Engineer's Note

This 48 GB DDR5-6400 Registered ECC RDIMM is purpose-built for enterprise servers and data-center platforms running memory-intensive workloads like virtualization, in-memory databases, and large-scale data analytics. The single-rank x4 organization enables stable, low-latency operation at CL52 while registered signal buffering and full ECC safeguard data integrity across densely populated memory channels.

Technical Specs & Insights

1. A 48-gigabyte capacity unlocks non-binary density, enabling virtualized and containerized workloads to access more memory per channel without occupying additional DIMM slots.
2. The 6400 megatransfers per second data rate elevates throughput for in-memory databases and real-time analytics, trimming response latency under heavy query concurrency.
3. On-die ECC transparently corrects single-bit errors, guarding transactional integrity and uptime in financial, medical, and hyperscale operations.
4. Registered clock drivers stabilize command and address signals across densely populated servers, ensuring reliable operation when scaling to multi-terabyte footprints.
5. DDR5 technology doubles bank groups and burst length, supplying the sustained bandwidth that modern server processors demand for parallel data-hungry tasks.

Why These Specs Matter

Built for the data center, this RDIMM is engineered to solve the real challenges that keep IT architects awake at night. When you are running a dense virtualization cluster, a single undetected bit flip in a hypervisor’s memory can crash dozens of production VMs. The on‑die ECC of this module corrects single‑bit errors transparently, directly guarding against data corruption that would otherwise translate into revenue loss. Its Registered clock driver buffers command and address signals, which means you can populate all memory channels with stable, high‑capacity DIMMs—this is non‑negotiable when your consolidated workloads demand hundreds of gigabytes of reliable RAM without signal degradation. The 48 GB capacity paired with a single‑rank‑x4 organization is purpose‑tuned for memory databases like SAP HANA or Redis. A single rank means lower electrical loading on the memory bus, allowing the DDR5‑6400 speed to sustain higher bandwidth under heavy read‑write concurrency, so your in‑memory analytics deliver real‑time insights without throttling. Every transaction, every query, and every virtual machine depends on this combination of integrity, signal stability, and raw throughput—it is not just a spec sheet, it is your uptime.

Endurance & Reliability

General Virtualization
Populate each memory channel with a single 48 GB RDIMM (1DPC) to run at the full 6400 MT/s. This yields balanced capacity for typical virtualization hosts. For higher VM density, install two modules per channel, expecting a slight speed drop. The ECC protection guards against data corruption in multi-tenant environments.

In-Memory Database
Equip every channel with two identical 48 GB RDIMMs (2DPC) to maximize per-channel capacity and memory interleaving. This provides 96 GB per channel for in-memory databases and low-latency caches. Maintain symmetrical population to avoid NUMA imbalance. Opt for these RDIMMs to leverage full RAS features.

High-Performance Computing
For HPC workloads, use a 1DPC configuration with a 48 GB RDIMM in each channel to deliver maximum memory bandwidth at 6400 MT/s. The resulting capacity meets most simulation and modeling needs. Reserve 2DPC only when larger datasets are unavoidable, trading off some frequency.

Verified Compatibility

This rigorously tested 48GB DDR5-6400 RDIMM is compatible with Dell R760, HPE DL380 Gen11, Lenovo SR650 V3.
