DEC 20-47281-17 EDO SIMM 60NS 8MX36 DS 72P

Product Description

The DEC 20-47281-17 is a 32 Megabyte (MB) EDO (Extended Data Out) SIMM (Single In-line Memory Module) designed for older computer architectures. EDO RAM was an improvement over standard FPM (Fast Page Mode) RAM, allowing the next memory access cycle to begin before the previous one was completed, thus increasing data throughput. This particular module has an organization of 8Mx36, meaning it consists of eight million bits by thirty-six bits wide, totaling 288 million bits, which equates to 36 Megabytes, but commonly referred to as 32MB due to standard industry naming conventions for SIMMs. With a speed rating of 60 nanoseconds (ns), this SIMM offers a specific access time suitable for the motherboards of its era. The 72-pin configuration is characteristic of EDO SIMMs, distinguishing them from the earlier 30-pin SIMMs and the later 168-pin SDRAM DIMMs. These modules were commonly found in desktop computers and workstations from the mid-1990s, such as those manufactured by Digital Equipment Corporation (DEC) or compatible systems. This memory module is a crucial component for maintaining or upgrading legacy computer systems that rely on EDO SIMM technology. Its specific speed and capacity are important considerations for ensuring compatibility with the motherboard's chipset and BIOS. Finding such components is essential for users who wish to keep vintage computers operational for specific tasks, retro computing, or archival purposes.
