I went to add 2 sticks of 8gb DDR3L-1600 RDIMM 1.35V CL11 via crucial to my R710 and it wouldn't boot. I realized the 4 x 2gb ram I already have is UDIMM and I can't mix so I took them out thinking I can still go to 16gb on the RDIMM. Now during post I get a message saying Advanced ECC mode can't be used with this memory configuration. Does Advanced ECC require a different RDIMM or do I need more slots populated or is it something else?
