Hello, I'm new, I am getting an error when I try to make a new post about the issue I'm having here.
I have a Samsung 990 Pro 4TB SSD that is not detecting on any of the m.2 slots on my new ASRock X870E Taichi motherboard. I have double checked, the drive DOES work, I have a USB m.2 enclosure, as well as a pcie m.2 card, and it detects in both of those and works. I know the Samsung 4TB 990 Pro is not on the QVL for the motherboard (for some reason I don't understand given the popularity of both the drive and the motherboard), but I'm hoping that this is something that is fixable to have it work in one of the motherboard's m.2 slots, since running the pcie m.2 card lowers the bandwidth on the GPU slot to x8 5.0, and using the USB m.2 enclosure limits the drive speed to 1GB/s.
Please advise, thank you, if I should contact customer support of Asrock directly let me know.
