Description
The Apacer 78.B1GA1.42B is a 4GB DDR2 Registered DIMM (RDIMM) memory module, engineered for server and workstation environments that require enhanced stability and performance. Operating at a speed of 667MHz (equivalent to PC2-5300R), this module provides a significant boost in memory capacity and responsiveness for demanding applications. The Registered DIMM configuration includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved signal integrity. This specific module features a 2Rx4 rank configuration, indicating it is dual-rank with each rank utilizing x4 data width. This configuration can offer performance benefits in certain memory access patterns compared to single-rank modules. Furthermore, it supports ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors in memory, crucial for maintaining data integrity in critical systems like servers and high-performance workstations. With a CAS Latency (CL) of 5, the Apacer 78.B1GA1.42B strikes a balance between speed and stability. This memory module is designed to meet the rigorous demands of enterprise computing, ensuring reliable operation and efficient multitasking. It is an ideal upgrade or replacement component for systems that utilize DDR2 RDIMMs and require dependable memory performance.
