Memory as the Server's Brain

In a server, memory acts as the brain of the system. It stores data that the server is actively using, providing quick and reliable access to this information. When data is requested by the CPU or other components, it's retrieved from memory, which is significantly faster than accessing data from slower storage devices like hard drives.

Handling Multitasking

Servers are designed to handle multiple tasks simultaneously, serving requests from various users or applications. Having ample memory allows a server to store data and application code for these tasks, ensuring smooth operation and responsiveness.

Data Integrity and Reliability

In a server environment, data integrity is paramount. Servers are often used for mission-critical applications where data loss or corruption is unacceptable. ECC memory, like the one in our product name, is designed to detect and correct memory errors, contributing to data reliability.

Scalability

Server memory needs to be scalable. As the demands on a server increase, it should be possible to expand the memory capacity to handle the additional load. The 370-AHJZ 128GB module, with its 128GB capacity, provides a substantial base for memory expansion.

Now that we've explored the importance of memory in servers, let's take a closer look at the specifications of the 370-AHJZ 128GB ECC Registered DDR4 memory module.

128GB Capacity

The most prominent feature of this memory module is its large capacity of 128 gigabytes. This is a significant amount of memory, particularly for server applications. With 128GB at its disposal, a server can handle extensive data storage and retrieval tasks efficiently. This is particularly important for applications that require substantial memory, such as virtualization, large databases, and data analytics.

2x64GB Configuration

The 370-AHJZ module achieves its 128GB capacity through a 2x64GB configuration. In other words, it consists of two individual 64GB modules. This configuration is not only about achieving the total capacity but also provides flexibility. Server administrators can easily upgrade or replace individual modules without needing to replace the entire set, making maintenance and scalability easier.

3200 MHz Speed

The module operates at a speed of 3200 MHz. The speed of memory is often a critical factor in server performance. A higher MHz value indicates faster data transfer rates and better overall system responsiveness. While 3200 MHz is not the highest speed available, it still provides excellent performance for a wide range of server applications.

PC4-25600 Bandwidth

The PC4-25600 specification refers to the peak bandwidth of the memory module. In this case, it can transfer data at a rate of 25,600 megabytes per second. This bandwidth is crucial for tasks that require fast data access and transfer, such as virtual machine management and database operations. The high bandwidth ensures that the server can efficiently handle these tasks.

CAS Latency (CL24)

CAS Latency (CL) is a measure of how many clock cycles it takes for data to be available from the memory after a read command is issued. A lower CL value implies better memory performance. CL24 is a moderate latency and is common for DDR4 memory modules. While lower latencies are desirable for some applications, this latency level provides a good balance between speed and performance for most server tasks.

Error Correction Code (ECC)

The inclusion of Error Correction Code (ECC) is a critical feature in this memory module. ECC memory is essential for servers because it helps detect and correct memory errors. In a server environment, data integrity is non-negotiable, and ECC memory ensures that any errors that occur during data storage or retrieval are corrected, preventing data corruption and system crashes.

Registered Memory

This memory module is labeled as "Registered." Registered memory, often referred to as RDIMM (Registered Dual In-Line Memory Module), is a type of memory module that includes a register between the memory controller and the DRAM (Dynamic Random Access Memory) chips. The register helps in improving memory stability and allows for the use of more memory modules in a server without experiencing signal degradation.

Dual Rank X4

The "Dual Rank X4" designation provides information about how the memory chips are organized on the module. "Dual Rank" indicates that there are two sets of memory chips on the module. Dual Rank memory modules can improve performance in certain scenarios, as they allow for better interleaving of data. "X4" likely refers to the organization of data within each rank, indicating that each rank can access data in 4-bit chunks.

1.2V Voltage

The memory module operates at a voltage of 1.2 volts. This is important for energy efficiency, as lower voltage levels typically result in reduced power consumption and heat generation. For servers that run 24/7, energy efficiency is a significant concern, and memory modules with lower voltage can contribute to overall power savings.

DDR4 Technology

DDR4, or Double Data Rate 4, is the fourth generation of DDR memory technology. It's a significant improvement over its predecessors, offering better performance, higher data transfer rates, and increased power efficiency. DDR4 memory is the standard for modern computing systems, especially in the server domain.

288-pin RDIMM

The "288-pin RDIMM" designation specifies the physical form factor of the memory module. RDIMMs are common in server environments because of their reliability and buffering capabilities. The 288-pin design ensures that the module is physically compatible with the memory slots on the server's motherboard. This design also provides the required electrical connections for communication with the server's memory controller.
