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.

This text is the general explanation of this category of part (not a claim about one specific model).
