Ddr2 667 4g

The market for DDR2 667 4GB memory is currently experiencing a rare and dramatic resurgence. Driven by a global AI memory crisis, this legacy standard has transitioned from an obsolete component to a high-demand commodity with prices surging by over 55% in early 2026. ThenextwebTheregister

Core Market Trends (2026)

* The "Trickle-Down" Shortage: Massive reallocation of wafer capacity to High-Bandwidth Memory (HBM) for AI has caused a shortage in DDR4 and DDR5. Consequently, manufacturers are "downgrading" hardware designs to DDR3 and eventually DDR2 to maintain production of industrial and networking equipment. ThenextwebVersalogic

* Price Explosion: Contract prices for DDR2 jumped 55-60% in Q2 2026, with further increases of 35-40% projected for Q3. ThenextwebTheregister

* Supply Scarcity: Major fabs like Winbond are exiting DDR2 production. While smaller players like ESMT remain, they cannot fully offset the lost capacity, making 4GB modules particularly difficult to source in bulk. ThenextwebTechpowerup

Product Analysis & Sourcing Insights

* Pricing: B2B prices for 4GB DDR2 667MHz modules currently range from $18 to $35 per unit, significantly higher than historical norms. AlibabaAlibaba

* Availability: While consumer stock is limited, specialized B2B suppliers in Shenzhen still maintain inventory for industrial use cases. AlibabaAlibaba

* Technical Note: High-density 4GB single-stick DDR2 modules are rare; many "4GB kits" consist of 2 x 2GB modules. True 4GB single modules often require specific chipset compatibility (e.g., AMD-only or high-density Intel boards). AlibabaNewegg
