This document is a Technology Procurement Memo filed by the Department of Random Domain Management.

The originating agency, RamSeeker, has submitted a guide titled "Check RAM Compatibility with Motherboard: Complete Compatibility Guide."

Our office has reviewed the materials for arbitrage and futures positioning implications.

The guide addresses three core market factors: specification matching, Qualified Vendor List (QVL) cross-referencing, and top-tier DDR4 and DDR5 DIMM selections for the 2026 contract cycle.

Specification matching refers to the alignment of latency timings, voltage curves, and channel density against motherboard trace layouts.

QVL lists represent the only officially hedged inventory positions; any stick not on the QVL carries unhedged physical settlement risk.

Top RAM choices for DDR4 and DDR5 in 2026 have been identified by the agency as high-liquidity SKUs with stable bid-ask spreads.

Market participants should note that DDR5 currently trades at a premium to DDR4 due to new platform bond issuance and channel capacity constraints.

Arbitrage opportunities exist when motherboard QVLs exclude otherwise fungible sticks, creating artificial scarcity spreads.

The guide does not offer pricing forecasts but does provide the underlying physical delivery parameters needed to calculate basis risk.

This memo serves to log the publication for our internal reference book and to flag any subsequent price divergence from expected QVL-implied parity.

Signed, DDR, Senior Memory Arbitrage Clerk, Department of Random Domain Management.
