Description
This 4GB DDR2 RDIMM from Atp, identified by SKU AB12L72P4SMB0S, is a memory module engineered for server and workstation platforms that utilize DDR2 memory technology. The RDIMM designation indicates the presence of a register chip on the module, which buffers command and address signals. This buffering reduces the electrical load on the memory controller, enabling higher memory configurations and improving overall system stability, particularly in dense memory setups. The module operates at a frequency of 667MHz, corresponding to the PC2-5300 standard, with a CAS Latency of CL5. This provides a balance of speed and responsiveness suitable for various server workloads. The 2Rx4 organization signifies a dual-rank configuration, where each rank is composed of four data chips, which can enhance performance by allowing for more parallel access to memory. As a component designed for enterprise environments, it includes ECC (Error-Correcting Code) functionality. ECC memory is crucial for detecting and correcting single-bit errors, thereby preventing data corruption and ensuring the high level of reliability required for continuous server operations. The standard 1.8V operating voltage is typical for DDR2 memory modules.
