Designed for server platforms, this DDR5-5600 Registered ECC RDIMM leverages Dual Rank organization and 1.1V power efficiency to maximize memory bandwidth and data integrity in virtualization, in-memory databases, and mission-critical workloads. Its 288-pin Registered architecture with full ECC and CL46 latency ensures exceptional signal stability and reliability under heavy, continuous load.
1. Registered clock driver architecture decouples electrical loading, allowing fully populated server memory channels to maintain rock‑solid command and address integrity for dense virtualization hosts.
2. ECC scrubbing and single‑bit correction safeguard in‑memory data against corruption, which is essential for transactional databases and long‑running analytics pipelines where silent errors are unacceptable.
3. Dual‑rank organization interleaves access across internal banks, keeping the memory pipeline saturated to deliver consistent multi‑tenant performance under heavy consolidation spikes.
4. The high‑speed DDR5 interface shortens data fetch cycles, directly accelerating in‑memory caches and real‑time streaming workloads that demand low‑latency bulk throughput.
5. The modest per‑module capacity granularity enables finely graduated memory scaling, letting cloud operators hit optimal cost‑per‑gigabyte ratios when building out large server fleets.
When you are running a dense virtualization cluster or an in-memory database like SAP HANA, memory errors are not just a nuisance—they are a direct threat to business continuity. The Samsung M321R2GA3PB0-CWMXJ is a DDR5-5600 Registered DIMM purpose‑built for these realities. Its ECC continuously detects and corrects single‑bit flips caused by background radiation or electrical noise, preserving data integrity in transactions where even one corrupted bit can crash a database or silently poison a virtual machine’s state. The Registered clock driver buffers command and address signals, allowing your server to populate all DIMM slots without signal degradation—this means you can confidently scale to hundreds of gigabytes of memory for sprawling virtualization hosts. Dual‑rank organization further elevates performance by interleaving accesses across two internal ranks, effectively overlapping latency and raising effective bandwidth under the heavy, random access patterns typical of multi‑tenant virtual machines. Finally, the native 5600 MT/s speed delivers the throughput needed to keep pace with modern multi‑core server CPUs, while the efficient 1.1 V operation helps rein in the cooling and energy costs that dog dense datacenter deployments. This module transforms raw specifications into uncompromised reliability and throughput where downtime is unacceptable.
General Virtualization
This 16GB DDR5-5600 Registered ECC DIMM is ideal for virtualization hosts demanding assured stability. Install one module per memory channel (eight modules per CPU socket) to deliver 128GB of balanced capacity without sacrificing bandwidth. ECC and registered signal integrity prevent data corruption across numerous VMs, supporting dense consolidation reliably.
In-Memory Database
For in-memory databases, maximize protected capacity by fully populating both DIMM slots per channel. Using 32 of these 16GB RDIMMs in a dual-socket server provides 512GB of fault-tolerant memory, keeping entire datasets resident. The registered design ensures clean signal quality at high density, enabling fast, consistent real-time analytics.
High Performance Computing
HPC workloads require maximum sustained bandwidth and computational accuracy. Populate all memory channels with at least one dual-rank 16GB module per channel—two per channel can be added for capacity—to leverage full 5600MT/s speed. Dual rank interleaving enhances throughput, while ECC and registered operation safeguard long-running parallel simulations.
Rigorously tested server memory, compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3.
Q: Can I mix this M321R2GA3PB0-CWMXJ with other memory modules of different brands or speeds?
A: Mixing is not recommended. Server platforms demand strict uniformity. Using mismatched modules risks instability and disables memory RAS features. Always populate with identical part numbers for validated reliability.
Q: Is this memory compatible with my system?
A: This RDIMM is designed for servers supporting DDR5-5600 Registered ECC memory. Verify your Intel Xeon Scalable or AMD EPYC platform explicitly supports 16GB Dual-Rank DIMMs at PC5‑44800 speeds on its Qualified Vendor List.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board's memory slot numbering. Typically, populate identical DIMMs per channel, starting with the furthest slot first. Balanced dual-rank configuration ensures maximum interleaving and throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This enterprise Registered DIMM complies strictly with JEDEC DDR5-5600 CL46 standards. Overclocking or XMP is disabled to guarantee signal integrity and ECC functionality in mission-critical environments.
Q: What warranty and typical failure rate can I expect?
A: It includes a 1‑year warranty. Enterprise RDIMMs exhibit an extremely low annualized failure rate, typically within industry AFR standards. Contact support for detailed MTBF specifications.
