Hynix HYMP512U648-E3 AB-A 1GB DDR2-400MHz non-ECC Unbuffered CL3

Product Description

The Hynix HYMP512U648-E3 AB-A is a 1GB memory module designed for systems that utilize DDR2 SDRAM technology. DDR2 represents a second generation of Double Data Rate Synchronous Dynamic Random-Access Memory, offering improved performance and efficiency over its predecessor, DDR. This specific module operates at a clock speed of 400MHz, which translates to a data transfer rate of PC2-3200, indicating its bandwidth capability. The CAS Latency (CL) of 3 clock cycles signifies the delay between the memory controller issuing a read command and the data becoming available from the memory module. This module is classified as Non-ECC (Non-Error-Correcting Code) and Unbuffered. Non-ECC memory is standard for most desktop computers and laptops, where error correction is not a primary requirement. Unbuffered memory, also known as non-registered memory, directly connects the memory module's data pins to the memory controller. This configuration is common in consumer-grade systems but can limit the total amount of memory that can be installed compared to buffered or registered memory found in servers. With a capacity of 1GB, this Hynix module is suitable for upgrading older computer systems or for use in specific embedded applications that require DDR2 memory. It is important to ensure system compatibility, as DDR2 slots are physically different from DDR3 or DDR4 slots, and motherboards are designed to support only specific memory types. The HYMP512U648-E3 AB-A is a reliable component for maintaining or enhancing the performance of legacy systems that still rely on the DDR2 standard.
