This DDR4-2933 ECC Unbuffered DIMM is purpose-built for entry-level servers and workstations, delivering critical data integrity for virtualization, memory caching, and database workloads where silent data corruption cannot be tolerated. Its dual-rank x8 configuration optimizes memory interleaving to boost throughput stability, while the standard 1.2V operating voltage supports sustained reliability in 24/7 operations.
1. ECC protection continuously corrects single-bit memory errors, preserving data integrity for always-on services and preventing costly silent corruption in entry-level server workloads.
2. A 16‑gigabyte footprint gives small virtualization hosts enough headroom to run multiple containers or lightweight VMs without immediate scaling pressure.
3. DDR4‑2933 throughput accelerates data movement across memory channels, reducing latency spikes during concurrent database lookups and file‑serving operations.
4. Dual‑rank x8 organization interleaves bank accesses to keep command pipelines full, sustaining high bandwidth under mixed‑workload conditions typical of small business servers.
5. Unbuffered design eliminates register latency and lowers platform cost, delivering quick response times for budget‑conscious server deployments where efficiency matters.
When building a reliable server or professional workstation, data integrity and responsive performance are non-negotiable. The Samsung M391A2K43DB1-CVF is a 16GB DDR4-2933 ECC Unbuffered DIMM engineered precisely for these demands, bringing four critical strengths to your real-world workloads. Its on-die Error Correction Code (ECC) silently detects and corrects single-bit memory errors, a vital defense when running a virtualized cluster or a financial transaction database where a flipped bit can crash hypervisors or silently corrupt ledger entries. The dual-rank x8 organization interleaves memory accesses to boost bandwidth under heavy loads; multiple virtual machines running simultaneously or an in-memory caching system like Redis will experience noticeably smoother throughput and reduced latency compared to single-rank alternatives. Operating at a brisk 2933 MT/s with a CAS latency of 21, this module accelerates large dataset lookups and real-time analytics, shortening query times that directly impact user-facing applications. Meanwhile, its low 1.2V DDR4 voltage cuts power consumption and thermal stress inside dense server chassis, lowering your op-ex and extending the life of nearby components. For hosting a ZFS storage array or maintaining 24/7 uptime on a small virtualization host, this ECC UDIMM means you deploy compact, cost-effective servers without sacrificing the stability that your data and users depend on.
General Virtualization
For a dual-socket server with six or eight memory channels per CPU, populate all channels with one 16GB ECC UDIMM each to maintain the rated DDR4-2933 speed. This balanced 96–128 GB configuration delivers solid VM density while avoiding performance penalties from mixing ranks per channel. Avoid populating only a single channel, as that starves the memory controller of the bandwidth virtualization workloads demand.
In-Memory Database
In-memory databases thrive on capacity and latency-sensitive throughput. Fill every available DIMM slot with dual-rank x8 16GB modules to maximize total capacity – for a typical single-socket platform with four channels and two DIMMs per channel, eight modules yield 128 GB. The dual-rank design boosts rank-level parallelism, improving response times under heavy random access. ECC is non-negotiable here to prevent silent data corruption.
High Performance Computing (HPC)
HPC codes often scale with bandwidth, so configure one 16GB module per channel to sustain 2933 MT/s without downclocking. For an eight-channel workstation or server, eight sticks provide 128 GB of balanced bandwidth. If capacity must grow, double the DIMMs per channel but test performance, as unmatched dual-rank loading may force a frequency drop to 2666 MT/s.
This server memory is rigorously tested and compatible with Dell PowerEdge R250, HPE ProLiant DL20 Gen10, and Lenovo ThinkSystem ST250.
Q: Can I mix this M391A2K43DB1-CVF with other memory modules of different brands or speeds?
A: Mixing brands or speeds in servers is discouraged. It may cause instability or ECC errors. For guaranteed reliability, use identical modules. Mismatched DIMMs typically force all memory to the lowest common speed.
Q: Is this memory compatible with my system?
A: This DDR4-2933 ECC UDIMM targets Intel Xeon E-2100/2200 and AMD Ryzen Pro platforms with chipsets like C246. Verify your board supports 16GB Dual Rank x8 ECC UDIMMs before purchase.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, starting with the first slot of each channel. Follow your server board’s manual for specific slot numbering to enable memory interleaving and maintain balanced configurations.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server memory with fixed timings. It does not support XMP or overclocking; stability and data integrity are prioritized over performance tuning.
Q: What warranty and typical failure rate can I expect?
A: It includes a 1-year warranty. Samsung modules have an annualized failure rate typically below 0.5% under normal server conditions, offering robust reliability for business-critical workloads.
