Product Description
The HP PP639AV memory kit provides a total of 1GB of high-performance RAM, distributed across two 512MB Registered DIMM (RDIMM) modules. This configuration is specifically engineered for server and workstation environments where stability, reliability, and data integrity are paramount. The DDR2 technology operating at a speed of 400MHz ensures efficient data transfer rates, contributing to overall system responsiveness and performance. Each module in the PP639AV kit features a 1Rx8 rank configuration, indicating a single rank with eight memory banks. This design is optimized for compatibility with a wide range of server chipsets. Furthermore, the RDIMM form factor includes an onboard register that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory densities and improved signal integrity, which is crucial in multi-processor systems. Crucially, these modules support ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, preventing errors from propagating through the system and potentially causing crashes or data loss. The CL3 CAS latency indicates the number of clock cycles required to access a particular memory column. This kit is an ideal upgrade for HP servers and workstations that require dependable, error-corrected memory for demanding enterprise applications.
