Hynix HYMP151F72CP4N3-Y5-D 4GB DDR2-667MHz FB-DIMM 2Rx4 CL5 Memory

Product Description

This Hynix memory module, identified by the part number HYMP151F72CP4N3-Y5-D, is a 4GB Fully Buffered DIMM (FB-DIMM) designed for server and workstation environments. It operates at DDR2 speeds of 667MHz, providing a significant memory capacity for systems that require it. The FB-DIMM architecture includes an Advanced Memory Buffer (AMB) chip on each module, which serializes data traffic between the memory controller and the DRAM chips. This design allows for higher memory densities and speeds compared to traditional unbuffered DIMMs, though it also increases latency slightly. The module features a 2Rx4 configuration, meaning it has two ranks, each with four data chips per rank. This configuration is common for higher-capacity FB-DIMMs and contributes to its overall performance profile. The CAS Latency is rated at CL5, which is typical for DDR2-667 modules. Like most server-grade memory, this FB-DIMM also supports ECC (Error-Correcting Code) functionality, which is crucial for detecting and correcting memory errors to ensure system stability and data integrity. FB-DIMMs were a transitional technology, primarily used in servers and workstations during the DDR2 era, before DDR3 and subsequent technologies became prevalent. Systems that utilize this specific type of memory, such as certain Intel Xeon and AMD Opteron platforms, benefit from the increased bandwidth and capacity that FB-DIMMs offer. This Hynix module is a reliable component for maintaining or upgrading such systems.
