What RAM kit to buy

For Horizon Forbidden West, shop matched dual-channel UDIMM kits at 32GB (2x16GB dual-channel) before spending on RGB or extreme CL. Populate the primary dual-channel slots (usually A2/B2) and enable XMP/EXPO so DDR5-6000 CL30 actually trains for Horizon Forbidden West. Reserve 64GB builds for heavy Action Adventure mod stacks or Decima asset packs on Horizon Forbidden West. Live kits below prefer in-stock DDR4/DDR5 modules that clear the 32GB floor for horizon-forbidden-west.
