Is is possible to mix Rdimm 2Rx8 with 2Rx4?- supermicro X10SRA-F

[ebroock]

I have 4 x16GB 2Rx8 PC4-2400 in my workstation and would like to add more ram,
however, I'm finding with good prices only 32GB 2Rx4 PC4-2400.

I can not find enough info if they can be mixed. I would guess using them isolated in banks A and B.

Is someone with hands-on experience in this situation?

mixing of x8 and x4 organized modules is alowed in X11 lga3647 systems.
but the matching memory conf.guide for X10 does not mention anything about mixing bit width.
