The M.2 SSD isn't detected by BIOS or Windows.
The M.2 SSD isn't detected by BIOS or Windows.
Confirming the setup: the M.2 device is securely placed in its designated location.
Board specifications: ROG Strix B550-F Gaming motherboard. CPU: Ryzen 7 5800x. Graphics: Nvidia RTX 3070 ti (Asus TUF). RAM: G.skill Trident Z RGB 2x16GB (DDR4). Storage: Seagate BarraCuda 4TB HDD, SSD: Samsung 990 Pro PCIe 4.0 M.2 (1TB). Cooler: Kraken Z53. Case: Corsair iCUE 4000X mid-tower ATX. Power supply: ASUS ROG Thor 850W 80+ Platinum. Mounting note: Position is upper left M.2 slot above GPU, fully installed.
Review the instructions, as certain motherboards disable some SATA ports when you add a M.2 drive in the second slot. The BIOS may opt to retain the hard drive and turn off the M.2 port. To resolve this, relocate the SATA cable to a different port that isn’t shared with the M.2 connector. Other issues could involve compatibility—some M.2 connectors support only PCIe (NVMe), while others also support SATA. If your SSD is SATA-only, it won’t be recognized and won’t function in a PCIe-only M.2 slot. The 990 Pro is clearly NVMe and should be placed in the nearest M.2 slot closest to the CPU socket. According to the ASUS guide, when the M.2_2 slot is filled, SATA6G_5/6 ports will be turned off.
The nearest M.2 port to the CPU socket is M.2_1, which draws from the CPU PCIe lanes—ideal for a single M.2 device. The following M.2 can fit into the M.2_2 slot, though it might experience a minor performance reduction since it uses chipset lanes shared with other components like I/O, audio, and Ethernet.
Ensure the SSD is set up correctly – it fits into the connector when held at a 30-45 degree angle, and after insertion, lightly press it down until the screw secures it.
Thank you, please review both options and let me know when you're ready!
Thank you, I’ll make sure to test both options and come back once I’ve tried them.
