R250 Critical Memory error
I have two R250 servers each with 2x16GB DDR4 2400MHz PC4-19200 Unbuffered ECC 1.2V CL17 2Rx8 Dual Rank 288 Pin UDIMM each. I have purchased more 16gb ram and it is on the way. In the mean time I combined all four of these UDIMMs into one machine and got the following error.
PST0193 BIOS POST memory test failed.
I tried reseating the ram twice, but still get the error. I tried them in the other machine with the same result.
I put them back in separate machines, 32 each and they work fine.
Is there something that I have to do first to be able to do this?

Can you share the part# of the DIMM currently you have? Are these came with the server or you installed separately. As Charles mentioned dual rank 16GB memory is not supported on R250
