Description
DDR5 represents the newest generation of enterprise and consumer memory. While functional DDR5 5600MT/s modules hold significant resale value in IT asset recovery, end-of-life, mechanically damaged, or locked modules offer excellent base and precious metal recovery yields for bulk recyclers.
Material Yield & Precious Metal Profile
Like previous generations, DDR5 memory is classified as high-grade e-waste due to the heavy concentration of precious metals required for data transmission.
-
Gold Recovery: The primary scrap value comes from the edge connectors (gold fingers). DDR5 utilizes a 288-pin (UDIMM/RDIMM) or 262-pin (SO-DIMM) layout. While pin counts are higher than older generations, modern manufacturing uses thinner gold plating. Average consumer DDR5 modules yield approximately 0.03g of gold per unit, heavily concentrated on the connectors.
-
Palladium & Silver: Trace amounts of palladium and silver are heavily concentrated in the memory ICs (Integrated Circuits) and surface-mounted capacitors.
-
Copper & Tin: DDR5 contains high-density, multi-layer printed circuit boards (PCBs) that yield excellent copper recovery once the precious metals are stripped.
The DDR5 Architectural Difference (Scrap Perspective)
When assessing DDR5 against DDR4 or DDR3 scrap, the physical architecture of the board has changed, which slightly alters the material yield:
| Feature | DDR4 RAM | DDR5 RAM | Scrap Impact |
| Power Management | On Motherboard | On RAM (PMIC) | Higher yield. DDR5 includes an onboard Power Management IC and Voltage Regulating Module, adding micro-components, trace palladium, and copper to the board. |
| Density/Chips | Lower density | Higher density | Higher yield. DDR5 features dual 32-bit channels per stick and denser IC stacking, increasing the volume of black silicon chips to process. |
| Pin Count | 288-pin / 260-pin | 288-pin / 262-pin | Neutral. Similar pin count, though gold plating thickness is optimized for cost savings compared to vintage RAM. |
