64GB RDIMM & LRDIMM deals — big sticks, fewer slots

64GB sticks are how you reach half a terabyte without exotic hardware. In DDR4 they come both registered (RDIMM) and load-reduced (LRDIMM) — mind that the two can't mix in the same system — and the LRDIMMs are often the cheaper per GB of the pair.
