Hynix HYMP512F72BP8N2-Y5-AC 1GB DDR2-667MHz FB-DIMM 2Rx8 CL5 Memory

Description

This Hynix memory module, identified by SKU HYMP512F72BP8N2-Y5-AC, is a 1GB DDR2 Fully Buffered DIMM (FB-DIMM). FB-DIMMs were a server memory technology that aimed to overcome the limitations of traditional DIMMs by introducing an Advanced Memory Buffer (AMB) chip on each module. This buffer chip handles command and address signals, effectively decoupling the memory modules from the memory controller and allowing for higher memory speeds and densities. The module operates at a frequency of 667MHz, which was considered a high speed for DDR2 memory. It features a 2Rx8 configuration, meaning it is dual-ranked with eight memory chips per rank. This configuration can offer performance benefits in certain server applications by allowing for more efficient interleaving of memory accesses. The CL5 latency indicates the number of clock cycles required for column access, a key factor in memory performance. As an FB-DIMM, this module includes the characteristic AMB chip, which requires additional power and generates more heat than standard DIMMs. Despite these considerations, FB-DIMMs enabled significant advancements in server memory capacity and performance during their era. This specific module is suitable for servers and workstations that are designed to utilize DDR2 FB-DIMM technology.
