Engineer's Note

This Samsung 8GB DDR4-2400 RDIMM is purpose-built for virtualization and in-memory database workloads where the dual-rank x8 architecture maximizes memory bandwidth and capacity per channel. Its registered ECC design enforces signal integrity across fully populated servers and provides seamless single-bit error correction, making it essential for platforms that demand continuous data integrity under heavy, sustained loads.

Technical Specs & Insights

1. ECC error correction silently detects and fixes single-bit memory errors, preserving data integrity for financial transactions and long-running analytics jobs.
2. Registered signal buffering stabilizes electrical loads across fully populated server channels, enabling dense memory configurations vital for large-scale virtualization hosts.
3. Dual Rank x8 organization leverages rank interleaving to amplify effective bandwidth, reducing latency under mixed workload conditions in multi-tenant platforms.
4. An 8GB capacity per module offers a right-sized building block for lightweight container orchestration or edge caching appliances where density is balanced against cost.
5. 2400MHz operation with CL17 timing delivers steady, predictable throughput that matches the sustained request rate of standard enterprise applications without thermal overstress.

Why These Specs Matter

When deploying a virtualization cluster or an in-memory database, the M393A1G43EB1-CRC4Q RDIMM becomes the foundation of predictable, always-on performance rather than just another component. Its ECC technology continuously scans and corrects single-bit errors before they corrupt transactional records or silently flip a critical bit inside a cached dataset. That is the difference between a clean financial report and a silent data inconsistency that takes days to trace. The registered signal buffer isolates the memory controller from excessive load, letting you populate all channels with confidence while running dozens of VMs on a single node without signal degradation. Built as a dual-rank x8 module, it interleaves internal banks to sustain bandwidth under the heavy, random-access patterns of Redis or SAP HANA. And because it operates at just 1.2 volts, a fully populated rack of these DDR4-2400 modules draws less power and generates less heat, which directly lowers cooling costs in a colocation facility. For IT architects who measure memory by uptime, data integrity, and watt per gigabyte, this module turns specs into real operational savings and unwavering stability.

Endurance & Reliability

General Virtualization
Balance capacity and cost by populating six to eight of these 8 GB RDIMMs (one DIMM per channel) in a dual‑socket server to deliver 48–64 GB. This supports dozens of light to medium VMs while maintaining symmetric memory access across NUMA nodes for stable consolidation.

In‑Memory Database
Maximize capacity by fully loading all DIMM slots—up to 24 modules in a dual‑socket server for 192 GB—or pair with larger RDIMMs for growing datasets. Distribute modules evenly across all memory channels and enable rank interleaving to lower latency and sustain high transactional throughput.

High‑Performance Computing (HPC)
Per node, install eight identical 8 GB RDIMMs (two per channel on a four‑channel platform) to reach 64 GB and guarantee uniform memory bandwidth per core. Strictly match all modules in speed and rank to avoid performance skew, which is critical for tightly‑coupled parallel jobs and MPI scaling.

Verified Compatibility

Rigorously tested for seamless compatibility with servers such as Dell PowerEdge R740, HPE ProLiant DL380 Gen10, and Lenovo ThinkSystem SR650.
