Engineer's Note

This 64GB DDR4-2933 Registered ECC RDIMM is purpose-built for enterprise servers and memory-intensive workloads such as virtualization, in-memory databases, and large-scale data analytics. Its quad-rank x4 configuration enables dense memory population while Registered buffering stabilizes signal integrity, and ECC ensures critical data integrity across high-capacity deployments.

Technical Specs & Insights

1. 64 GB capacity per module dramatically increases memory density per server node, enabling higher virtual machine consolidation without sacrificing performance.

2. ECC protection silently corrects single-bit errors and detects multi-bit faults in real time, preserving data integrity for mission-critical enterprise workloads.

3. Registered signal buffering decouples the electrical load from the system memory controller, ensuring stable operation even when all DIMM slots are fully populated.

4. Quad Rank x4 organization interleaves access across multiple internal DRAM banks, sustaining high throughput and keeping latency predictable under heavy multi-tenant demands.

5. 2933 MHz data rate delivers a balance of bandwidth and power efficiency, accelerating in-memory databases and analytics while respecting thermal limits in dense rack deployments.

Why These Specs Matter

For your data center, the HMAA8GR7AJR4N-WMT8AC 64 GB DDR4-2933 RDIMM with ECC and quad-rank x4 architecture directly addresses the fragility of large-scale memory. In virtualization clusters hosting hundreds of VMs, a silent bit error caused by cosmic rays can corrupt a hypervisor or poison guest data; ECC correction automatically detects and repairs such faults, preventing data corruption and costly downtime. Registered buffering isolates the memory controller from electrical loading, allowing you to fully populate 12 DIMM slots per server for terabyte-scale capacity without signal instability—vital for in-memory databases like SAP HANA and Redis, where running out of capacity triggers prohibitive performance drops. The quad-rank x4 design at 2933 MHz enables rank interleaving that hides refresh latencies, delivering consistent bandwidth for mixed OLTP and real-time analytics workloads. This module transforms raw specifications into uptime assurance and predictable, low-latency performance.

Endurance & Reliability

Capacity Planning Guide for Server Memory (64GB DDR4-2933 ECC RDIMM)

When deploying Hynix 64GB DDR4-2933 registered ECC modules in enterprise servers, align your configuration with workload demands to maximize performance, reliability, and memory bandwidth.

General Virtualization
For consolidating multiple virtual machines, populate at least six to eight identical 64GB RDIMMs per host to achieve balanced memory channels and a total capacity of 384–512GB. This provides ample headroom for VM density while registered ECC ensures data integrity across shared resources. Deploy modules uniformly across all memory channels to maintain symmetric multi-threaded performance.

In-Memory Database
In-memory databases such as SAP HANA or Redis require both large capacity and high availability. Equip the server with 12 to 24 of these 64GB modules for 768GB–1.5TB configurations, leveraging quad-rank design to maximize per-slot density. Enable memory mirroring or rank sparing via the BIOS to protect against uncorrectable errors in mission-critical transactional workloads.

High-Performance Computing
HPC clusters benefit from maximum aggregate bandwidth and low latency. Populate all available memory channels with one 64GB RDIMM per channel (one DIMM per channel, or 1DPC) to sustain 2933MT/s speed without throttling. A typical dual-socket node with 8 channels each would use 16 modules, delivering 1TB of total capacity for large simulation datasets while preserving peak throughput.

Verified Compatibility

Rigorously tested, this server RDIMM guarantees compatibility with Dell PowerEdge R760, HPE ProLiant DL380 Gen10, and more.
