February 14, 20224 yr So, feel free to tell me if there is a better place for me to post this question. I have just built myself a new 12600k system, currently housing 14 HDDs (using SATA ports 0-5 and 8 ports on a SilverStone ECS04 SAS Controller), and 2 m.2 drives. Everything so far seems to be working well, at least after I updated to the f6 bios, as before none of my m.2 drives were showing in the BIOS. My PCIe lanes are populated like this: m.2 1TB drive in M2a_CPU (top slot) HBA Card in Top 16x slot M2P_SB (mid slot) unpopulated m.2 500GB drive in M2Q_SB (bottom m.2 slot) I tried to populate the 2nd 16x PCIe port (at 4x) with an IBM 46m0997 sas expander, as well as a couple of other random PCIe cards I had lying around, and the system was unable to post with anything in the slot. Anyone have any ideas on why I cant get a post? or alternatively, would a m.2 to 4x PCIe adaptor work in the spare m.2 slot? Edited February 14, 20224 yr by Die_piggy
February 14, 20224 yr What says the manual? Gigabyte isn't the best choise for a sys like unraid... sorry for that... They always have problems with various components and the BIOS itself... Edited February 14, 20224 yr by Zonediver

February 14, 20224 yr Author They are both Crucial P2's. Just for clarity incase I didnt say it right, the m.2 drives are available and working, its when I put a 2nd pcie card in that I fail to post

February 15, 20224 yr Author honestly, no I havent spent much time on it yet, I had a different issue which caused 4 drives to become "unmountable: Unsupported partition Layout" which I am working through right now from memory, the only thing I saw which could fit was a bifurcation setting
February 21, 20224 yr Author for anyone randomly searching, enabling 8x/8x bifeyrcation did the trick, everything is working perfectly now
