How Much Does 256GB of DDR5 RAM Cost?
As of late October 2026, 256GB of DDR5 server RAM costs roughly $11,600 to $13,400 as a kit, and a single 256GB module has been listed at about $7,500. Consumer DDR5 would cost less per gigabyte, but 256GB on a consumer platform needs 64GB modules and a motherboard that supports them. Prices change daily with the DRAM shortage.

What Affects the Price
- Module type: ECC RDIMM costs more than non-ECC consumer RAM.
- Module size: larger modules often cost more per gigabyte. A single 256GB module can cost less per GB than several smaller ones.
- Speed: DDR5-6400 costs more than DDR5-4800.
- Market conditions: AI demand for memory has pushed DRAM prices sharply higher through 2026.
