This DDR3L-1600 ECC unbuffered DIMM is tailored for entry-level servers and compact NAS systems where data integrity must be guaranteed under continuous operation. The single-rank x8 architecture and low 1.35V operating voltage deliver optimal signal integrity and reduced power draw, while built-in ECC correction safeguards against single-bit errors in critical transactional or storage workloads.
1. Error Correction Code actively detects and corrects single-bit memory faults, preserving data integrity in always-on server environments where even minor corruption can cascade into costly downtime.
2. The 1.35V low-voltage operation trims power draw and waste heat at scale, directly reducing energy and cooling overhead inside dense rack-mounted deployments.
3. Unbuffered architecture cuts command-to-data latency, giving single-socket server workloads such as edge caches and lightweight containers a snappier, more deterministic response.
4. DDR3-1600 speed provides a peak bandwidth of 12.8 GB/s, keeping moderate virtualized services and database lookups fed without bottlenecking the CPU’s memory pipeline.
5. CL11 CAS latency shortens the wait between a read request and the first word of data, boosting transactional throughput in latency-bound financial or web-serving applications.
Based on its 240-pin UDIMM form factor, ECC functionality, and dual-voltage 1.35V low-power design, the M391B5773DH0-YK0 is a server-grade memory module purpose-built for entry-level servers, network appliances, and embedded industrial systems. In these environments, the four core attributes translate directly into business continuity and lower operational risk. The ECC engine continuously detects and corrects single-bit memory errors, which means a firewall or small enterprise router processing thousands of packets per second won’t experience the silent data corruption that could route traffic incorrectly or corrupt configuration databases—a guarantee of long-term integrity that standard memory cannot offer. The 1.35V ultra-low voltage operation reduces thermal load inside a fanless industrial controller or a compact 1U edge server, extending component lifespan and cutting energy costs when dozens of these units run 24/7. With a DDR3-1600 clock speed and CL11 latency, the module delivers 12.8 GB/s of bandwidth, letting a lightweight embedded SQL database service concurrent queries without I/O stalls. Finally, the single-rank x8 Unbuffered architecture guarantees the widest electrical compatibility with legacy server chipsets often found in purpose-built medical imaging gateways or digital signage hubs, eliminating boot-time surprises and simplifying field upgrades across a mixed fleet. For the IT manager maintaining a fleet of micro-servers where every watt and every bit matters, this module means predictable uptime, cooler racks, and zero-touch maintenance.
General Virtualization
This DDR3L-1600 ECC UDIMM is designed for entry-level servers and workstations. For general virtualization, populate all dual-channel slots with identical 2GB modules—eight to sixteen sticks provide 16–32GB of reliable capacity. The ECC protection safeguards multiple guest VMs and the 1.35V low-voltage operation reduces power consumption in always-on hosts.
In-Memory Database
In-memory databases demand maximum capacity and data integrity. To overcome the 2GB density, install the motherboard’ full complement of these modules (often 16 or more, yielding 32GB+) in a balanced symmetrical layout across memory channels. Enable ECC to prevent bit errors, but plan for higher-capacity DIMMs if growth is expected, as this single-rank x8 module offers limited headroom for very large datasets.
High-Performance Computing
HPC benefits from both bandwidth and error resilience. Fully populate all memory channels with identical single-rank x8 DIMMs—for example, four modules in a quad-channel platform—to optimize interleaving and throughput. The low 1.35V voltage aids thermal stability during sustained calculations, while unbuffered ECC UDIMM latency remains favorable for tightly coupled parallel jobs.
Validation-tested for servers. Compatible with Dell PowerEdge R210 II, T110 II, HP MicroServer Gen8, Lenovo ThinkServer TS140.
Q: Can I mix this M391B5773DH0-YK0 with other memory modules of different brands or speeds?
A: Mixing is not advised. ECC UDIMMs demand matched specifications for reliable operation. Mismatched speeds or brands may cause POST failures or silent data corruption in server environments.
Q: Is this memory compatible with my system?
A: It fits Intel Xeon E3/E5 v2 single-socket servers and AMD platforms supporting DDR3 ECC UDIMMs. Confirm your board uses 240-pin, 1.35V Unbuffered ECC memory. Always check the system Qualified Vendor List (QVL).
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical modules in pairs across the same channel's slots (usually blue/black sockets) to enable dual-channel mode. Consult the motherboard manual; matching DIMMs in each channel maximizes throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. It follows strict JEDEC DDR3-1600 (PC3-12800) standards. As an ECC UDIMM, it disables overclocking and XMP to ensure data integrity and 24/7 stability for mission-critical applications.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Built with Samsung's premium DRAM chips and stringent testing, it delivers a very low annualized failure rate (AFR) ideal for continuous server workloads.
