Server memory for ECC workloads

This 8 GB DDR4 module is built as a registered DIMM with error-correcting code, targeting servers and workstations that require data-integrity protection. It replaces the Crucial CT8G4RFS424A part number and fits systems that accept 288-pin DDR4 RDIMMs at 2400 MHz.

Steady throughput at rated speed

Running at PC4-19200 with CL17 latency and 1.20 V, the module delivers consistent bandwidth during prolonged compute tasks rather than short bursts. The single-rank 1Rx4 organisation helps keep electrical loading predictable across populated slots.

Registered design for dense configurations

The registered buffer reduces signal load on the memory controller, allowing larger populations of modules in multi-socket platforms. Major-brand DRAM chips and factory testing aim to minimise early-life failures in always-on environments.

Questions about this item

How much power does this 1.20 V DDR4 2400 registered ECC module draw when the server runs continuously?

At the standard DDR4 voltage of 1.20 V the module draws minimal power; registered buffering adds slight overhead but total consumption stays low for an 8 GB stick.

What motherboard slot and chipset support are required for this 288-pin RDIMM to function?

You need a server or workstation board with DDR4 RDIMM slots (288-pin) and a chipset that accepts registered ECC memory; consumer boards without RDIMM support will not work.

Can this CL17 1Rx4 registered DIMM work alongside other DDR4 2400 modules already installed?

Mixing is possible if the other modules are also DDR4 2400 registered ECC; matching rank, voltage and CAS latency helps stability, but the system will run at the slowest common settings.
