A server would struggle to drive that many ranks directly. The buffer chips on an LRDIMM hide the load, so the server sees a simpler module and can hold more of them in each channel. The trade is a little extra latency and some added power.\u003c\/p\u003e\n\u003cp\u003eDell lists LRDIMM support on the R620 with 8GB, 16GB, 32GB, and 64GB sizes, in single-, dual-, quad-, and octal-rank forms.
