LRDIMM

LRDIMM – Load Reduced DIMM memory module. Such DIMMs can have up to eight ranks or blocks of memory. They have a memory buffer instead of a register like RDIMMs (Register DIMMs). The memory buffer is used to consolidate the electrical loads of LRDIMM ranks to a single electrical load on the motherboard, enabling the up to eight ranks on a single DIMM module, and helping configure systems with the largest possible memory capacity. LRDIMMs use more power and have higher latencies compared to the lower capacity RDIMMs. LRDIMM memory chips are used in servers in data centers, cloud computing, and high-performance computers.
