Hynix HYMP512B72BP8N2-C4 AB-A 1GB DDR2-533MHz ECC Fully Buffered CL4

Product Description

The Hynix HYMP512B72BP8N2-C4 is a 1GB memory module specifically designed for server and high-end workstation platforms that utilize FB-DIMM (Fully Buffered DIMM) technology. This type of memory is characterized by an Advanced Memory Buffer (AMB) chip on the module, which serializes data traffic between the memory controller and the DRAM devices. This buffering mechanism significantly increases memory bandwidth and allows for higher memory densities and speeds compared to traditional Unbuffered DIMMs (UDIMMs). Operating at a speed of 533MHz (often referred to as PC2-4200), this DDR2 module provides substantial performance for memory-intensive applications. The CAS Latency (CL) of 4 indicates the number of clock cycles required to access a particular column in a row. The 2Rx8 configuration signifies that the module has two ranks, each with eight memory chips, which can improve performance by allowing the memory controller to interleave accesses across different ranks. FB-DIMMs were a transitional technology, primarily used in server platforms like certain Intel Xeon and AMD Opteron systems, before the widespread adoption of DDR3 and later memory standards. They offered advantages in scalability and bandwidth but also generated more heat due to the AMB chip. This Hynix module represents a reliable component for systems that require this specific type of memory for optimal operation.
