- A 128GB DDR5-6400 kit is listed at $3,399.99 on Newegg, while a 64GB DDR5-6000 Corsair kit is listed at $849.99 at Walmart. [1][2] - Tom’s Hardware’s PCPartPicker-based averages show 32GB DDR5 kits up roughly 473% to 485% year over year, depending on speed. [3] - Samsung and Micron say AI-server demand and limited cleanroom capacity are keeping DRAM supply constrained, while TrendForce says suppliers are reallocating capacity toward HBM and server memory.
[4][5] Retail DDR5 prices have reached extraordinary levels in the United States, but the headline $3,399 figure needs context. Newegg lists multiple 128GB DDR5-6400 kits at about $3,399.99, including G.Skill and V-Color models built from two 64GB modules. Those are high-capacity, high-speed desktop kits and do not represent the typical cost of upgrading a PC. [1]
The broader move is still severe. Walmart lists a Corsair 64GB DDR5-6000 kit at $849.99, while Tom’s Hardware’s comparison of PCPartPicker data puts the August 2026 average for 64GB DDR5-6000 at $1,272, up from $222 a year earlier. Its average for 64GB DDR5-5600 reached $1,118, compared with $191 in August 2025. [2][3]
High-end listings exaggerate the average, not the shortage #
The $3,399 kit is therefore best read as evidence of severe scarcity at the upper end rather than as a market-wide price. Retail listings vary widely by capacity, speed, brand and availability, and some cheaper products are out of stock. Tom’s own tracking table lists a lower $1,891 best U.S. price for one 128GB DDR5-6400 kit, underscoring how quickly channel prices can diverge. [6]
Independent German retail data points in the same direction: 3D Center’s mid-August index put DDR5 prices at 486% of their July 2025 level, or nearly five times higher. [7]
AI demand is tightening conventional DRAM #
The supply pressure begins upstream. Samsung said its memory business expects server DRAM and HBM demand to accelerate in the second half of 2026 and that supply constraints should continue despite softer PC and mobile demand. Micron has separately said HBM’s increasing trade ratio requires more wafers and cleanroom space than conventional DRAM, while new fabs take years to build. [4][5]
That split also helps explain why contract pricing can move before shoppers see a consistent retail price. Hyperscalers and server manufacturers negotiate allocations and long-term agreements, while consumer modules are sold through distributors and retailers whose prices can jump when inventory is scarce. TrendForce said suppliers were reallocating capacity toward HBM and server applications and that consumer DRAM shortages had not eased. [8]
