Question I have an X9DAI and for some reason my NVMe controller is not being seen. In PCI/PCIe/PNP settings in the motherboard bios. I've set the bifurcation to 4x4x4x4 nothing is seen, but I can only see one of my NVMe's when the slot is set to x16. Answer Unfortunately, we have not tested NVMe HBAs on the X9DAI, and the bifurcation meant for our risers. riser link - https://www.supermicro.com/support/resources/Riser.cfm Was this FAQ helpful?
