HP KN197AV 2GB Kit (2x1GB) DDR2-667MHz FB-DIMM 2Rx8 CL5 Memory

Description

The HP KN197AV is a 2GB memory kit consisting of two 1GB DDR2 Fully Buffered DIMM (FB-DIMM) modules, operating at a speed of 667MHz (PC2-5300F). This memory configuration is specifically designed for servers and workstations that utilize the FB-DIMM technology, which was prevalent in certain generations of enterprise hardware. FB-DIMMs feature an Advanced Memory Buffer (AMB) chip on each module, which serializes data transfers between the memory controller and the DRAM chips. This buffering mechanism allows for higher memory speeds and greater module density, while also reducing the electrical load on the memory controller. Each 1GB module in this kit is a 2Rx8 configuration (Dual Rank x8), meaning it has two ranks of memory chips, with each rank consisting of eight data lines. This configuration can improve performance by allowing the memory controller to access data from different ranks concurrently. The modules support Error-Correcting Code (ECC), which is essential for server environments as it detects and corrects common memory errors, thereby enhancing system stability and data reliability. The CAS Latency is CL5, which is typical for DDR2-667MHz modules. With a standard operating voltage of 1.8V, the HP KN197AV kit provides a reliable memory upgrade for compatible server platforms. While DDR2 and FB-DIMM technology are older standards, this kit remains relevant for maintaining or upgrading legacy server systems. The dual-module configuration ensures that users receive matched pairs, which is often recommended for optimal performance and stability in dual-channel or multi-channel memory architectures found in servers.
