KBlast Posted January 30, 2021 Share Posted January 30, 2021 I am using Asrock EP2C612 WS motherboard with the ASUS Hyper V2 card, 1TB 970 EVO plus in first slot and 2x 480GB NVME in slot 2 and 3. I have the latest BIOS and I have the card in PCIE Slot 1 with PCIE Slot 1 set to x4/x4/x4/x4. Unfortunately only the 1TB card shows up and the others don't. Any ideas on how to solve this?

Vr2Io Posted January 31, 2021 Share Posted January 31, 2021 Pls try rearrange m2 in different slot order. Pls also check does another addon card have share the link with that pcie slot. Bifurction really trouble stuff, many compatible issue. Quote Link to comment
unrateable Posted January 31, 2021 Share Posted January 31, 2021 (edited) re-check PCIE1 Link Width and PCIE Link Speed and maybe disable ACS Control Edited January 31, 2021 by unrateable Quote Link to comment
SeeGee Posted February 16, 2021 Share Posted February 16, 2021 Does your bios support 4x/4x/8x? I had an issue with my hyper m.2 where I had a single nvme, I had to leave it on 16x, when I added a second, I had to use one in slot 1,another in slot 3 and set bios to 8x/8x before it would detect. 4x/4x/4x/4x wouldn't work. I have a third nvme to add, I'll let you know how it goes, but I expect I will need to set it as 4x/4x/8x before it'll detect properly. System specs in Sig. Quote Link to comment
