QL1M is a well known 16 core. supported by X11 UP Family (X11SPi-TF, X11SPL-F, X11SPM-F/TF/TPF, and all other UP models)Xeon Gold QL1M. I was wondering if it could work with the X11SPA, but any workstation oriented lga3647 would do.
i had this recently running on a X11SPM-F bios 2.x
you should know: supermicro has removed SKL ES support from bios in rev. 3.x and up because of new cascade lake microcodes.
there is no bios 2.x available for the X11SPA because it is a very new board(2019).
some seller provide a modded bios 3.0 with SKL ES support for selected boards, you have to ask the seller.
