Why Is RAM So Expensive Right Now?

The short answer

RAM is expensive because the companies that make memory chips have found a far better paying customer than you: AI and cloud data centers. Every wafer that goes to a server is a wafer that does not become a desktop or laptop kit. On top of that, DDR4 is being retired and new factories take years to come online, so supply cannot catch up quickly.

This page is one part of our wider RAMageddon explainer, which follows the whole shortage. Here we stick to one question: what exactly pushes the price of a kit up, and which of those causes are likely to last.

AI servers outbid your PC

Most of the world's DRAM comes from three makers: Samsung, SK hynix and Micron. In the first quarter of 2026 they held 38.5%, 28.8% and 22.4% of DRAM revenue, according to TrendForce. When three companies control that much of the supply, their choices about what to build set the price for everyone else.

Those choices favor AI. High bandwidth memory (HBM), the stacked memory on AI accelerators, needs about three times as much wafer space as DDR5, Micron said on its December 2025 earnings call, as reported by Tom's Hardware. On the same call Micron said it could meet only half to two-thirds of demand from its key customers. Two weeks earlier it had announced its exit from the Crucial consumer business to support those larger customers. Micron still makes chips that end up in other brands' modules, but its own retail brand is gone, and Crucial warranties stay in place.

Demand is also spreading beyond HBM. TrendForce reported in June 2026 that servers for AI inference and agentic AI use standard DDR5 server modules, which compete directly with the chips behind consumer DDR5. Big cloud providers also lock in supply with multi year agreements, TrendForce reports, so a growing share of output is spoken for before it reaches the open market.

DDR4 is not the cheap way out

Usually the old generation gets cheaper when a new one takes over. This time all three big makers announced in 2025 that they would wind down DDR4 to free up lines for DDR5, LPDDR5 and HBM. Server buyers kept ordering DDR4 anyway, which squeezed what was left for PCs.

The effect showed up fast. In July 2025, 8GB DDR4 PC modules became more expensive than 8GB DDR5 modules, a rare inversion TrendForce flagged in August 2025. On the spot market, TrendForce put the benchmark DDR4 chip at US$5.947 in late September 2025 and at US$23.746 by December 30, 2025, roughly four times higher in three months.

So if your PC takes DDR4, check current DDR4 prices before you assume the older kit is the budget choice.

New factories need years

Making more DRAM is slow. TrendForce wrote in June 2026 that suppliers add output mainly by moving to finer processes, because new cleanrooms take time to build. Micron's first new Idaho fab was expected to start producing in mid 2027, with its New York fab around 2030, according to its December 2025 outlook.

And most of the new capacity at the big three is aimed at HBM and server memory first. That is our reading of the plans, not a promise from any maker, but it means a new fab does not automatically lead to cheaper desktop DDR5.

On its September 30, 2026 earnings call, Micron CEO Sanjay Mehrotra said demand would exceed supply in 2027 and 2028, with tightness greater than in 2026, Tom's Hardware reported. TrendForce expects conventional DRAM contract prices to climb another 10% to 15% quarter on quarter in the fourth quarter of 2026, and says PC makers are buying ahead because they expect tight supply in 2027.

The makers are earning record margins

High prices are not a sign that memory makers are struggling. Micron reported revenue of $54.23 billion for its fiscal fourth quarter of 2026, up from $11.32 billion a year earlier, with a GAAP gross margin of 86.8%. With margins like that on server memory, there is little reason to move capacity back to consumer kits soon.

Not everyone agrees on the outlook. Acer CEO Jason Chen told DigiTimes, as reported by TechSpot, that he expects PC prices to peak in the first half of 2027 and then ease, partly thanks to cheaper Chinese supply. Micron and SK hynix point the other way.

Are tariffs to blame?

Not as far as the evidence goes. None of the primary sources we use name US tariffs as a main driver of the surge; they all point to AI demand and capacity allocation. A Section 232 proclamation from January 14, 2026 does put a 25% tariff on certain semiconductor imports, according to trade compliance firm AEB, but how it applies to retail RAM kits has not been verified, so we do not put a tariff figure on a kit.

What a kit costs in the US this week

Retail prices follow contract and spot prices with a lag of weeks to months. TechPowerUp, using PCPartPicker data, reported that US DDR5 kit prices in August 2026 were 372% to 485% higher than a year earlier, depending on the kit. A 64GB DDR5 6000 kit went from $222 to $1,272 over that year.

The table shows our own figures from Adorama, Amazon.com, B&H Photo, Best Buy, Corsair.com, Newegg and Walmart, from the latest check on November 2, 2026. Prices are excluding sales tax.

Change in the median DDR5 desktop price per GB over 4 weeks: not measured yet. Over 12 weeks: not measured yet. Change since October 13, 2026: not measured yet. Our US tracking is young, so these figures cover the period since we started, not the whole surge. The RAM price chart shows how the weeks add up, and the 32GB RAM price page lists every kit in the most popular size.

If you need memory now, buy the capacity you need and compare the price per GB across all RAM prices. If it is an upgrade that can wait, waiting costs little, but none of the forecasts above point to a quick drop.

What we do not know yet

• How much of the new fab capacity in 2027 and 2028 will go to consumer DDR5 rather than HBM and server memory.
• Whether cheaper supply from smaller makers such as China's CXMT reaches US shops in volume.
• Whether demand for AI inference servers keeps growing at the current pace.
• How US tariffs on semiconductors apply to memory modules in practice, and whether the open ITC patent case over DRAM devices ends in an import ban.
