Troubleshooting - Asus X470-i M.2 Not Recognized

[wanderica]

I just built a new Ryzen 2700X SFF watercooled build using the (very) recently released Asus X470-I motherboard, and I have pretty large issue that I can't seem to fix. I transplanted my Samsung 960 Evo NVMe drive to the new rig along with my other 2 drives, but it isn't recognized in Windows or in the BIOS. Some googling seems to point to Asus sharing M.2 slots with SATA ports 1 and 2, but removing all other drives (1 SATA SSD, and 1 SATA HDD) doesn't work either.

The other 2 work perfectly, and I was able to install Windows on my 256 GB SSD. Disk Manager doesn't show the M.2 either. Some folks in the past have had issues with this on Asus boards, but I can't seem to find the answer. I still need to try moving it to another board to test on a known working m.2 slot, but I need to cobble together my old rig to test. I didn't think to test it as it was known working when removed. I'm hoping someone here here has had success with BIOS settings on Asus boards discovering M.2 drives. I would really like to avoid disassembling this build if I can. It took all weekend to build, and RMAs are troublesome at the best of times.

Try clearing CMOS, if that doesn't work try re-seating the drive, make sure it is pushed all the way into the connector.

Thanks for the reply. Both done and no dice. I even tried cleaning the connectors. I'm working on tossing it back in my other PC at the moment just to rule out a bad drive. I sort of hope that's it as it's still under warranty. I'm afraid it may mean RMAing the board otherwise.

Looks like it isn't the drive. It could still be the slot, but I'm not 100% convinced it isn't a setting in the BIOS. Is it strange that an M.2 slot would be completely dead right out of the box?

Looks like it was the slot after all. I managed to cram my crazy man fingers behind a mITX mobo in a Nano S and get the drive into the rear slot. I've had no issues since. Thanks again.

You could try the other slot just to see if it works. It's not ideal though since it will make your x16 PCIe run in x8 mode.

edit: I see you just posted while I was typing and that the other slot indeed works.

Yeah I'm not happy about that, and I'll likely RMA the board. After all, for $200, it can damn well work as advertised. For the immediate future though, it at least solves my issue.

Gen 3 x8 mode doesn't seem to make much of a difference anyway, from what I can tell, and since it's only temporary, no harm done.
