Hello I have two identical Intel x710 cards, two x16 risers, and an m90q gen 3 and m90q gen 4, both with updated BIOS. The m90q gen 4 works correctly with the x16 riser and the x710-da2. The m90q gen 3 can’t get past the Lenovo boot letters. Updated BIOS (the risers and x710s have been swapped, and the problem persists).
Ref riser is 5C50W00933 lenovo genuine
What am I missing?
Looking into maybe adding an X710 to mine currently, and ran across your post. I ran across a post on the STH forums (I just created an account, so I can’t post a link - just search for the thread “Lenovo Thinkcentre/ThinkStation Tiny (Project TinyMiniMicro) Reference Thread”) that may be of help. Take a look at the “Riser Cards” section, and see if that gets you anywhere (there’s reference to a workaround for an issue with some older PCIe cards that involves shorting some pins)
