Server RAM prices: what a DDR5 RDIMM costs in 2026

Server RAM prices: frequently asked questions

How much does server RAM cost per GB in 2026?

About $29.56 to $39.06 per gigabyte for a new in-stock DDR5 ECC RDIMM, with a tracked median of $35.70 as of August 14, 2026. These are single-retailer street prices for new modules, not the contract prices hyperscalers negotiate, and not the much cheaper used-server-pull market. A consumer DDR5 kit averages $16.20 per GB over the same week, so registered ECC memory carries roughly a 2.2x premium per gigabyte.

Why is server memory more expensive per GB than desktop memory?

Three reasons compound. Registered ECC modules carry extra silicon (a register or buffer plus the ECC dies), so there is more part per gigabyte. They ship in far higher capacities per module, and capacity is exactly what repriced in this shortage. And they sit in the demand path of the AI build-out, which is the buyer with the least price sensitivity in the market. The consumer channel gets the leftovers of a shortage; the server channel is the shortage.

Are cloud providers paying these price increases?

Not all of them, and that is the most underreported mechanic in this market. Several U.S.-based CSPs have entered into multi-year long-term agreements which, in TrendForce's words, restrict suppliers from raising prices for these clients. From 3Q26 the primary source of server DRAM price increases shifts toward customers without an LTA, and toward incremental supply sold outside an LTA to existing LTA customers. In practice a large US cloud provider with an agreement signed before the squeeze holds its price while a smaller buyer, an enterprise refresh or a regional host pays the full 13 to 18% quarterly increase. Reported "server memory prices" are therefore an average of two very different experiences.

Why are buyers switching to smaller RDIMM modules?

Because the largest module is now the worst value per gigabyte. CSPs and OEMs have gradually adjusted their RDIMM configurations, with some systems shifting from 96GB and 128GB modules to 32GB and 64GB modules. The tracked prices show what that avoids: 128GB runs $39.06 per GB against $32.25 for 64GB, so hitting 128GB with two 64GB modules costs about $4,128 instead of $5,000, roughly 17% less. The trade-off is DIMM slots and future headroom, which buyers are now willing to spend. Note that the 128GB and 256GB figures rest on a single tracked listing each, so treat them as thin-liquidity readings rather than a settled market price.

When will server RAM prices stop rising?

No forecaster on record has called a peak in the contract market. What has changed is the pace: TrendForce now expects the 3Q26 increase to moderate to 13 to 18% for conventional DRAM, partly because with contract prices already at record highs and consumer demand slowing, TrendForce reports that price tolerance among consumer customers has reached its limit, which is why it expects the 3Q26 increase to moderate to 13-18% even as AI server demand holds. Note the asymmetry in that sentence: the moderation comes from consumer buyers refusing, not from supply arriving. AI server demand is still the bid, and buyers are stockpiling against an even tighter 2027.
