People often hear that computers contain gold, but not all electronic components contain the same amount.
Some computer parts contain significantly more gold than others, especially older components that were manufactured when gold prices were lower.
This guide explains which computer parts typically contain the most gold.
Ceramic CPUs
Older ceramic processors are often considered one of the richest sources of gold in computer scrap.
These processors sometimes contain:
• gold plated pins
• internal bonding wires
• gold plating under the chip lid
Because of this, vintage ceramic CPUs are often collected by electronic scrap recyclers.
RAM Edge Connectors
RAM sticks contain thin gold plated contacts known as gold fingers.
These connectors help ensure reliable electrical contact with the motherboard.
While the plating is thin, large quantities of RAM modules can contain measurable gold.
Expansion Cards
Older expansion cards such as:
• graphics cards
• network cards
• sound cards
often contain gold plated edge connectors similar to RAM sticks.
Connectors and Cables
Some connectors used in electronics contain small amounts of gold plating for corrosion resistance.
Examples include:
• telecom connectors
• aerospace connectors
• high reliability industrial connectors
Circuit Boards
Circuit boards themselves contain trace amounts of precious metals including:
• gold
• silver
• palladium
However, the concentrations are typically low.
Modern Electronics Contain Less Gold
As electronics manufacturing has advanced, companies have reduced the amount of gold used in devices.
Modern electronics often contain significantly thinner gold plating compared to older equipment.
Final Thoughts
While computers do contain gold, the amount varies greatly depending on the component and its age.
Older electronic components often contain more gold than modern devices, which is why vintage electronics are sometimes sought after by recyclers.
Recommended Gold Refining Supplies
If you're refining scrap gold, jewelry, or electronic components, using the correct chemicals and fresh reagents is critical for consistent results. These supplies are commonly used in the aqua regia gold refining process.
