Product Description
The Hynix HYMP512F72BP8D2-Y5 is a 1GB memory module built on the FB-DIMM (Fully Buffered DIMM) platform, designed to deliver enhanced performance and reliability for server and workstation systems. This module operates at a faster DDR2 speed of 667MHz, corresponding to PC2-5300 specifications, which allows for greater data throughput compared to lower-speed DDR2 modules. The FB-DIMM architecture, with its integrated Advanced Memory Buffer (AMB), serializes data transfers, enabling higher memory capacities and improved signal integrity, especially in systems with multiple memory modules. This specific module is configured as 2Rx8, indicating it uses two ranks of memory chips, each with an 8-bit data width. This dual-rank configuration can contribute to improved performance in certain server workloads by allowing the memory controller to access data from different ranks concurrently. The CAS Latency (CL) is set at 5 clock cycles, which is a standard latency for DDR2-667MHz modules, balancing speed and stability. Crucially, the HYMP512F72BP8D2-Y5 includes ECC (Error-Correcting Code) functionality. ECC memory is essential in mission-critical environments like servers, as it automatically detects and corrects memory errors, thereby preventing data corruption and enhancing system stability. This Hynix module is intended for motherboards that specifically support DDR2 FB-DIMMs, offering a reliable upgrade or replacement option for systems requiring robust memory performance and data integrity.
