What is LRDIMM Server Memory?
LRDIMM (Load Reduced Dual Inline Memory Module) server memory is used to enable stable server systems with large memory capacities.
While with RDIMM memory, the register handles the address lines to relieve the Northbridge, the LRDIMM technology goes one step further. Here, the iMB (isolated Memory Buffer) takes over the address lines, control signals, and even the actual data lines from the Northbridge of the server system. By consolidating the data lines at the central memory buffer, an LRDIMM places the same load on the server as a comparable 1-rank RDIMM memory module.
In practice, this means that with many servers, only 4 out of 6 memory slots can be occupied with RDIMM memory, but all memory slots can be fully populated with LRDIMM memory. As a result, the maximum memory configuration can usually only be achieved with LRDIMM memory.
LRDIMM memory also includes ECC and Chipkill functions to ensure high server memory security.
Using LRDIMM technology excludes the simultaneous use of other memory technologies such as RDIMM and ECC UDIMM in the server.
