Description
This IBM memory module, identified by SKU 43X6044, provides 1GB of DDR3 RAM, specifically designed and tested for compatibility with IBM server systems. It operates at a speed of 1333MHz, which was a common and reliable speed for DDR3 memory in enterprise environments, ensuring efficient data access for various applications. The CL9 CAS latency indicates a moderate response time, suitable for general server operations. The module is a Registered DIMM (RDIMM), which incorporates an onboard register chip. This register buffers command and address signals, reducing the electrical load on the memory controller. This design is crucial for enabling higher memory capacities and enhancing system stability, particularly in multi-processor or densely populated server configurations common in IBM's server lines. With its 1GB capacity and DDR3 technology, this IBM RDIMM is suitable for maintaining or upgrading the memory in compatible IBM servers. It is designed to meet the memory requirements for operating systems, applications, and workloads typical of the DDR3 era, ensuring reliable performance for business-critical tasks.
