Engineer's Note

This 64GB DDR4-2933 RDIMM with ECC and registered signal type is engineered for enterprise servers and high-end workstations, ideally suited for memory-intensive workloads such as virtualization, in-memory databases, and mission-critical applications that demand uncompromising data integrity. Its quad-rank x4 organization enables higher density configurations while the registered architecture and CL21 latency deliver stable, reliable signaling across multiple DIMM channels under heavy load.

Technical Specs & Insights

1. The 64 GB capacity per module enables dense memory configurations in virtualized servers, allowing far more VMs per host without compromising performance.
2. ECC protection detects and corrects single-bit errors in real time, preserving data integrity for critical enterprise workloads like financial transactions and database processing.
3. Registered signal architecture buffers command and address lines, enabling stable operation across massive memory populations while maintaining signal integrity in multi-slot server boards.
4. A 2933 MHz clock rate delivers high sustained bandwidth, accelerating in-memory analytics, AI inference, and large-scale caching operations under constant load.
5. Quad Rank organization maximizes capacity per channel and leverages rank interleaving, improving throughput for memory-intensive virtualization and containerized environments.

Why These Specs Matter

As a registered server memory module, the HMAA8GR7AJR4N-WMT4AD redefines reliability for mission‑critical infrastructure. Its 64 GB capacity built on a quad‑rank x4 design lets you populate fewer DIMM slots while still achieving the enormous memory footprint required by dense virtualization clusters. This means you can run significantly more virtual machines per host without sacrificing performance, because the quad‑rank interleaving effectively pipelines memory requests and boosts sustained bandwidth under heavy multi‑tenant workloads.

Equally vital is the combination of ECC and registered signal buffering. Cosmic ray‑induced bit flips are not a theoretical concern in a 24/7 database environment—one uncorrected error in an in‑memory database like SAP HANA or Redis can corrupt transactional integrity in an instant. ECC detects and corrects single‑bit errors on the fly, so your critical data remains exact, while the on‑DIMM register reduces electrical loading on the CPU’s memory controller. For a server running dozens of memory modules, that buffering is what keeps the platform stable and prevents the subtle timing failures that cascade into unscheduled downtime. With a 2933 MT/s speed and CL21 latency, this RDIMM delivers the predictable, low‑overhead performance your virtualized applications and real‑time analytics engines demand—keeping your services online and your data accurate around the clock.

Endurance & Reliability

General Virtualization
Deploy this 64GB RDIMM in dual-socket servers to build dense VM clusters. Two to four modules per host deliver 128–256GB, providing ample headroom for memory overcommitment and live migration in mid-sized environments. Registered ECC ensures data integrity under multi-tenant workloads.

In-Memory Database
Populate all memory channels symmetrically—four or eight identical 64GB DIMMs—to maximize bandwidth for latency-sensitive engines like Redis or SAP HANA. The 2933MHz speed and quad-rank design sustain high throughput on large datasets, while ECC guards against silent corruption during real-time analytics.

High Performance Computing
Fill every channel with these modules to reach 256–512GB per node, ideal for simulation or weather modeling. The 1.2V low voltage reduces thermal load in dense clusters, and registered signaling stabilizes large-capacity configurations under sustained parallel computation. Balance capacity with identical DIMMs to avoid performance penalties from mixed ranks.

Verified Compatibility

Strictly tested for servers: compatible with Dell PowerEdge R750, HPE DL380 Gen10 Plus, Lenovo SR650 V2, and more.
