I’m building a high-performance firewall after the Son of the Forbidden Router. Key components include an ASRock Rack W680D4U-2L2T/G5, two Micron 1920GB 7450 Pro U.3 SSDs, and two cables from Micro SATA Cables: https://www.amazon.com/dp/B08HZFGK8N. When I check the BIOS setup, it says, “No NVMe devices detected.” Can you help me troubleshoot? I can’t tell if it’s the motherboard, the drives, or the cables.
The best chance is the BIOS: make sure it allows for PCIe booting. It should so by default, most mainboards do, but best check if that’s really the case.
If that fails, consider an alternative to the cable, as that’s the cheapest to replace: a PCIe to U.2 adapter board. (I know it’s “only” U.2 but that shouldn’t make a difference for an NVMe drive)
HTH!
It’s been a while since you posted this and I had the same issue back in September last year with the same motherboard, two Micron 7450 MAX 800GB and the same cables from Micro SATA Cables. After a bit of back and forth with ASRock Rack support, it turns out that the OCuLink pinout of the cables from Micro SATA Cables isn’t correct for the motherboard. The only cables that are known to work with ASRock Rack motherboards, based on a variety of forum and Reddit posts, are Supermicro CBL-SAST-0956. I just got my SSDs working with these cables last weekend.
I actually had the same problem I had to get pcie cards to get them to work with u.2 drives
