How much does 64GB of DDR5 cost in September 2026?

Roughly $1,099 to $1,272 for a consumer kit. Tracking of Amazon listings on September 11, 2026 put 64GB DDR5 at a median of $17.17 per GB, which is about $1,099 for the kit. Tom's Hardware reported a G.Skill Trident Z5 Neo 64GB kit at $600 earlier in the shortage and warned it would get worse. A 6000 MT/s 2x32GB kit that sold for $222 now tracks at about $1,272. Treat any figure as a snapshot: this market moves weekly.

Is a local AI build still worth it at these RAM prices?

It depends on which resource you are buying. If your plan was a CPU-plus-system-RAM build to run large MoE models from DDR5, the economics got materially worse, because system RAM is the component that repriced hardest. If your plan was a GPU build, VRAM is soldered to the card and the RAM line item is small, so the change is smaller. If your plan was a Mac or a Strix Halo box, the memory is soldered and priced inside the machine, which has so far moved less than the DIMM spot market. The build is still worth it for privacy, for unmetered usage and for offline work. It is a weaker pure cost argument than it was in 2025.

Should I buy less RAM and more VRAM now?

For most local LLM work, yes. System RAM only helps when you are offloading model layers to the CPU, which is slow. VRAM and unified memory are where the tokens per second come from. At today's prices, spending an extra $500 on DDR5 to enable slow CPU offload is a worse purchase than spending it toward a card with more VRAM. The exception is large MoE models such as gpt-oss 120B, where CPU offload of expert weights is a legitimate strategy and system RAM capacity genuinely decides what runs.

Will RAM prices come down in 2027?

No published forecast we have read calls a bottom before 2027, and several extend the tightness through it. Samsung and SK Hynix are reported to be filling only about 70% of orders, with smaller OEMs and channel distributors told to expect 35 to 40% fulfilment. IDC has warned average PC prices could rise as much as 8% in 2026 on the memory crunch. Planning a purchase around a price drop is a bet against the supply data.

RAM Prices for Local AI, September 2026: 64GB DDR5 Now Costs More Than a PS5

In October 2025 a 64GB DDR5 kit cost about $222. In September 2026 the same class of kit tracks at roughly $1,099 to $1,272. That is a 473-485% rise, and it lands directly on the one component a local AI build needs most of. This page is the current price picture by capacity, what it does to a build budget, and the three paths that still make sense at these numbers.

Bottom Line

A 64GB DDR5 kit costs roughly $1,099-$1,272 in September 2026, against about $222 before the shortage. That is a 473-485% rise. [source: capitalandcompute DDR5 tracker, 2026-09-11; Wccftech memory crisis roundup]
The cause is the AI data centre buildout, not consumer demand. Server DRAM shares fab capacity with consumer DDR5.
DDR5 contract prices rose 90-95% in a single quarter (Q1 2026), the largest on record. [source: TrendForce via search summary]
Supply is rationed. Samsung and SK Hynix are reported filling about 70% of orders; channel distributors are told to expect 35-40%.
The advice this changes: stop buying system RAM to enable CPU offload. Put the money into VRAM or unified memory instead.
The advice it does not change: if you need the memory inside 12 months, buy it now. Nothing in the supply data points down.

Current Prices by Capacity

These are snapshots. This market repriced twice while we were writing about it, so check the day’s listing before you buy.

Capacity	Rough street price, Sept 2026	Pre-shortage reference
16GB DDR5 kit	see listing	—
32GB DDR5 kit (2x16)	~$350+	$100-200 (Oct 2025)
64GB DDR5 kit (2x32)	~$1,099-1,272	~$222
DDR4 per chip	$42.50 record	—

The per-gigabyte figure is the cleaner way to read it. Amazon listing tracking on September 11, 2026 put 64GB DDR5 at a median $17.17/GB, with another tracker reporting $22.41/GB across its product set. Before the shortage, consumer DDR5 sat in low single digits per gigabyte.

Our own earlier page is now out of date on this. Our August 11 buy-now-or-wait analysis quoted $680-880 for a 64GB kit. One month later the same kit class tracks $1,099-1,272. We have corrected that page. We are flagging the change here because the direction of the error matters: every stale RAM price on the internet is too low, including ones we published.

What This Does to a Local AI Build

Take the three common build shapes and apply the new memory line.

Build shape	Memory type	Exposure to the shortage
GPU build (3090 / 4090 / 5090)	VRAM soldered to the card + modest system RAM	Low-medium. Card prices carry memory cost, but you are not buying 64GB of DIMMs.
CPU + system RAM MoE build	DDR5 DIMMs, 96-256GB	Severe. This is the build the shortage broke.
Mac or Strix Halo unified memory	Soldered LPDDR5X, priced into the machine	Low so far. Soldered memory did not track the DIMM spot market.

The middle row is the one to think hardest about. Running a large MoE from system RAM was a real strategy in 2025 — buy 128GB of cheap DDR5, offload the expert weights, accept slow tokens. See running an LLM without a GPU and can I run a local LLM with 128GB RAM and no GPU for how that path works.

At $17/GB, 128GB of DDR5 is roughly a $2,200 line item on its own. That is the price of a used A6000 with 48GB of actual VRAM. The cheap-RAM strategy was cheap. It is not any more.

The Three Paths That Still Work

1. Buy the memory you need, today

If a build is happening in the next 12 months, the forecast risk is one-sided. Nothing published calls a bottom before 2027. Waiting is a bet against TrendForce, against the fulfilment figures, and against IDC’s 8% PC-price warning.

DDR5 kits, current listings

Prices on these move weekly and stock-outs are common. Check the listing price against the per-GB figures above before you commit — at these levels a bad day costs real money.

2. Move the budget from system RAM to VRAM

This is the change most readers should make. System RAM buys you slow CPU offload. VRAM buys you tokens per second. When DDR5 was $3/GB the offload path was a bargain. At $17/GB it competes directly with real graphics memory, and it loses.

Concretely: if your plan was 128GB of DDR5 plus a 12GB card, invert it. A 24GB or 32GB card plus 32GB of system RAM will run more models faster, for similar money. See 32GB vs 64GB RAM for local LLM for where the real capacity thresholds sit, and the cheapest 32GB VRAM GPU in 2026 for the other side of the trade.

3. Buy soldered memory instead of DIMMs

Unified-memory machines price their memory inside the machine, on a supply chain that has so far not tracked the DIMM spot market. A Strix Halo mini-PC or a Mac with 128GB of unified memory is now competing against a DIMM stack that tripled in price.

This is the hedge our August page named, and one month of further DIMM inflation has only strengthened it. See which Strix Halo mini PC to buy and Mac mini vs GPU for local LLM.

One caution. Soldered memory cannot be upgraded. At the moment that is an advantage, because you are locking in today’s price on a machine. If DRAM normalises in 2027, a DIMM machine can be upgraded cheaply and a soldered one cannot. You are trading future flexibility for present certainty.

What We Are Not Claiming

We have not measured these prices ourselves. They come from published trackers and reporting read on 2026-09-12, and they are cited inline.
We do not know when the shortage ends. Nobody publishing does. The forecasts agree on direction, not on a date.
Retail pricing is not contract pricing. Contract figures move first; your checkout total follows with a lag and with retailer margin on top.

FAQ

How much does 64GB of DDR5 cost right now?

Roughly $1,099 to $1,272 for a consumer kit as of September 2026. Amazon listing tracking on September 11, 2026 put 64GB DDR5 at a median of $17.17 per GB, which is about $1,099 for the kit. A 6000 MT/s 2x32GB kit that sold for $222 before the shortage now tracks around $1,272. This market moves weekly, so check the listing rather than trusting any published figure, including this one.

Why did RAM prices rise so much in 2026?

AI data centre construction absorbed the DRAM supply. NVIDIA H100 and H200 accelerators carry 80 to 141GB of HBM3 or HBM3e each, and volume production consumed a large share of Samsung, SK Hynix and Micron capacity. Server DRAM shares fabrication capacity with consumer DDR5, so consumer prices followed. TrendForce reported DDR5 contract prices up 90 to 95% in Q1 2026, the largest single-quarter rise on record, and DRAM is up about 171.8% year over year.

Should I buy RAM now or wait for prices to fall?

Buy now if you need it inside 12 months. No published forecast we have read calls a bottom before 2027. Samsung and SK Hynix are reported filling about 70% of orders, and channel distributors are told to expect 35 to 40% fulfilment. IDC has warned PC prices could rise up to 8% in 2026 on the memory crunch. If you already have enough RAM, do nothing — this is a reason not to delay a purchase you needed, not a reason to upgrade early.

Does the RAM shortage change which local AI build I should make?

Yes, in one specific way. The CPU-plus-large-system-RAM build, where you offload model layers to DDR5 and accept slow tokens, was attractive because DDR5 was cheap. At roughly $17 per GB it is not. Move that budget to VRAM or to a soldered unified-memory machine. GPU builds and Mac builds are far less exposed, because their memory is either on the card or priced inside the machine.

Are Mac and Strix Halo prices affected too?

Less so, so far. Soldered LPDDR5X is bought inside the machine's own supply chain and has not tracked the DIMM spot market the way consumer kits have. That makes unified-memory machines relatively better value than they were a year ago, purely because the alternative got more expensive. The trade-off is that soldered memory cannot be upgraded later, so you are locking in today's capacity along with today's price.
