Server Memory Module

The RIMLANCE RRD21300S8C4 is a 4GB DDR4 2666MHz ECC Registered RDIMM built for servers and workstations that require error-correcting memory. It uses a 288-pin form factor and operates at 1.2V with a CAS latency of 19. This single-rank 1Rx8 module suits IT professionals upgrading compatible DDR4 platforms.

DDR4 2666 Interface Limits

The module runs at the PC4-21300 standard, so its maximum bandwidth is fixed by the DDR4 2666 specification. Registered buffering adds one clock cycle of latency compared to unbuffered DIMMs, which affects timing-sensitive workloads. ECC functionality requires a motherboard and CPU that actively support error correction; without that support the extra parity bits provide no benefit.

Capacity and Headroom

Four gigabytes provides a minimal footprint for lightweight virtual machines, network appliances or test environments. The single 1Rx8 rank leaves DIMM slots open for future expansion up to the platform's maximum supported capacity. Workloads such as large databases, heavy virtualization or in-memory analytics will exceed this module's capacity quickly.

Preguntas sobre este artículo

Is the 4 GB module the right choice if I need a single stick for a server upgrade?

This module provides 4 GB in a single 1Rx8 registered DIMM, so it fits one slot and adds ECC protection for data integrity.

What does the 2666 MHz rating deliver once the DIMM is installed in a compatible system?

The module runs at DDR4 2666 with CL19 latency, giving a peak bandwidth of PC4 21300 for server workloads.

Will the 288-pin DDR4 registered interface work in my DDR4 server motherboard?

The 288-pin RDIMM uses the standard DDR4 registered interface at 1.2 V and requires a motherboard that supports registered ECC memory.
