So if RDIMM ends up not an option (hopefully not, I really don’t want to go that big without ECC, and I have easy access only to that RDIMM with ECC here), I have as a second option here M378A2K43CB1-CRCD0, which is the next revision of the M378A2K43BB1-CRC they have listed on that page. Good.
BTW, bundled DIMM in my case was M378A5644EB0-V03.
I confirm that the above MTA18ADF2G72AZ-2G3B1ZK (dual-ranked 16GB Micron with ECC) works fine. It could also be found as a Supermicro branded DIMM (which was my case), but the original Micron part number was preserved on the DIMM.

I searched on google but I could not find any sources of it, nor I found it on Newegg. Could you please recommend a source?
Also, does anyone know if it’s possible to get from any source the board without any accessory (PSU, ram module, etc)?
If you zoom at the left side of the DIMM you’ll notice the original Micron designation.
Re sources of Macchiatobin — that’s a tough question; SolidRun are in super-long lead times currently; I recently tried ordering from Avnet (1st vendor on the ‘Order now’ page) but they refuse to ship to non-businesses (which was my case). So let us know if you find another source.
