Product Description
The HP FS376AA is a 4GB Fully Buffered DIMM (FB-DIMM) memory module operating at DDR2 speeds of 800MHz. FB-DIMMs were a technology developed to overcome the limitations of traditional unbuffered and registered DIMMs, particularly in high-density server configurations. They feature an Advanced Memory Buffer (AMB) chip on the module itself, which serializes and deserializes data, effectively isolating the memory controller from the DRAM chips. This allows for higher memory speeds and greater module density without overwhelming the memory controller. The 2Rx4 configuration indicates a dual-rank module, with each rank using x4 (4-bit-wide) DRAM chips. This configuration, combined with the FB-DIMM architecture and a CAS Latency (CL) of 5, provides a balance of capacity, speed, and timing suitable for demanding server workloads. The 800MHz speed (PC2-6400F) represents the higher end of DDR2 performance. This 4GB DDR2-800MHz FB-DIMM is designed for servers and workstations that specifically support the FB-DIMM form factor, often found in older generations of enterprise hardware. FB-DIMMs generate more heat than standard DIMMs due to the AMB chip, and systems designed for them typically have enhanced cooling solutions. This module is crucial for systems requiring significant memory capacity and bandwidth, such as those running virtualization, databases, or complex scientific applications.
