I purchased two micron 7450 NVMe drives for my two virtualization hosts- one Pro and one Max.
- Micron 7450 MAX 800 GB
- Micron 7450 PRO 960 GB
I have two hosts both with Z590 chipsets and are gigabyte (ITX form factor)
- GIGABYTE Z590I AORUS Ultra
- GIGABYTE Z590I Vision D
Both of these motherboards have PCIe4 on the m2 slot on the front (connected via the CPU) and PCIe3 on the back (connected via the chipset).
When I have the Micron NVMe drives in the PCIe4 slot on the front they both do not shut down all the way. The machine runs through the shutdown process, the display goes out and all the lights on the motherboard go off however the power LED and the fans in the system including the CPU fan stay on (forever) until I hold down the power button. This happens with both motherboards and both Micron NVMe drives.
Workaround: Put the micron drives on the rear NVMe slot (PCIe3 connected via chipset)
Has anyone ever seen anything like this? I know these are enterprise drives and not really meant for consumer hardware. They have power loss protection so I’m thinking something in these drives are causing the system not to shut down when connected to the PCIe that is connected to the CPU?
Things I have tried:
- BIOS was updated to latest on both
- Micron NVMe firmware is newest
- Played with power settings in BIOS
Another interesting thing is rebooting- It works perfectly fine with the Micron NVMe in the front slot and the system actually switches off momentarily- power LED goes off and you can hear everything switch off and come back on.
Any help is appreciated! It’s not the end of the world having these in the PCIe3 slot but would like to take advantage of the PCIe4 drive speed!
