Product Description
This IBM FC7894 module represents a 2GB DDR2 SDRAM memory component, specifically designed for systems that utilize the Continuity DIMM (CDIMM) form factor. Operating at a frequency of 533MHz, which corresponds to a PC2-4200 bandwidth, it offers a significant upgrade for older server and workstation platforms that are compatible with DDR2 technology. The CDIMM form factor is often used in specific server architectures, sometimes in conjunction with other memory modules, to maintain system continuity or enable specific configurations. The module's 2Rx4 organization indicates a dual-rank configuration utilizing x4 DRAM devices. This setup can enhance performance by allowing the memory controller to access different memory banks in parallel, improving data throughput. The low CAS Latency of CL4 contributes to faster response times, which is critical for applications sensitive to memory access delays. As a component often found in server environments, it is expected to support ECC (Error-Correcting Code) functionality, which is essential for detecting and correcting memory errors to ensure data integrity and system stability. With a standard DDR2 voltage of 1.8V, the IBM FC7894 is built to meet the specifications of its generation. It serves as a reliable option for expanding the memory capacity of compatible IBM servers or other systems that require this specific type of memory module. Its specifications are tailored for environments where consistent performance and data accuracy are crucial, making it a valuable component for maintaining and upgrading legacy enterprise hardware.
