This DDR5-5600 registered ECC RDIMM with a dual-rank configuration is purpose-built for enterprise server platforms handling memory-intensive workloads like virtualization and in-memory databases, where data integrity and uptime are critical. The registered signal type stabilizes high-capacity memory channels under heavy load, while dual-rank interleaving boosts effective bandwidth and ECC protection eliminates single-bit errors to safeguard transactional accuracy.
1. Registered signal architecture ensures stable command and address signaling across multiple DIMMs per channel, enabling large memory footprints essential for enterprise virtualization without compromising reliability.
2. Integrated ECC transparently corrects single-bit memory errors, delivering the data protection required for transaction-heavy databases and 24/7 critical services.
3. DDR5 technology boosts per-channel bandwidth and bank groups, sustaining throughput for dense multi-core server processors under heavy concurrent workloads.
4. 16 GB module capacity scales seamlessly in multi-slot server boards, maximizing virtual machine density and in-memory application headroom per rack unit.
5. 5600 MT/s speed slashes transfer latency for large in-memory analytics, accelerating real-time decision-making and reducing query completion times.
Engineered for the exacting demands of modern data centers, the M321R2GA3PB0-CWM is a 16GB DDR5-5600 Registered DIMM that directly answers the critical pain points of server administration. Its ECC technology is your silent guardian against silent data corruption. In a dense virtualization cluster hosting dozens of VMs, a single undetected bit flip in a cosmic ray-prone environment can cascade into hypervisor crashes and costly service interruptions. ECC proactively corrects these errors, preserving transactional integrity and uptime in your virtualized infrastructure.
The Registered signal type, using an onboard command/address buffer, stabilizes high-capacity memory channels. When populating a server to support massive in-memory databases like Redis or SAP HANA, the reduced electrical load per channel lets you confidently scale without sacrificing signal integrity, preventing boot failures under full load. Complementing this, the Dual Rank organization interleaves access across two internal 8GB tiers, substantially boosting sustained bandwidth. This means your latency-sensitive database queries complete faster because the memory controller can hide precharge delays, delivering superior IOPS for real-time analytics. Meanwhile, the 1.1V ultra-low power envelope and 5600MT/s data rate maximize throughput-per-watt, cutting thermal overhead so your colocation costs stay lean while your workloads run flat-out.
This DDR5-5600 Registered ECC DIMM (16GB, dual-rank) is built for server-class workloads where data integrity and stability are paramount. Below are capacity planning recommendations for typical server scenarios.
General Virtualization
Populate all memory channels equally to maximize bandwidth and VM density. For a dual-socket server with eight channels per CPU, install sixteen 16GB modules (one per channel, 256GB total) to support dozens of moderate VMs at full 5600 MT/s. Add a second DIMM per channel only if total capacity must exceed 256GB, accepting a possible speed reduction to 4800 MT/s.
In-Memory Database
Capacity is critical for holding entire datasets in RAM. Using these 16GB RDIMMs, fill all available slots in a dual-socket server—typically 32 modules (512GB) at two DIMMs per channel—to maximize memory for in-memory analytics. ECC reliability protects against data corruption under heavy transactional loads.
High-Performance Computing
HPC workloads crave bandwidth. Install one 16GB DIMM per channel (16 modules, 256GB) to sustain peak DDR5-5600 speed and maximize per-socket throughput for simulations. When larger working sets demand more capacity, scale to 32 modules (512GB) with 2DPC while understanding the modest frequency trade-off; however, for floating-point-heavy codes, always favor 1DPC.
Rigorously tested server memory. Compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3, Supermicro X13 systems.
Q: Can I mix this M321R2GA3PB0-CWM with other memory modules of different brands or speeds?
A: Mixing with different brands or speeds is not recommended. Dissimilar modules may cause instability, as registered ECC memory requires matched ranks, timings, and identical specifications for reliable server operation.
Q: Is this memory compatible with my system?
A: This DDR5-5600 RDIMM is designed for servers supporting registered ECC memory. Verify your board or system supports DDR5 RDIMM at 5600MT/s and a compatible Intel Xeon Scalable or AMD EPYC platform.
Q: What is the recommended DIMM population order for optimal performance?
A: Always populate identical modules per channel following the server manual. Fill all channels symmetrically, starting with the slot farthest from the CPU, to maximize bandwidth and memory interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade registered ECC module that adheres to JEDEC standards. It does not support XMP or overclocking; data integrity and system stability take priority over speed adjustments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise-class RDIMMs are highly reliable, with typical annual failure rates below 0.5% when operated within specified environmental and electrical parameters.
