Short for load-reduced dual inline memory module, LRDIMM memory chips are used in server settings, like data centers and cloud computing, as well as in high-performance computers. LRDIMM features a memory buffer instead of a register like RDIMMs. This feature allows it to increase the speed of the memory, reduce the load on a server's memory bus, and help to reduce power consumption.
LRDIMM chips are compatible with DDR3 DIMM memory sockets on motherboards. They cost considerably more than RDIMM chips, running upwards of $400-$500 for 8 GB of RAM, but the performance is much better for memory-intensive applications.
