Product information

Description

HPE Registered RDIMM 16GB DDR4-2933 CAS21 Dual Rank x8 is a server memory module designed for enterprise environments requiring reliable performance and capacity. This single-module kit (1 x 16 GB) operates at 2933 MHz with a 1.2 V supply and includes ECC to support data integrity in servers and workstations. The module is tailored for deployments where higher memory throughput and efficient power use are important, such as virtualization hosts and data-center systems.

Advantages

This RDIMM delivers a balance of performance, capacity, and power efficiency. It runs at top throughput for DDR4-2933 and supports error-correcting code (ECC) for improved reliability in continuous-operation environments. The module’s dual-rank x8 design helps increase usable capacity and compatibility with server platforms that support registered memory, while the 1.2 V operating voltage contributes to lower power consumption compared with higher-voltage variants.

Suitable for

Server memory upgrades
Virtualization hosts and hyperconverged infrastructure
Data center and enterprise workloads requiring ECC
Workstations that accept RDIMM modules

When it may not be suitable

This registered RDIMM is intended for systems that support RDIMM modules and ECC. It is not suitable for consumer desktops or laptops that require unbuffered UDIMM memory. Systems that do not support DDR4-2933 speeds, RDIMM form factor, or ECC may not be able to use this module or may fall back to lower speeds or reduced functionality.

Key specifications

Capacity: 16 GB (single module)
Memory type: DDR4
Speed: 2933 MHz (DDR4-2933)
Configuration: Dual rank x8
Form factor: Registered DIMM (RDIMM)
CAS latency: 21
Voltage: 1.2 V
Error correction: ECC (registered)
Weight: 0.045 kg

How to use

Install the module into a compatible server or workstation memory slot following the system manufacturer’s instructions. Ensure the system supports RDIMM modules, DDR4-2933 speed, and ECC. For best results, populate memory channels according to the server’s recommended configuration and verify BIOS/firmware settings to enable the appropriate speed and ECC support. After installation, run system diagnostics to confirm the module is recognized and functioning correctly.

What to consider before purchase

Confirm motherboard or server compatibility with RDIMM and registered ECC memory
Verify support for DDR4-2933 speeds or understand potential downclocking to lower speeds
Check whether the system firmware supports dual-rank x8 modules
Consider matching existing memory ranks, speeds, and voltage for multi-module configurations

Usage recommendations

Use this HPE 16GB Registered RDIMM in servers and workstations that explicitly list support for RDIMM DDR4 modules with ECC and DDR4-2933 speeds; populate memory channels symmetrically and keep firmware up to date to ensure optimal compatibility and stability.
