Hynix HYMP564R728-E3 AA-A 512MB DDR2-400MHz ECC Registered CL3

Product Description

The Hynix HYMP564R728-E3 AA-A is a 512MB memory module engineered for high-reliability computing platforms such as servers and workstations. It utilizes DDR2 SDRAM technology, operating at a clock speed of 400MHz, which corresponds to a PC2-3200 data transfer rate. This module is specifically designed as an ECC (Error-Correcting Code) Registered DIMM. The ECC functionality allows the memory system to detect and correct single-bit errors on the fly, significantly enhancing data integrity and system stability, which is critical for mission-critical applications and continuous operation. The 'Registered' aspect of this DIMM, also known as buffered memory, means that the command and address signals are buffered by registers on the module itself. This reduces the electrical load on the memory controller, allowing for more memory modules to be installed in a system and enabling higher memory capacities and frequencies. The CAS Latency (CL) is rated at 3, indicating the number of clock cycles it takes for the memory to respond to a column address command. This timing is typical for DDR2 memory operating at this speed. This Hynix memory module is a component designed to meet the rigorous demands of server environments where uptime and data accuracy are paramount. Its 512MB capacity, combined with ECC and registered architecture, makes it suitable for upgrading or populating memory in compatible server motherboards and high-performance workstations. The HYMP564R728-E3 AA-A part number signifies a specific configuration and revision of this memory module, ensuring compatibility with systems that require these precise specifications.
