Description
RDIMM memory (Registered)
An RDIMM is an ECC memory module with a register that buffers the address and command signals to reduce the electrical load on the memory controller.
RDIMM is the most common server memory type and has a good balance between capacity, latency and price.
ECC error correction prevents data corruption and system halts, and more modules can be installed per channel.
