Description
DDR4 memory modules (including 3200MHz variants) are a highly sought-after commodity in the e-waste and precious metal recovery industry. As the standard memory generation for recent enterprise servers, gaming PCs, and modern laptops, DDR4 scrap is becoming increasingly abundant as IT asset disposition (ITAD) cycles refresh older hardware.
For precious metal refineries and scrap aggregators, DDR4 represents a steady, high-grade source of gold (Au), palladium (Pd), silver (Ag), and copper (Cu).
Precious Metal Yield & Material Composition
While newer generation RAM like DDR4 generally features slightly thinner gold plating on the edge connectors compared to vintage memory (like SDRAM or DDR1), it remains a premium, high-yielding category due to the density of the surface-mounted components.
-
Gold (Au): Primarily found on the 288-pin (desktop) or 260-pin (laptop) edge connectors (“gold fingers”). Gold is also recovered from the microscopic bonding wires inside the black BGA (Ball Grid Array) memory chips.
-
Palladium (Pd) & Silver (Ag): Extracted from the Monolithic Ceramic Capacitors (MLCCs) surface-mounted across the PCB.
-
Copper (Cu): High-grade copper is recovered from the internal conductive layers and traces of the multi-layer printed circuit board (PCB).
-
Aluminum (Al) / Steel: Found exclusively on modules that feature aftermarket or OEM thermal heat spreaders (heatsinks).
Scrap Sorting & Purchasing Categories
To maximize payout and processing efficiency, DDR4 scrap should be graded into the following standardized categories:
| Grade Category | Description | Processing Note |
| Clean Bare RAM (Gold Finger) | Standard green, blue, or black PCB modules with no heat spreaders attached. Both desktop and laptop sizes apply. | Highest Value. Requires no mechanical prep before shredding/chemical stripping. |
| RAM with Heat Spreaders | Modules encased in aluminum or steel cooling shields (common in gaming and high-performance ITAD scrap). | Lower Price per lb/kg. Must be mechanically separated or priced to account for non-precious base metal weight. |
| Server/ECC RAM (RDIMM) | Server-grade DDR4 memory. Typically contains additional register chips and more dense MLCC configurations. | Often purchased at a premium over standard consumer RAM due to higher chip density and precious metal content. |
| Trimmed/Depopulated RAM | PCBs where the gold fingers have been cut off or the BGA memory chips have been removed. | Downgraded. Purchased as standard mid-grade or low-grade telecom board scrap. |
