I've found that OEM cards sometimes do not work correctly or at all. I suspect that the thorough testing LSI does for compatibility with a variety of vendors is not done by Supermicro, Dell, IBM, etc. on their OEM versions of the cards.
As an example, I have a bunch of X9DBU systems I support that are incompatible with PERC H700 cards if the H700's BIOS firmware is the latest revision. If you step the BIOS back to the 2015 version, it works just fine. Earlier versions of the H700 BIOS firmware also work fine with any Supermicro BIOS version.
