Product Description
The Hynix HYMP125F72CP8D3-S5-AB is a 2 Gigabyte memory module belonging to the DDR2 generation of Synchronous Dynamic Random-Access Memory (SDRAM). This specific module utilizes the FB-DIMM (Fully Buffered DIMM) form factor, which incorporates an Advanced Memory Buffer (AMB) chip on the module itself. The AMB chip serializes data transfers between the memory controller and the DRAM chips, enabling higher memory bandwidth and allowing for more memory modules to be installed on a single memory channel compared to traditional unbuffered DIMMs, albeit often at the cost of increased latency and power consumption. Operating at a clock speed of 800 MHz (often referred to as PC2-6400), this module provides a substantial data transfer rate suitable for memory-intensive applications commonly found in servers and high-end workstations. The CAS Latency (CL) is rated at 6 clock cycles, indicating the number of clock cycles it takes for the memory module to respond to a column address strobe command. The configuration of 2R x 8 signifies that the module has two physical ranks of DRAM chips, each organized as 8 bits wide, which affects how the memory controller accesses data on the module. This 2GB DDR2 FB-DIMM is designed for systems that specifically support this type of memory technology. FB-DIMMs were prevalent in server platforms during the DDR2 era, offering a pathway to increased memory capacity and bandwidth. Users should verify system compatibility, as DDR2 FB-DIMMs are not interchangeable with DDR2 UDIMMs or other memory generations like DDR3 or DDR4.
