Board Guy Category: RAM – Vintage (Pre-DDR)
Notes: Early memory modules manufactured before the introduction of DDR (Double Data Rate) technology. Includes 30-pin SIMMs, 72-pin SIMMs, FPM, and EDO memory. Often recognised by gold-plated edge connectors, older chip packaging, and lower component density compared to modern RAM.
Overview
Vintage RAM modules are among the most sought-after memory types in electronics recycling due to their age, construction, and precious metal content. Manufactured throughout the 1980s and 1990s, these modules were commonly used in early desktop computers, workstations, industrial equipment, telecommunications hardware, and servers.
Unlike many modern electronic components, older memory modules frequently contain heavier gold plating on their edge connectors and were produced during a period when manufacturers used more precious metals in electronic assemblies. As a result, vintage RAM often attracts significantly higher recycling values than modern memory.
Most vintage RAM is found in the form of SIMM (Single Inline Memory Module) boards, particularly 30-pin and 72-pin varieties. These modules are easily recognised by their long, narrow shape and distinctive gold fingers along one edge.
Identifying Vintage (Pre-DDR) RAM
Identifying Vintage (Pre-DDR) RAM
Common characteristics include:
• 30-pin or 72-pin SIMM form factors
• Gold-plated edge connectors
• Older black rectangular memory chips arranged in rows
• Single-sided or double-sided chip populations
• Labels referencing FPM, EDO, parity, or capacities measured in MB rather than GB
• Found in vintage desktop computers, servers, industrial controllers, and telecommunications equipment
Common examples include:
• 30-pin SIMM memory
• 72-pin SIMM memory
• FPM (Fast Page Mode) RAM
• EDO (Extended Data Out) RAM
• Early server memory modules
• Industrial and telecommunications memory boards
Vintage RAM should not be confused with modern DDR, DDR2, DDR3, DDR4, or DDR5 memory modules, which are graded separately due to their different composition and recycling value.
Preparation for Recycling
Vintage RAM is generally accepted complete and intact.
For best results:
• Leave all chips attached to the module
• Do not break or cut the memory sticks
• Remove any plastic carriers, brackets, or non-electronic packaging
• Keep vintage RAM separate from modern RAM where possible
Because pre-DDR memory is increasingly scarce, correctly identifying and separating these modules can significantly improve the value of a mixed electronics collection.
