What RAM kit to buy

For Overwatch 2, shop matched dual-channel UDIMM kits at 16GB (2x8GB 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 Overwatch 2. Reserve 32GB builds for heavy Hero Shooter mod stacks or Custom asset packs on Overwatch 2. Live kits below prefer in-stock DDR4/DDR5 modules that clear the 16GB floor for overwatch-2.
