RIMLANCE RRD23400DD4C128 128GB DDR4 2933 CL21 ECC Registered RDIMM

High-capacity DDR4 registered ECC module

The RIMLANCE RRD23400DD4C128 is a single 128 GB DDR4 2933 MHz registered DIMM with ECC and CL21 latency. It targets administrators upgrading DDR4 servers and workstations that require maximum density per slot. The module uses major-brand DRAM chips and is tested for stability in demanding environments. Buyers needing non-ECC or unbuffered memory for consumer platforms cannot use this product.

One stick delivers 128 GB at PC4-23400

This 288-pin RDIMM provides 128 GB of capacity in a 2S2RX4 organisation, running at 1.2 V. It comfortably handles large in-memory databases, virtualisation hosts and AI model workloads that benefit from high per-module density. Systems limited to lower maximum module sizes or slower DDR4 speeds will not be able to utilise the full capacity or rated frequency.

Registered design and ECC aid signal integrity

The registered buffer reduces electrical load on the memory controller, supporting stable operation at the rated 2933 MT/s in multi-DIMM configurations. ECC corrects single-bit errors to maintain data integrity during sustained workloads. The 1.2 V operating voltage aligns with standard DDR4 server power budgets. Modules requiring active cooling or higher voltages fall outside this specification.
