Product Description
The 47J0139 IBM 16GB DDR3 1066MHz CL7 ECC RDIMM Memory module is designed to provide system memory expansion for compatible IBM servers. It operates at a frequency of 1066MHz with a CAS latency of 7, offering a balance of speed and responsiveness typical for DDR3 memory in enterprise environments. This memory module incorporates Error-Correcting Code (ECC) functionality, which detects and corrects common types of internal data corruption, enhancing system stability. The Registered DIMM (RDIMM) design adds buffering to improve signal integrity and scalability in multi-module server configurations. Key Features 16GB capacity DDR3 memory module 1066MHz clock speed with CL7 latency ECC support for error detection and correction Registered DIMM architecture for improved signal integrity Compatible with IBM server platforms This memory module is particularly valuable in servers requiring reliable error handling and stable memory performance under heavy workloads. Its registered design supports higher memory densities and better signal quality, suitable for enterprise IT infrastructure.

Use Cases
This memory module is typically used in IBM server systems where stable and error-correcting memory is critical. It suits data center environments and enterprise applications requiring consistent memory performance and integrity during demanding workloads. How It's Used: Expanding memory capacity in IBM x86 and POWER servers Supporting database servers requiring ECC protection Enhancing virtualization hosts with reliable RAM modules Deploying in enterprise applications with multi-processor configurations Replacing or upgrading existing 16GB DDR3 ECC RDIMM modules in IBM servers By maintaining data integrity and improving memory stability, this module helps servers deliver consistent operation during critical tasks. It plays a key role in infrastructure where memory errors can impact system availability.

FAQ's
What does ECC stand for in this memory module? ECC stands for Error-Correcting Code. It allows the memory to detect and correct common data corruption, which improves system reliability in server environments. Is this 16GB DDR3 module compatible with all IBM servers? This module is designed for specific IBM server platforms supporting DDR3 1066MHz ECC Registered DIMMs. Compatibility depends on the server model and its memory specifications. What is the significance of CL7 latency? CL7 indicates the CAS latency of 7 clock cycles, which specifies the delay between memory request and data availability. It affects the memory's response time at 1066MHz speed. Can this RDIMM be used in non-registered DIMM slots? No, Registered DIMMs require compatible server memory controllers and slots designed for RDIMM modules; they are not interchangeable with unbuffered DIMMs. Does the 47J0139 memory support multi-processor servers? Yes, the Registered DIMM design supports better signal integrity, making it suitable for multi-processor server configurations common in IBM enterprise systems. What frequency does this memory operate at? This memory module operates at 1066MHz, a standard speed for DDR3 server memory balancing performance and compatibility.
