This Samsung M393A4G43CB4-CWEGY is a 32GB DDR4-3200 Registered ECC DIMM engineered for enterprise servers and workstations running memory-intensive, mission-critical workloads such as virtualization, in-memory databases, and real-time analytics. Its dual-rank x8 organization maximizes interleaving efficiency for higher sustained bandwidth, while the registered signal architecture and ECC ensure signal integrity and single-bit error correction across densely populated server boards, directly safeguarding data integrity under continuous operation.
1. Registered signal type buffers the command and address lines, enabling the deployment of massive memory populations without compromising signal integrity in dense server racks.
2. ECC error detection and correction silently scrubs single-bit flips caused by background radiation, preserving data accuracy across months-long uptime cycles.
3. A 32GB module capacity dramatically expands the memory footprint per CPU socket, allowing virtualization hosts to run more concurrent guest machines without swapping to slower storage.
4. Dual Rank x8 organization interleaves access across two internal ranks on a single DIMM, raising effective bandwidth for in-memory databases under sustained query loads.
5. DDR4-3200 speed feeds modern server CPUs with sufficient throughput per channel to saturate high-core-count processors during parallel analytics workloads, reducing job completion time.
Judging by the Registered signal type, ECC error correction, and standard DIMM form factor, the Samsung M393A4G43CB4-CWEGY is unmistakably server-grade memory. In your data center, this module’s four core characteristics directly translate into resilience and performance where it matters most. The 3200 MT/s DDR4 speed feeds your CPU with 25.6 GB/s of bandwidth per channel, so a virtualized cluster hosting dozens of VMs won’t stutter when critical services spike—each VM slice stays responsive under concurrent load. ECC is non-negotiable here: a single bit-flip from background radiation can corrupt in-memory database transactions or silently alter financial calculations. This module detects and corrects single-bit errors on the fly, protecting data integrity for platforms like SAP HANA or VMware vSAN that run entirely in RAM. The Registered buffer stabilizes signals when you populate multiple DIMMs per channel, essential for scaling to hundreds of gigabytes without memory training failures or boot-time surprises. Meanwhile, the Dual Rank x8 organization interleaves internal banks to deliver noticeably higher effective bandwidth—an in-memory analytics query that would stall on a single-rank stick now sees reduced latency and faster result retrieval. In a dense virtualization host or a high-throughput database server, these features lift your workload ceiling while guarding against silent data corruption that could cost hours of recovery.
General Virtualization
Deploy this 32GB DDR4-3200 ECC Registered DIMM in a balanced population across all memory channels to maximize bandwidth and capacity. For a dual-socket server with eight channels per CPU, install one module per channel for a total of 256GB (8×32GB) at 1 DIMM Per Channel (DPC), sustaining full 3200 MT/s speed. This configuration provides ample headroom for dozens of mixed-application VMs while maintaining reliable error correction.
In-Memory Database
Maximize total capacity by populating two of these dual-rank modules per channel (2DPC) on a server supporting 16 DIMM slots per CPU, yielding 512GB per socket. Though speed may reduce to 2933 MT/s at 2DPC, the sheer volume accelerates in-memory analytics and Redis or SAP HANA workloads. Ensure uniform module placement for consistent latency and leverage interleaving across channels for optimal throughput.
High-Performance Computing
For latency-sensitive HPC simulations, mount one 32GB RDIMM per channel (1DPC) to retain the full 3200 MT/s frequency, delivering roughly 204.8 GB/s of theoretical bandwidth per CPU on an 8-channel platform. Scale total capacity by adding identical modules across empty channels rather than stacking ranks, preserving peak memory bandwidth per core. This approach suits CFD, molecular dynamics, and large-scale parallel numerical workloads.
Validated for servers: rigorously tested, compatible with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650 V2, and more.
Q: Can I mix this M393A4G43CB4-CWEGY with other memory modules of different brands or speeds?
A: For server environments, mixing different brands or speeds is not recommended. It can cause instability and compatibility issues. Always use identical modules to ensure reliable performance and avoid system errors.
Q: Is this memory compatible with my system?
A: This DDR4-3200 ECC Registered DIMM is compatible with server platforms supporting RDIMM, such as Intel Xeon Scalable and AMD EPYC. Please verify your motherboard's QVL or HCL for exact support.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard’s manual. Typically, populate identical DIMMs in balanced numbers across all memory channels per CPU, filling slots per channel starting from the furthest from the CPU.
Q: Does this module support overclocking or XMP profiles?
A: No. This is an ECC Registered server memory module, designed for stability. It operates at JEDEC standard timings and does not support overclocking or XMP profiles.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a one-year warranty. Server-class memory is tested for high reliability and exhibits a very low AFR, typically under 0.44% as per industry standards.
