z690m Aorus Elite AX DDR4

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?

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...

What type of m.2 drives? looks like only pci supported not m.2 sata

[Die_piggy]

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

Have you looked in the bios for pci options for card slot?

[Die_piggy]

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

for anyone randomly searching, enabling 8x/8x bifeyrcation did the trick, everything is working perfectly now

it means system can run both pcie full size slots as x8 each?
