Description
The Sun X4063A memory kit provides a substantial 8GB of capacity, distributed across two 4GB Registered DIMM modules. This configuration is specifically engineered for server environments and workstations that demand high reliability and performance. The DDR2 technology, clocked at 667MHz, offers a significant improvement in data transfer rates over previous generations, making it suitable for memory-intensive tasks such as virtualization, database management, and complex simulations. The RDIMM form factor includes an onboard register that buffers data 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 and improving signal integrity, which is crucial for system stability in high-density memory configurations. The 2Rx4 designation indicates that each module is dual-rank with an x4 data width per DRAM chip, further optimizing performance and capacity. Error-Correcting Code (ECC) functionality is integrated into these modules, enabling the detection and correction of single-bit memory errors. This feature is paramount in mission-critical applications where data integrity is non-negotiable, preventing system crashes and data corruption. With a CAS Latency of CL5, the modules strike a balance between speed and stability, ensuring efficient operation within compatible server platforms.
