Hynix HYMP112S64CP8-Y5 AB 1GB DDR2-667MHz non-ECC Unbuffered CL5

Product Description

The Hynix HYMP112S64CP8-Y5 AB is a 1GB DDR2 SODIMM memory module, designed for laptops and other portable computing devices that were prevalent during the DDR2 era. DDR2 SDRAM offered improvements over DDR1 in terms of speed and efficiency, and this module represents a common capacity and speed configuration for that generation of memory technology. The 1GB capacity was a significant upgrade for many systems when it was introduced, allowing for smoother multitasking and better performance in applications of the time. This module operates at a frequency of 667MHz, which corresponds to a PC2-5300 data transfer rate (5300 MB/s). It features a CAS Latency (CL) of 5, indicating the number of clock cycles required to access data. The 128Mx64 configuration specifies that the module contains 128 million by 64 bits of memory. It is unbuffered, meaning data signals are passed directly to the memory chips without an intermediate buffer, which is standard for SODIMMs in consumer laptops. Furthermore, it is Non-ECC (Non-Error-Correcting Code), meaning it lacks the circuitry to detect and correct memory errors, which is typical for most consumer-grade memory modules. The standard operating voltage for DDR2 memory is 1.8V. This module is suitable for upgrading or replacing memory in older laptops, netbooks, or other small form factor PCs that specifically require DDR2 SODIMM modules. While DDR2 technology is now considered legacy, modules like the HYMP112S64CP8-Y5 remain essential for maintaining and operating older hardware. Its specifications make it a reliable component for systems designed to run operating systems and applications from the mid-2000s.
