T340 memory spec

Hello Everyone

I have a question that I am sure must have come up before, but I cannot seem to find a clear answer to.

I have a Dell T340 where I would like to add memory.  But for the life of me I cannot clearly confirm whether it can take rdimm ecc memory.  Some of the Dell documentation indicates udimm only, and some seem to indicate that the T340 can take rdimm modules too, for example https://i.dell.com/sites/csdocuments/Product_Docs/en/dell-emc-poweredge-t340-spec-sheet.pdf

Anyone with experience on this front?

Thank you in advance
