This Samsung M392B1G73DB0-YK0 is a server-grade DDR3 VLP RDIMM with ECC and registered signal technology, ideally suited for memory-intensive server workloads such as virtualization and in-memory databases where data integrity is paramount. Its single-rank x8 configuration reduces electrical loading on the memory bus for improved signal integrity, while the 1.35V low operating voltage and CL11 latency deliver an optimal balance of power efficiency and responsive data access.
1. ECC protection continuously detects and corrects memory errors, preserving data integrity for mission-critical enterprise workloads that cannot tolerate silent corruption.
2. Registered buffer architecture reduces the electrical load on the memory controller, enabling stable high-capacity memory populations essential for heavy virtualization and large in-memory databases.
3. The very low-profile design allows installation in space-constrained rack servers and blade enclosures, improving airflow and simplifying hardware maintenance in dense data center environments.
4. Low-voltage operation minimizes overall power draw and waste heat, helping operators reduce energy expenses and sustain thermal headroom in densely packed server racks.
5. Proven DDR3 reliability delivers consistent read/write throughput, offering a cost-effective performance baseline for legacy-scale hosting and stable multi-tenant service delivery.
The Samsung M392B1G73DB0-YK0 is a server-grade DDR3 VLP RDIMM, and its four defining characteristics directly solve the real reliability and performance challenges that keep IT managers awake at night.
First, the ECC error correction is non-negotiable in any memory-intensive server environment. When you are running an in-memory database like Redis or SAP HANA, a single-bit flip caused by background radiation can silently corrupt financial transactions or customer records. ECC detects and corrects these errors in real time, transforming a potential data integrity disaster into a non-event. Second, the Registered buffer is what makes large-scale virtualization possible. In a VMware or Hyper-V cluster hosting dozens of VMs, populating all memory slots without a register chip would overload the CPU’s memory controller, causing boot failures and random crashes. The RDIMM buffer stabilizes those electrical loads so you can reliably scale to 192GB or more per server. Third, the single-rank x8 organization and 1600MHz speed at a tight CL11 latency deliver the predictable, low-jitter bandwidth that virtualized workloads demand; it prevents the CPU from stalling when multiple VMs fight for data. Finally, the 1.35V low-voltage operation and VLP form factor are critical in dense blade servers and 1U rackmounts: lower voltage means less heat and reduced energy cost over a farm of 500 nodes, while the very low profile allows the module to fit into slim chassis where airflow is already challenged, preventing thermal throttling and extending hardware lifespan.
This Samsung 8GB DDR3L-1600 Registered ECC RDIMM suits server platforms. Below is capacity planning for three workloads.
General Virtualization
Populate both CPU memory controllers with at least eight identical 8GB modules (64GB total) to enable channel interleaving and balanced performance. For higher density, install sixteen modules (128GB) using two DIMMs per channel, supporting 20–30 moderate VMs without significant bandwidth penalty.
In-Memory Database
Maximize capacity by filling all DIMM slots—24 slots yield 192GB. Ensure modules are evenly spread across channels for uniform access, and rely on ECC for data integrity. The 1.35V VLP design helps manage thermals in fully loaded systems.
High-Performance Computing
For peak bandwidth, install only one DIMM per memory channel to maintain 1600MT/s. Eight modules (64GB) across a dual-socket platform with four channels each deliver optimal throughput. If capacity is paramount, two DIMMs per channel are acceptable, but speed may degrade to 1333MT/s.
Verified compatible after rigorous testing with Dell PowerEdge R720, R620, HP DL380p Gen8, and similar servers.
Q: Can I mix M392B1G73DB0-YK0 with other memory modules of different brands or speeds?
A: Mixing is not recommended. This registered ECC RDIMM must match identical speed, CAS latency, and rank to ensure system stability. Mixing different specs may cause POST failures or memory errors in server environments.
Q: Is this memory compatible with my system?
A: This is a DDR3-1600 VLP RDIMM designed for servers using Intel Xeon E5/E7 v2 or AMD Opteron 6300/4300 series platforms. Verify your motherboard supports 1.35V registered ECC memory with 240-pin slots.
Q: What is the recommended DIMM population order for optimal performance?
A: Always populate identical DIMMs per memory channel following the server motherboard’s population guide. Typically, install matched pairs starting with the farthest slot from the CPU for balanced channel interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-class registered DIMM, it strictly follows JEDEC DDR3-1600 timings. Overclocking and XMP profiles are disabled to ensure 24/7 data integrity and error-free ECC operation.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. With rigorous binning and ECC design, the annualized failure rate is below 0.3% under normal server operating conditions.
