Additional Details:

This Hynix memory module is likely DDR3 SDRAM, although DDR2 or DDR4 are possible depending on manufacturing date. The 256Mx8 configuration describes the arrangement of memory cells within the module. A CAS Latency of 18C, refers to the delay between the memory controller requesting data and its availability. Always consult the datasheet prior to installation to check the voltage requirements, frequency, and precise timing parameters. Proper handling to avoid ESD damage is crucial during installation. The presence of the trailing '3' in the part number likely denotes a specific revision or sub-specification of the memory module, potentially related to manufacturing process or internal components.
