RAM price history, and what it is a history of

Retail RAM history: not enough data to judge. Public semiconductor history: available from 2017-01 through 2026-06. Evidence cutoff: 2026-07-26. BLS PCU334413334413, fetched 25 July 2026 and source registry, reviewed 2026-07-25.

The retained public files do not contain RAM-kit prices. The closest primary context is the BLS index for semiconductor and related device manufacturing, which is much broader than DRAM. No source had been cleared to retain like-for-like retail RAM observations as of the 2026-07-25 review. Source registry, reviewed 2026-07-25.

What the semiconductor index has done

The file contains 114 monthly observations from 2017-01 through 2026-06 with no missing month. The index began at 36.400, reached a retained high of 36.700 in April 2017, reached a retained low of 29.392 in August 2025, and ended at 29.695 in June 2026. The last value was 0.4% below its trailing 12-month mean of 29.829, 0.6% below June 2025, and 18.4% below January 2017. March through June 2026 are provisional. BLS PCU334413334413, fetched 25 July 2026.

This is evidence that the broad semiconductor-manufacturing index sat close to its own recent mean in June 2026. It is not evidence that DDR4 or DDR5 retail prices were flat, and it cannot calculate the price of a particular capacity, speed, timing, or module count. BLS PCU334413334413 series definition, fetched 25 July 2026.

The consumer backdrop has a gap

The not-seasonally-adjusted BLS index for computers, peripherals, and smart home assistants contains 113 observations from 2017-01 through 2026-06. October 2025 is absent from the retained source response and has not been interpolated. The June 2026 value was 35.406, 1.0% above its trailing 12 reported observations, 0.8% below June 2025, and 18.6% below January 2017. BLS CUUR0000SEEE01, fetched 25 July 2026.

The seasonally adjusted and not-seasonally-adjusted consumer series contain identical retained values through June 2026, including the same missing October 2025 observation. We treat them as one signal, not two confirmations. BLS CUUR0000SEEE01 and BLS CUSR0000SEEE01, fetched 25 July 2026.

Why the retail status remains not enough data to judge

A RAM price history must keep the exact manufacturer part number, capacity per module, module count, data rate, timings, XMP or EXPO profile, condition, merchant, and observation time. The public indexes have none of those product fields. Product-identity methodology, published 2026-07-26.

Once a retention-cleared price record begins, a retrospective product state requires at least 14 days, 10 usable price readings, and 60% coverage. Until collection starts, there is no truthful completion date and no earlier retail history will be backfilled. Price-state methodology, published 2026-07-26.

The tested recommendation also remains disabled after the observation window fills. In the 2026-07-26 no-lookahead backtest, waiting was contradicted in 29 of 48 testable three-month signals, or 60.4%, and buying was contradicted in 62 of 118, or 52.5%. Those error rates are why this page describes the recorded indexes but gives no buy-or-wait advice. Verdict methodology, run 2026-07-26.
