Hynix HYMP564S64EP6-Y5 AB-C 512MB DDR2-533MHz non-ECC Unbuffered

Description

The Hynix HYMP564S64EP6-Y5 AB-C is a 512MB DDR2 SODIMM memory module, designed for use in laptops and other compact computing devices that support the DDR2 standard. DDR2 memory offered improvements in bandwidth and power efficiency over the previous DDR generation, and this module represents a common capacity and speed for systems from the mid-2000s. A 512MB capacity was a typical upgrade size, providing a noticeable performance improvement for multitasking and running applications of that era. This module operates at a frequency of 533MHz, which corresponds to the PC2-4200 data transfer rate (4200 MB/s). It features a CAS Latency (CL) of 4, indicating the number of clock cycles required for the memory controller to access a specific column in a row. The 64Mx64 configuration signifies that the module contains 64 million bits organized in 64-bit data width. As a standard SODIMM for consumer laptops, it is unbuffered, meaning data signals are passed directly to the memory chips. It is also Non-ECC (Non-Error-Correcting Code), lacking the error detection and correction capabilities found in server-grade memory. The standard operating voltage for DDR2 memory is 1.8V. This module is suitable for upgrading or replacing memory in older laptops or small form factor PCs that specifically require DDR2 SODIMM modules. It is crucial to ensure compatibility, as DDR2 memory is physically and electrically incompatible with DDR, DDR3, DDR4, and DDR5 memory standards. The Hynix HYMP564S64EP6-Y5 AB-C is a component for maintaining older hardware, providing essential memory for systems designed to run software from the period when DDR2 was the mainstream memory technology.
