Engineer's Note

Designed for enterprise servers, this 32GB DDR4-2400 RDIMM operates at 1.2V and leverages Registered signaling with ECC to ensure data integrity in demanding virtualized and memory-database workloads. Its Quad Rank x4 organization maximizes capacity density per channel while the CL17 latency provides a stable balance between access speed and error-free operation on AMD EPYC and Intel Xeon platforms.

Technical Specs & Insights

1. ECC protection detects and corrects single-bit errors in real time, ensuring uncompromised data integrity for mission-critical enterprise workloads like financial ledgers and virtualized databases.
2. Registered signal buffering stabilizes command and address lines, enabling high-capacity memory populations essential for large-scale server consolidation scenarios.
3. Quad Rank x4 organization keeps all memory channels deeply saturated, delivering predictable low-latency access even under heavy multi-tenant cloud bursts.
4. The spacious module capacity allows denser memory configurations per server node, directly reducing deployment footprint while expanding in-memory dataset headroom.
5. DDR4-2400 throughput provides a balanced mix of generous bandwidth and modest power draw, sustaining continuous compute loads without exceeding typical data-center thermal limits.

Why These Specs Matter

The Samsung M386A4G40EM2-CRC5Q is a 32GB DDR4-2400 Registered DIMM built specifically for server environments where downtime is simply not an option. Four architectural features directly address the pain points of IT infrastructure teams. First, integrated ECC silently corrects single-bit memory errors caused by background radiation or electrical noise, preventing silent data corruption in always-on virtualized clusters—this means your hypervisor and guest VMs stay stable without mysterious crashes. Second, the Registered buffer re-drives address and command signals, enabling fully populated memory channels across all slots without signal degradation; for a dense virtualization host running dozens of workloads, this guarantees reliable communication even at maximum capacity. Third, the Quad Rank x4 organization unlocks deep memory interleaving, boosting sustained bandwidth for read-latency-sensitive in-memory databases like SAP HANA or Redis, where each microsecond of delay directly impacts transaction throughput. Finally, the generous 32GB capacity per DIMM maximizes density per slot, reducing total module count and preserving precious chassis space while lowering power and cooling overhead. With 1.2V efficiency and proven 2400MT/s speed, this module delivers the rock-solid data integrity and scalable performance your business-critical applications demand.

Endurance & Reliability

General Virtualization
This 32GB DDR4-2400 RDIMM is ideal for moderate-density virtualization hosts. A balanced configuration of four to eight such modules (128–256GB total) allows reliable hosting of dozens of virtual machines with ECC protection. Deploy in symmetric channels to maintain memory bandwidth and reserve headroom for hypervisor overhead.

In-Memory Database
For in-memory databases like Redis or SAP HANA, capacity and data integrity are paramount. Populate all available channels with identical 32GB Registered ECC modules to maximize capacity while the x4 Quad Rank design ensures robust error correction under heavy write loads. Start with a minimum of 256GB across eight DIMMs and scale by adding identical kits for seamless capacity expansion.

High-Performance Computing (HPC)
HPC workloads demand both bandwidth and resilience. Install six or eight of these RDIMMs in a balanced multi-channel layout (e.g., one DIMM per channel) to deliver steady 2400 MT/s throughput with ECC. The Quad Rank construction suits dense nodes running memory-sensitive simulations, but verify rank limits per channel to avoid downclocking.

Verified Compatibility

This server memory has been rigorously tested for seamless compatibility with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, and more.
