Product Overview of the IBM 00NU400

The IBM 00NU400 is a high-quality DDR4 SDRAM memory module designed for server use. With a capacity of 16GB, this memory module is ideal for use in enterprise-level servers that require reliable and efficient performance. The module operates at a clock speed of 2133MHz, providing fast data transfer rates, and features Registered technology to improve signal integrity and stability. This article will provide a detailed explanation of the features and specifications of the IBM 00NU400 memory module, including its capacity, clock speed, CAS latency, rank, pin configuration, and LP (low profile) design, as well as its suitability for server use.

Capacity and Clock Speed

The IBM 00NU400 memory module has a capacity of 16GB, which means it can store a significant amount of data. This makes it suitable for memory-intensive applications such as virtualization, data analytics, and database management, which are commonly used in server environments. The module operates at a clock speed of 2133MHz, which refers to the speed at which data is transferred between the memory module and the processor. A higher clock speed means faster data transfer rates, resulting in improved overall system performance.

CAS Latency

The CAS latency, or CL, is an important parameter that determines the timing of data transfer between the memory module and the processor. The IBM 00NU400 memory module has a CAS latency of 15, which means that it takes 15 clock cycles for data to be accessed after a read command is issued. Lower CAS latency values indicate faster data access times, resulting in better system performance. However, CAS latency is just one of many factors that affect overall system performance, and the optimal value may vary depending on the specific server application and workload.

Registered Technology

The IBM 00NU400 memory module features Registered technology, which includes a register or buffer that helps to improve the signal integrity and stability of the memory subsystem. Registered memory modules are commonly used in server environments where multiple memory modules are installed, as they help to reduce the electrical load on the memory controller and ensure reliable operation. The Registered technology used in the IBM 00NU400 module adds an extra layer of protection to the server's memory subsystem, making it suitable for use in mission-critical applications that require high levels of reliability and stability.

Dual Rank

The IBM 00NU400 memory module is Dual Rank, which refers to the organization of memory chips on the module. Dual Rank memory modules have two sets of memory chips, organized into two ranks, which can be accessed independently. This allows for better memory utilization and improved performance, particularly in applications that require simultaneous access to multiple memory locations. Dual Rank memory modules are a popular choice for server environments, as they provide a good balance between performance and capacity.

DDR4 SDRAM and 288-Pin RDIMM

The IBM 00NU400 memory module uses DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random Access Memory) technology, which is the latest generation of DDR memory. DDR4 SDRAM provides faster data transfer rates and improved power efficiency compared to DDR3 memory, making it well-suited for modern server environments. The 288-Pin RDIMM (Registered DIMM) form factor of the IBM 00NU400 module is a standard form factor used in most server systems. The 288 pins on the module provide a high-speed interface for data transfer between the memory module and the server's memory controller.
