Product overview for the Dell SNPDFK3YC/16G

In the ever-evolving landscape of technology, server memory plays a crucial role in the performance and reliability of servers. One such product in focus is the Dell SNPDFK3YC/16G, a 16GB DDR4 SDRAM memory module designed specifically for servers. In this detailed explanation, we will delve into the key specifications and features of this memory module, decoding its nomenclature and exploring its significance in the realm of server technology.

Decoding the Nomenclature Dell SNPDFK3YC/16G

The alphanumeric string "Dell SNPDFK3YC/16G" is the specific identifier for this memory module. Let's break it down:

  • Dell: The manufacturer of the memory module.
  • SNPDFK3YC/16G: This alphanumeric code is a unique identifier for the specific model and capacity of the memory module.

16GB (1X16GB) 2666MHz PC4-21300 CL19 ECC Registered 2Rx8 1.2V DDR4 SDRAM 288-Pin DIMM

This segment of the nomenclature provides a wealth of information about the specifications of the memory module.

  • 16GB (1X16GB): Indicates the capacity of the memory module, which is 16 gigabytes. The "1X16GB" suggests a single 16GB module.
  • 2666MHz: Denotes the memory speed, measured in megahertz (MHz). In this case, the module operates at a speed of 2666MHz.
  • PC4-21300: Refers to the memory type and bandwidth. "PC4" indicates DDR4 technology, and "21300" represents the theoretical maximum bandwidth in megabytes per second (MB/s).
  • CL19: Stands for CAS Latency, a measure of the delay time between the moment a memory controller tells the memory module to access a particular memory column and the moment the data from the given array is available.
  • ECC Registered: Specifies that the memory module has an Error-Correcting Code (ECC) and is registered. ECC helps detect and correct errors in the stored data, enhancing the reliability of the memory.
  • 2Rx8: Indicates the organization of the memory module. "2Rx8" signifies a dual-rank module with eight memory banks.
  • 1.2V: Represents the voltage at which the memory module operates, which is 1.2 volts. This is part of the DDR4 standard, which generally operates at lower voltages compared to its predecessors.
  • DDR4 SDRAM: Identifies the type of memory technology used, which is Double Data Rate 4 Synchronous Dynamic Random Access Memory.
  • 288-Pin DIMM: Describes the physical form factor of the memory module. In this case, it is a Dual Inline Memory Module (DIMM) with 288 pins.

Significance in Server Environments

Now that we've deciphered the nomenclature, let's explore why the Dell SNPDFK3YC/16G is specifically designed for server environments.

Capacity for Server Workloads

With a capacity of 16GB, this memory module is well-suited for handling the demanding workloads typical of server environments. Servers often need to process large datasets and run multiple applications simultaneously, making ample memory crucial for optimal performance.

High Speed for Efficient Operations

The 2666MHz memory speed ensures efficient data transfer and quick access to stored information. This is vital for servers, which need to respond promptly to requests from multiple users or execute complex calculations and processes.

Reliability with ECC

The inclusion of Error-Correcting Code (ECC) is a key feature for servers where data integrity is paramount. ECC helps identify and rectify errors in the stored data, reducing the risk of data corruption and ensuring the reliability of the server.

Registered Design for Stability

The "Registered" attribute in the nomenclature indicates that this memory module is registered. Registered memory modules, as opposed to unbuffered modules, add a register between the memory controller and the RAM modules. This enhances stability and allows for larger amounts of memory to be installed on the server without compromising performance.

Dual-Rank for Enhanced Performance

The "2Rx8" configuration signifies that the memory module is dual-rank with eight memory banks. This organization enhances memory efficiency and can result in improved performance, especially in scenarios where simultaneous access to multiple memory locations is common.

Low Voltage for Energy Efficiency

Operating at a voltage of 1.2V aligns with modern energy-efficient standards. Lower voltage not only contributes to reduced power consumption but also helps in minimizing heat generation, contributing to overall energy efficiency in server environments.

DDR4 Technology for Modern Compatibility

Being DDR4 SDRAM, this memory module is designed with the latest technology, ensuring compatibility with modern server systems. DDR4 has become the standard for new server deployments, offering improved performance and efficiency over its predecessors.

Physical Compatibility with 288-Pin DIMM Slots

The 288-pin DIMM form factor ensures physical compatibility with servers designed to accommodate this type of memory module. This standardized form factor simplifies the upgrading or replacement process for server administrators.

Use Cases and Applications

The Dell SNPDFK3YC/16G memory module is tailored for server applications where performance, reliability, and stability are critical. Here are some specific use cases where this memory module excels:

Data Centers

In large-scale data center environments, where numerous servers work together to process and store vast amounts of data, the Dell SNPDFK3YC/16G can contribute to the seamless operation of applications and services.


Servers used for virtualization, running multiple virtual machines concurrently, require substantial memory resources. The 16GB capacity and ECC support make this memory module well-suited for virtualized environments.

Database Servers

Database servers, responsible for handling and retrieving data for various applications, benefit from the high-speed capabilities and ECC features of this memory module, ensuring data integrity and swift access.

Enterprise Applications

For enterprises running resource-intensive applications such as ERP (Enterprise Resource Planning) software or CRM (Customer Relationship Management) systems, the Dell SNPDFK3YC/16G provides the necessary performance and reliability.

Cloud Computing Infrastructure

In cloud computing environments, where servers cater to diverse workloads and user demands, the attributes of this memory module contribute to the overall efficiency and responsiveness of the cloud infrastructure.


Ensuring proper compatibility is crucial to maximizing the benefits of the Dell SNPDFK3YC/16G memory module.

Compatibility with Dell Servers

As a Dell-branded product, this memory module is designed and tested for compatibility with Dell servers. Before purchase, it is essential to verify that the specific Dell server model is listed in the compatibility documentation.


The 288-pin DIMM form factor is a standard in many server configurations. However, it is imperative to check the server's documentation to confirm the supported memory configurations and DIMM slot population rules.

Population Guidelines

Server memory performance can be affected by how memory modules are populated across DIMM slots. Following the manufacturer's guidelines for population, especially in terms of ranks and channels, ensures optimal performance.

Firmware and BIOS Updates

Before installing new memory modules, checking and updating the server's firmware and BIOS is recommended. This ensures that the server is equipped to recognize and utilize the features of the DDR4 memory module.
