Check → DDR5 RAM prices, ranked by $/GB.
Memory makers pivoted to HBM for AI datacenters, so DDR5 is in a deep shortage — up 3-4× since 2025. We track desktop kits by dollars per GB so you can spot value and buy on the dips. Live Amazon prices, refreshed daily.
DDR5 kits by $/GB
Lower $/GB is better. DDR5-6000 CL30 is the gaming/AM5 sweet spot. Tap Check → for live listings.

Prices are the lowest current new kit per profile. DDR5 is shortage-inflated across the board right now — the tracker turns green if/when $/GB falls back toward pre-2025 levels.
How much RAM — gaming vs AI
| Capacity | Good for |
|---|---|
| 32 GB | Gaming floor; AI only if the model fits entirely in GPU VRAM |
| 64 GB | The AI sweet spot — enables CPU offload of larger models (e.g. 70B Q4 with a 16GB GPU) |
| 96 GB | Headroom for big context windows and heavier offload |
| 128 GB | Future-proof; large-model CPU offload and big local datasets |
For AI CPU-offload, both capacity (does it fit?) and bandwidth (how fast) matter — which is why DDR5-6000 beats slower kits for token generation.
Why $/GB?
Capacity is what lets you run bigger games and offload bigger models, so the honest value metric for memory is dollars per GB. We show the lowest current new kit per profile and link straight to Amazon; prices older than 24 hours are hidden rather than shown as current.

DDR5 RAM FAQ
How much RAM do I need for local AI?
32GB is the floor, 64GB is the sweet spot, and 128GB is future-proof. Once you offload part of a large model from the GPU to system RAM, more (and faster) RAM directly raises tokens/sec — community benchmarks show 64GB lets a 16GB GPU run a 70B model at Q4 with partial CPU offload at usable speeds — something 32GB cannot do comfortably (it is marginal and pages to disk).
What DDR5 speed should I buy?
DDR5-6000 with CL30 timings is the mainstream sweet spot, especially on AMD AM5, where the memory controller stays in sync 1:1 with the memory (UCLK:MCLK) up to 6000 MT/s; push past 6000 and it drops to 1:2, which hurts latency. For AI CPU-offload, memory bandwidth raises token-generation speed, so faster DDR5 helps.
Why is DDR5 so expensive in 2026?
Memory makers shifted capacity toward HBM for AI datacenters, creating a severe DRAM shortage. DDR5 prices rose roughly 3-4× from 2025 lows, and analysts do not expect meaningful relief before late 2027 — so $/GB is the number to watch, and buying on any dip matters.
Does RAM speed affect gaming?
Yes, modestly — faster, tighter DDR5 (6000 CL30) improves 1% lows and CPU-bound frame rates on AM5 and recent Intel platforms, though the gains are smaller than capacity or GPU upgrades.
