darrenyorston Posted January 16, 2019 Share Posted January 16, 2019 I am in the process of building myself a new system. A Gigabyte x399 Aorus Xtreme MB, AMD Threadripper 2950X, 64GB ECC memory plus some other junk in Case Labs SM8 Merlin case. I have a query about the motherboard M.2 drives. At the moment only one M.2 drive shows up in Unraid. I was hoping to utilise two M.2 drives as cache. Each of my drives are good. I can swap them between slots and unraid will see different drives. However, when I have two drives installed only one is available. Do I have to raid them in BIOS first? Quote Link to comment

darrenyorston Posted January 17, 2019 Author Share Posted January 17, 2019 Im beginning to think its a motherboard fault. Both M.2 drives work in the centre M.2 port. I am able to access them in unRaid as well as a Fedora which I installed onto a spare SSD. However, neither of the drives work in the other two M.2 ports. Quote Link to comment
JorgeB Posted January 17, 2019 Share Posted January 17, 2019 You're using SATA M.2 devices, some boards can't use more than one SATA M.2 device, they can with NVMe devices, but according to the specs that board does accept SATA or NVMe on all 3 slots, so possibly a board problem.

darrenyorston Posted January 24, 2019 Author Share Posted January 24, 2019 Resolved. Only the centre slot works with M.2 SSDs. To utilise the outer slots requires NVMe M.2 drives. The board will work with an M.2 SSD in the centre and an NVME M.2 drive in any of the others but not in any other config. So if you want multiple M.2 drives on the x399 Aorus Xtreme they have to be NVMe, regardless of what the specs say/dont say. Quote Link to comment

I have two M.2 SSDs, one is NMVe and the other one is SATA. Initially I had the NMVe drive (my boot drive) in the middle (M2P) connector and the SATA drive in the top (M2M) connector. This worked fine with BIOS versions F3 and F4, but not in F5 or its the later variants (F5c, F5c_n, F5g, F5g_n). In all the F5 BIOS variants the NVMe SSD was still detected, but the M.2 SATA SSD was not. Swapping the locations of the drives, with the SATA in the middle (M2P) connector and the NVMe in the top (M2M) connector, has both drives being detected with the newer F5 BIOS variants. Thanks again for your help. Edited June 3, 2019 by Qrash Quote Link to comment
polabs1 Posted June 4, 2019 Share Posted June 4, 2019 If you have two NVME drives, do they HAVE to go into slots 1 and 3? I have been having problems getting 2x NVME drives to show up. Actually it's just one drive causing the issue because it has no partitions but the drive is perfectly healthy. Quote Link to comment
bastl Posted June 4, 2019 Share Posted June 4, 2019 On some boards populating the U.2 slot if available dissables one of the M.2 slots. Same for SATA. Some boards share sata ports with one of the NVME slots. Another thing to mentioned some manufactures share the PCIE slots with one of the M.2 slots. Best is to check your manual to see which ports are shared and what the limitions are if you populate all connections. Quote Link to comment
Qrash Posted July 14, 2019 Share Posted July 14, 2019 (edited) FYI BIOS F5i is now posted for download on the X399 Aorus Xtreme website: www.gigabyte.com/Motherboard/X399-AORUS-XTREME-rev-10/support#support-dl-bios The BIOS is dated 2019/05/08 (08-MAY-2019) which is earlier than when it was sent to another owner as a beta BIOS to solve the detection of mixed (NVMe and SATA) M.2 SSDs, especially when there is more than 1 SATA M.2 SSD.
