If you have not checked memory prices in the past year, today’s listings look like a website bug. Tom’s Hardware compiled PCPartPicker tracking data on August 17: DDR5 average prices are up roughly 500% over 12 months, with some kits at ten times their all-time lows. A 128GB DDR5-6400 kit that once sold for $329 now lists at $3,399. Even DDR4, supposedly obsolete, is swept up in the surge. The era of cheap memory is over for now — and the expansion projects announced this month will not rescue it before 2028.
How Bad Are the Numbers
PCPartPicker’s average-price comparison (August 2025 versus August 2026) is the bluntest evidence. DDR5-4800 2x16GB rose from $90 to $425, up 372%. DDR5-5600 2x16GB went from $116 to $528, up 355%; the 2x32GB version climbed from $191 to $1,118, up 485%. DDR5-6000 2x32GB went from $222 to $1,272, up 473%. Builders squeezed out of DDR5 fled to older platforms, dragging DDR4 up 120% to 180% in the process — a 3200 MT/s 2x16GB kit jumped from $105 to $281. Europe tracks the same pattern: ComputerBase puts RAM prices 345% above September 2025, with HDD and SSD prices up more than 125%. Tom’s Hardware even did the absurdist math: mainstream DRAM chips are now worth more than half as much per kilogram as solid gold.
Who Ate the Memory
The cause is not some mysterious supply-demand wobble; it is AI infrastructure. HBM — the stacked memory soldered beside training and inference accelerators — consumes multiple DRAM layers per device, shrinking the standard memory output each wafer can yield. Against data-center customers placing orders measured in gigawatts and billions of dollars, PC and smartphone makers rank low in the memory vendors’ priority list. The more extreme fact in the reporting: hyperscale buyers have reportedly reserved nearly all global DRAM capacity for 2027 through advance deposits. The windfall shows up in vendor revenue — SK hynix, Samsung, and Micron, plus China’s CXMT, have all doubled or tripled revenue within a year.
Capacity Is Coming, but Not Before 2028
In the same week, StorageReview took stock of the expansion promises from the big three, and the fine print matters more than the totals. Micron committed up to $3 billion to the domestic supply chain, including $500 million in strategic financing for GlobalWafers’ Texas wafer fab, plus a ten-year wafer supply agreement — upstream supply, not DRAM bits. SK hynix announced 54 trillion won (about $38 billion) on August 7 for new DRAM and HBM fabs in Yongin and NAND lines in Cheongju, with cleanrooms not scheduled until late 2028 and mid-2029. Its roughly $4 billion HBM packaging facility in Indiana, backed by a $458 million federal award and a $500 million loan, targets mass production in the second half of 2028. SK Group chairman Chey Tae-won told CNBC the market feels “like a war” and that prices “went up too fast”; CEO Kwak Noh-jung warned that 2027 will be the worst supply year in the industry’s history, with demand exceeding production into 2030. NVIDIA, meanwhile, has already locked in HBM supply under a $500 billion arrangement with SK Group.
What It Means for Builders and Developers
The short-term playbook is clear. Defer non-essential memory upgrades: waiting a quarter now buys a spec downgrade at the same price. Re-price the RAM lines on cloud instance quotes, because providers will pass these costs through. And stop assuming memory costs keep sliding down historical curves in any cost model — for memory-hungry local inference workloads, bandwidth was already the bottleneck, and now capacity itself has doubled in price, which changes the hardware math for home labs and edge boxes alike. The same math applies to anyone quoting hardware builds for clients this quarter. ADATA chairman Simon Chen even thinks the crunch could last another decade. Prices fall again in basically one scenario: a real contraction in AI capital spending. Nobody should wish for a recession just to get cheap RAM back — but the market is now explicitly pricing consumer memory as a casualty of the AI build-out.
