HP D5363-63001 64MB Mx64 PC100 DIMM 168-pin Memory Module

HP D5363-63001 64MB Mx64 PC100 DIMM 168-pin Memory Module

This is a 64MB SDRAM memory module in the standard 168-pin DIMM form factor, compatible with computers from the late 1990s that supported PC100 synchronous DRAM. The module was pulled from a Compaq Deskpro 4000 desktop system, a popular business-class computer of that era. It carries the HP part number D5363-63001 and operates at 100MHz bus speed, the standard for PC100 memory.

Applications

PC100 SDRAM DIMMs like this one were the standard memory upgrade for desktop computers from the mid-to-late 1990s through early 2000s. The Compaq Deskpro 4000, from which this module was removed, was a common business-class system used in offices and schools throughout the late 1990s. This module is suitable for upgrading or repairing compatible legacy systems including Compaq Deskpro and HP Pavilion machines, as well as many other systems that used the 168-pin DIMM slot and supported PC100 memory. While these systems are largely obsolete for everyday use, they remain in service for specialized applications, retrocomputing hobbyists, and environments where legacy software compatibility is essential. Memory modules of this type are also sought after by collectors and system restorers working on period-appropriate repairs.
