Assistance with a second PCIe slot
Assistance with a second PCIe slot
You encountered a setup issue because you placed the NVMe adapter in an unintended PCIe lane. It seems the second PCIe slot is reserved for GPUs, so using both M.2 NVMe lanes blocks it. There’s no built-in toggle to switch it back on automatically—once the lane is occupied, it stays disabled until another slot becomes free. You’d need to either remove the GPU from that slot or use a different slot with available lanes.
It looks like you're expressing disappointment about the MSI MAG B550M Mortar Max Wi-fi. You might consider getting a SATA adapter as an alternative.
