Product Description
This DATARAM 32MB SIMM memory module, identified by the DEC part number 61981-D2, is a legacy component designed to provide essential system memory for the Digital AlphaStation 600 workstation. In the era of its introduction, 32MB was a significant amount of RAM, enabling the workstation to run its operating system and demanding professional applications of the time. The SIMM form factor was standard for memory modules in many computer systems of the 1990s and early 2000s. The module likely utilizes EDO (Extended Data Out) DRAM technology, which offered performance improvements over earlier Fast Page Mode DRAM by allowing the next memory access to begin before the previous one was completely finished. This resulted in faster data retrieval and overall system responsiveness. The typical voltage for SIMMs of this generation is 5V, and speeds often ranged from 60ns to 70ns, depending on the specific implementation and requirements of the AlphaStation 600. As a component specifically listed for the AlphaStation 600, this 32MB SIMM is crucial for users looking to maintain or upgrade these classic workstations. It serves as a direct replacement or expansion module, ensuring the system has adequate memory to function correctly. Given its age and intended use, it is unlikely to feature ECC capabilities, which were more common in higher-end server-grade memory of the period.
