@ruizscar I guess the Emdoor Mainboards until now only can handle SATA M.2 SSDs. That the NVMe mechanically fits, is in your case unimportant. SATA M.2 SSDs have a B+M Key; an NVMe mostly a M-Key only. So the NVME SSD with M-Key fits in the slot prepared for two keys; but it is dependant which protocoll is implemented. In the Emdoor Mainboards it is mostly the SATA protocol only. So you should send your NVME M.2 back to the retailer, and swap it for a SATA model. Cheers, daddle
