4GB DDR3L 1333 ECC RDIMM

This 4GB DDR3L registered ECC module is built for servers and workstations that require error-correcting memory. It operates at 1333MHz with a low 1.35V voltage and uses a 240-pin DIMM form factor. The single-rank 2Rx8 configuration fits systems designed for registered DDR3L memory.

Registered ECC with 2Rx8 organisation

The registered buffer and ECC capability are the deciding factors for compatibility. Only motherboards that support registered DDR3L ECC RDIMMs can use this module; unbuffered or non-ECC platforms will not accept it. The CL9 latency and PC3L-10600 rating are fixed by the module design.

Single 4GB module for light workloads

A single 4GB stick suits entry-level virtualization, file serving or legacy database tasks that stay within a small memory footprint. Workloads that exceed 4GB per channel will require additional modules or higher-capacity RDIMMs to avoid swapping.

Questions about this item

What does the 1333 MHz speed mean when the module is installed in a server?

The module runs at 1333 MHz DDR3L, delivering a PC3L-10600 data rate with CL9 latency and 1.35 V operation.

How does the DDR3L registered ECC interface limit performance in practice?

The registered ECC design adds one clock cycle of buffering and enables single-bit error correction, capping raw bandwidth to the PC3L-10600 spec.

What physical slot and keying does this 240-pin DIMM require?

It fits a standard DDR3 240-pin DIMM socket with the DDR3L low-voltage key notch.
