Steam Machine energy boosts with a second memory stick, delivering up to 20% more in some tasks
Valve ships Steam Machines with a single 16GB DDR5-5600 module, keeping the system in single-channel mode; GamersNexus benchmarks show adding a second identical stick to enable dual-channel can yield up to ~20% gains, especially in CPU-heavy tasks and certain games (e.g., Baldur’s Gate 3, Resident Evil 4, Outer Worlds 2), while some titles see little difference. Valve previously suggested negligible impact, but all units ship with one module and only gain the bandwidth benefits once a second stick is added.
