SK hynix HYMP512F72BP8D2-Y5 1Gb Ddr2 667Mhz Ecc Fully Buffered Cl5 1.8V Dual Rank

Hynix 1Gb DDR2 fully buffered module

This 1Gb DDR2 module operates at 667MHz with CL5 latency and ECC protection. It uses a fully buffered architecture at 1.8V and is organised as a dual-rank 72-bit device. The PC2-5300 rating identifies its standard data-rate class. It suits maintenance of legacy servers and workstations that require registered ECC memory.

Sustained-load behaviour

Under continuous operation the registered buffer reduces electrical loading on the memory controller. ECC corrects single-bit errors without halting the system. Dual-rank organisation allows the controller to interleave accesses for steadier throughput. The 1.8V supply keeps power draw predictable during long runs. It is not for platforms that need unbuffered non-ECC DIMMs or higher-density modules.
