. Either both are not accessible or one of them is not accessible. Both appear in the windows explorer with drive letter. If I restart again, I have access it again. It is dimm.2 issue or nvme issue.
