4GB DDR4 2400 ECC RDIMM for Servers

This 4GB registered ECC module targets administrators upgrading or repairing DDR4 server and workstation platforms. It delivers 2400 MHz speed with CL17 latency at the standard 1.20V operating voltage. The 1Rx8 organisation uses major-brand chips on a 288-pin DIMM. It serves environments that require error correction and registered signalling for stable operation.

Straightforward DIMM Installation

Insert the module into a compatible DDR4 RDIMM slot until the retention clips engage; the key notch prevents incorrect orientation. No extra cables, drivers or firmware steps are required. The main risk is mixing registered ECC DIMMs with unbuffered or non-ECC memory, which prevents the system from posting. Always confirm the platform supports registered ECC before purchasing.

4GB Capacity for Light Workloads

The single 4GB rank handles basic virtualisation hosts, entry-level database nodes and memory-limited legacy applications. Headroom disappears quickly with multiple VMs, large in-memory caches or modern container orchestration. Systems needing more than a few gigabytes per channel will require higher-density modules or additional populated slots.
