This 32GB DDR4-3200 ECC Unbuffered DIMM is designed for entry-level workstations and small servers that demand data integrity, excelling in tasks like file storage, light virtualization, and archival databases. Its dual-rank x8 organization maximizes memory bandwidth under multi-process workloads, while ECC error correction and a low CL22 latency ensure rock-solid stability and responsive performance at an efficient 1.2V.
1. 32GB density per module allows a single server node to host more virtual machines comfortably, maximizing consolidation ratios without immediate investment in extra hardware.
2. ECC protection detects and corrects single-bit memory errors on the fly, preventing silent data corruption that could crash critical financial or database workloads.
3. 3200MT/s transfer rate delivers the elevated memory bandwidth needed to keep modern multi-core server CPUs fed, accelerating real-time analytics and in-memory caching.
4. Dual Rank x8 organization leverages rank interleaving to overlap read/write bursts, sustaining higher throughput during concurrent user requests and enterprise application peaks.
5. 1.2V operation reduces power draw per DIMM, lowering cumulative thermal output and energy costs in dense rack deployments where efficiency directly impacts OpEx.
Designed for server and workstation platforms, the Samsung M391A4G43AB1-CWEQY is a 32GB DDR4-3200 UDIMM that brings enterprise-grade reliability and performance to critical workloads. Its ECC (Error Correcting Code) capability continuously detects and corrects single-bit memory errors, a silent threat that can corrupt financial records, compromise virtualization integrity, or cause unexplained crashes in a 24/7 database environment. In a virtualized cluster running multiple VMs, a single undetected bit-flip can cascade into data loss or service downtime; ECC turns that risk into a safely corrected event without interrupting operations. The dual-rank x8 organization further enhances real-world throughput by allowing the memory controller to interleave access across two internal rank groups, reducing latency and boosting bandwidth during memory-intensive tasks like in-memory databases or real-time analytics. With a 3200MT/s speed and a standard 1.2V operating voltage, this module balances swift data transfer with power efficiency, helping to manage thermal loads in dense server chassis. For small-to-medium business servers, NAS appliances, or engineering workstations where data integrity and consistent performance are non-negotiable, this UDIMM seamlessly delivers the stability and responsiveness your applications demand.
General Virtualization
For a host running moderate-density VMs, populate at least two identical 32 GB ECC UDIMMs in dual-channel configuration. A 64 GB total allows comfortable overcommitment while safeguarding data integrity. In larger hypervisor deployments, scale to four modules (128 GB) to accommodate memory-hungry guest fleets without swapping to disk.
In-Memory Database
In-memory engines such as Redis or SAP HANA demand sheer capacity and low latency. Install four or eight of these 32 GB dual-rank DIMMs to reach 128–256 GB, using one DIMM per channel whenever possible to maintain full access bandwidth. The combination of unbuffered ECC and 3200 MT/s speed helps keep query response times deterministic under load.
High-Performance Computing
HPC nodes benefit from balanced memory bandwidth and capacity per core. Populate all available channels with one 32 GB module each—typically eight DIMMs for a mainstream dual-socket platform—to achieve 256 GB and maximum throughput. This arrangement feeds parallel scientific workloads efficiently while ECC guards against silent data corruption during long-running simulations.
Server-grade DDR4 ECC UDIMM, rigorously tested, compatible with Dell PowerEdge T150, HPE ML30 Gen10 Plus, Lenovo ST250 V2.
Q: Can I mix this M391A4G43AB1-CWEQY with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not advised for server memory. Identical part numbers maintain signal integrity and prevent instability. Mismatched UDIMMs may lead to POST failures or silent data corruption.
Q: Is this memory compatible with my system?
A: This 32GB DDR4-3200 ECC UDIMM targets servers and workstations with unbuffered ECC support, such as Intel Xeon E-2300/E-2200 and AMD Ryzen PRO platforms. Consult your motherboard's qualified vendor list for confirmation.
Q: What is the recommended DIMM population order for optimal performance?
A: Install identical DIMMs per memory channel, starting from the slot farthest from the CPU. With dual-rank x8 modules, balance ranks symmetrically across channels according to your server board's population guidelines for best bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, it strictly follows JEDEC DDR4-3200 (CL22) standards. Server UDIMMs like this one do not support XMP or overclocking, as they prioritize error-free operation and long-term data integrity over variable clock speeds.
Q: What warranty and typical failure rate can I expect?
A: It comes with a 1-year warranty. Built with Samsung components, this module exhibits an extremely low annualized failure rate typical of enterprise-grade memory, ensuring high reliability for critical workloads.
