Product Description
The 78P0639 IBM 16GB DDR3 1066MHz CL7 ECC VLP RDIMM Memory module provides high-capacity server memory designed to maintain data integrity with ECC functionality. It is typically deployed in IBM server environments requiring reliable and scalable memory solutions. This Registered DIMM (RDIMM) operates at a clock speed of 1066MHz and utilizes a CAS latency of 7, balancing speed and latency for server workloads. The Very Low Profile (VLP) form factor aids in optimizing space within dense server chassis. Key Features 16GB memory capacity DDR3 technology at 1066MHz frequency CAS Latency of 7 (CL7) for memory timing Error-Correcting Code (ECC) support to enhance data reliability Registered DIMM architecture with Very Low Profile (VLP) form factor This memory module serves a critical role in server performance, supporting error detection and correction to reduce data corruption risks. Its VLP design makes it suitable for systems where space constraints exist without compromising memory capacity.

Use Cases
This memory module is typically used in IBM server systems requiring stable and error-corrected memory performance. It fits environments such as data centers and enterprise IT infrastructures where space efficiency and memory reliability are important. How It's Used: Installed in IBM servers to expand system memory to 16GB per module Utilized in dense rack servers where VLP modules enable better airflow and higher memory density Deployed in enterprise applications needing ECC memory to detect and correct data errors Used in workloads with moderate memory bandwidth demands at 1066MHz speed Employed in configurations requiring Registered DIMMs for signal integrity Overall, this RDIMM module provides a balance of capacity, reliability, and form factor that supports server operations where memory integrity and density are essential without assuming unsupported compatibility or performance benefits.

FAQ's
What does ECC mean in this memory module? ECC stands for Error-Correcting Code, a feature that detects and corrects common types of data corruption, improving memory reliability in server environments. Is the 78P0639 compatible with all IBM servers? Compatibility depends on the specific server model and its memory specifications. The 78P0639 is designed for IBM servers that support 16GB DDR3 1066MHz ECC RDIMMs with VLP form factor. What is the significance of the 1066MHz frequency? The 1066MHz speed indicates the data transfer rate of the DDR3 memory, balancing bandwidth and latency for certain server workloads without implying compatibility with faster or slower memory types. How does the Very Low Profile (VLP) design affect installation? VLP modules have a reduced height compared to standard DIMMs, allowing installation in servers with limited vertical space and supporting higher memory module density. What does CL7 latency indicate? CL7 refers to the CAS latency, which is the delay time between the memory controller requesting data and when it is available, with lower values representing shorter delays within the DDR3 specification. Can this memory be used in non-IBM systems? The 78P0639 is specifically designed for IBM servers. Using it in other systems requires verifying compatibility with the motherboard and supported memory types.
