If you encounter this problem, please refer to your motherboard's user manual or the manufacturer's website. Motherboards vary by model and brand. The type and quantity of I/O ports are not the same; therefore, when a SATA or NVMe M.2 SSD is inserted into the slot, it may be affected by I/O. The sharing of channels by the ports results in a limited number of channels supported by the chipset, rendering some 7pin SATA sockets unusable.
Firstly check the make and specifications of your motherboard on the manufacturers website to see if it has M.2 slots that support PCIe 4x4. If there are two M.2 PCIe 4x4 slots, you can use the direct link to the CPU terminal (center Processor) M.2 socket for better performance.
If you have an M.2. 2280 SSD, you can find installation instructions here.
