I have an ASUS ROG STRIX B450-F motherboard with two NVMEs one of which works well and detects a disk installed in it. I tried to install another ssd on the board NVME is not detected in the BIOS in the bottom connection but only at the top,the problem is repeated with both disks and only at the bottom. The simple question is is the problem in the board? Was purchased about a month ago or problem in BIOS settings? I updated the BIOS and everything possible from the ASUS website and it didn't help..I would love to get an answer soon, thanks.
