I wonder if anyone can help me. My motherboard is EVGA X99 Classified. There is a M.2 Type 3 connector on board. I bought a Samsung 860 EVO 2TB M.2 SATA SSD. According to the motherboard manual, I have to enable the M.2 Type 3 in the BIOS which I have (by doing so, PCIe slot 5 will be disabled and I have nothing in PCIe 5). But the SSD seems not being detected. I don't see it in the BIOS nor in Windows. I have Window 7 Ultimate Pro 64 bit. However, I did notice that windows 7 has installed the driver after enabling the M.2 Type 3 in the BIOS (after the boot up of course). Have I bought the wrong type of SSD? I have noticed that the SSD has two notches whereas the M.2 Type 3 connector has only one. Any idea? Many thanks in advance for your help.
