Server DDR4 ECC RDIMM module

This 4 GB registered DIMM runs at 2400 MHz with CL17 latency and 1.20 V operation. It is built for servers and workstations that require error-correcting memory. The 1Rx8 organisation and 288-pin form factor match the Kingston KVR24R17S8/4 specification. Systems needing registered ECC DDR4 can use this module as a direct replacement.

Standard voltage and registered design

Operating at the DDR4 standard 1.20 V keeps power draw low in normal use. The registered buffer reduces electrical load on the memory controller, which helps stability in multi-module configurations. No special cooling is required beyond typical server airflow. The module meets JEDEC electrical specifications for its speed grade.

Replaces non-ECC or slower DDR4 DIMMs

This module upgrades systems that currently run unbuffered non-ECC memory or lower-speed DDR4 where the platform supports registered ECC. The jump is worth it when data integrity and multi-DIMM stability are required for virtualisation, databases or long-running compute tasks. It is not for desktop boards that lack registered ECC support or for builds needing higher capacity per slot.

Questions about this item

How do I install this 288-pin DDR4 RDIMM, and what step do people often miss?

Align the notch on the module with the slot key, press down firmly until both side clips click shut, and ensure the motherboard is set to 1.2V in BIOS for correct DDR4 voltage.

What maintenance or replacement will this ECC RDIMM need over time?

No routine maintenance is required; the module is tested for lifetime reliability and should only be replaced if system diagnostics report correctable or uncorrectable memory errors.

What limit appears first when this CL17 2400MHz module runs under sustained load?

The CAS latency of 17 cycles at 2400MHz sets the timing floor, so sustained throughput is bounded by the rated DDR4-2400 transfer rate and registered buffer overhead.
