Description
The ATP AB56L72Z4BFB3M is a 2GB Registered Dual In-line Memory Module (RDIMM) operating at DDR-333MHz speeds, also known as PC2700. Registered DIMMs include a register chip that buffers command and address signals between the memory controller and the DRAM chips. This buffering reduces electrical load on the memory controller, allowing for more memory modules to be installed on a single channel and supporting higher memory capacities, which is crucial for server environments. This module features Error-Correcting Code (ECC) functionality, which detects and corrects single-bit memory errors, and detects multi-bit errors. ECC memory is essential for mission-critical applications where data integrity is paramount, such as in servers, workstations, and other enterprise-grade computing systems. The 2Rx4 configuration indicates that the module is dual-ranked and uses x4 (4-bit) DRAM chips, which can offer performance benefits in certain system architectures. With a CAS Latency (CL) of 2.5, this memory module provides a balance between speed and stability. The 184-pin connector is standard for DDR DIMMs. The ATP AB56L72Z4BFB3M is designed to enhance the performance and reliability of server and workstation systems that require robust memory solutions for demanding workloads and large datasets.
