Product overview for the Hynix HMA41GR7MFR4N-TF

In the realm of computer hardware, the Hynix HMA41GR7MFR4N-TF 8GB 2133MHz PC4-17000 ECC Registered CL15 Single Rank X4 1.2V DDR4 SDRAM 288-Pin RDIMM Memory Module stands out as a crucial component, specifically designed for servers. This comprehensive guide aims to break down the specifications and functionalities of this memory module in simple English, making it accessible to both tech enthusiasts and those new to the field.

Unpacking the Terminology
  • Hynix: This refers to the manufacturer, Hynix Semiconductor Inc., a major player in the global semiconductor industry.
  • HMA41GR7MFR4N-TF: This alphanumeric string is a unique identifier for this particular memory module. It's essential for differentiating between various models and specifications.
2133MHz PC4-17000
  • 2133MHz: This indicates the clock speed of the memory module, measured in megahertz (MHz). A higher clock speed generally means faster data transfer.
  • PC4-17000: The PC4 designation signifies that it is a DDR4 memory module. The number 17000 represents the theoretical maximum data transfer rate in megabytes per second (MB/s).
ECC Registered CL15
  • ECC (Error-Correcting Code): ECC is a type of memory that can detect and correct common data corruption errors, crucial for maintaining data integrity in critical computing environments.
  • Registered (Buffered): This indicates that the module uses a register to control the flow of data within the memory. It enhances stability and reliability but may introduce slight latency.
  • CL15: CAS Latency (CL) is the time it takes between a command being sent to the memory and the first piece of data being available. A CL15 latency is a measure of the module's speed, where lower values are generally better.
Single Rank X4
  • Single Rank: In memory modules, ranks are logical subdivisions, and a single rank module has memory chips on only one side of the module. This can impact performance in certain scenarios.
  • X4: Indicates the organization of the memory chips on the module. In this case, it means that each memory chip is a 4-bit chip.
  • 1.2V: The operating voltage of the module. Lower voltage generally implies better energy efficiency.
  • DDR4 SDRAM: DDR4 is the fourth generation of Double Data Rate Synchronous Dynamic Random Access Memory, offering improvements in speed and efficiency compared to its predecessors.
  • 288-Pin RDIMM: The number of pins on the memory module's connector. RDIMM stands for Registered DIMM, and the 288 pins are crucial for connecting and transferring data between the memory and the motherboard.
Memory Module for Server
  • Server Compatibility: This memory module is specifically designed for use in servers, where reliability, stability, and data integrity are of utmost importance.
Key Features and Benefits
  • The 2133MHz clock speed ensures fast data transfer, making it suitable for demanding server applications.
Error Correction for Data Integrity
  • ECC capability aids in detecting and correcting errors, critical for maintaining the accuracy of data in server environments.
Stability with Registered (Buffered) Design
  • The registered design enhances stability by controlling the flow of data, ensuring a reliable and consistent performance.
Optimized for Server Environments
  • Tailored for server use, this module meets the stringent requirements of server applications where performance, stability, and data integrity are non-negotiable.
Understanding Clock Speed and Performance

The clock speed, in this case, 2133MHz, plays a pivotal role in determining how quickly the memory can send and receive data. For server applications, a higher clock speed is often desirable as it directly correlates with faster data processing. This is particularly important in scenarios where large datasets need to be quickly accessed and manipulated.

The Significance of ECC in Server Memory

In server environments, data corruption can have severe consequences. ECC memory, a feature of this Hynix module, provides an additional layer of protection by detecting and correcting common errors that may occur during data storage or transmission. This feature is especially crucial in critical applications such as financial transactions, scientific computations, and data centers.

Registered (Buffered) Design for Stability

The registered or buffered design of this memory module contributes to system stability. Using a register to manage the flow of data between the memory and the memory controller, it helps prevent data errors and ensures a more reliable performance. While this may introduce a slight latency compared to unbuffered memory, the trade-off is often worthwhile in server environments where stability is paramount.

Single Rank Configuration and Its Implications

This memory module is classified as a single rank, indicating that the memory chips are located on one side of the module. Single-rank modules often have slightly better performance in certain applications compared to dual-rank or quad-rank modules. However, the impact of rank configuration depends on the specific workload and usage scenario.

Power Efficiency with 1.2V Operating Voltage

The 1.2V operating voltage of this DDR4 memory module contributes to its energy efficiency. Lower voltage not only reduces power consumption but also minimizes heat generation, a crucial factor in server rooms where maintaining an optimal operating temperature is essential for the overall system's health.

DDR4 Advancements for Improved Performance

As a DDR4 SDRAM module, this Hynix memory takes advantage of the advancements introduced in the DDR4 standard. Compared to its predecessor, DDR3, DDR4 offers higher data transfer rates, improved reliability, and increased capacity. These improvements collectively contribute to a better overall system performance.


The 288-pin RDIMM form factor ensures compatibility with server motherboards designed to accommodate DDR4 memory modules. It is essential to verify the compatibility of this module with the specific server hardware.
