Steam Machine RAM Upgrade Costs $225, Eases 1x16GB Bottleneck

Q: Is Valve's new Steam Machine already obsolete due to the global memory crisis?

No. Valve’s new Steam Machine is not already obsolete because of the memory crisis, but the crisis has made it a worse value and a more compromised product than it should be. The clearest impact is on cost and configuration. Valve shipped the system with a single 16GB DDR5-5600 SODIMM because it could not reliably source two 8GB sticks during a severe global DRAM shortage. That shortage is being driven by AI and server demand, with memory makers prioritizing higher-margin HBM and server DDR5 over consumer RAM. As a result, consumer DDR5 prices have surged and are expected to stay elevated well into 2027. That does hurt performance. A 1x16GB setup limits memory bandwidth versus a normal dual-channel arrangement, and testing shows real losses in CPU-bound workloads and some games. Baldur’s Gate 3, for example, benefits from dual-channel memory, while Cyberpunk and Resident Evil 9 show smaller gains. Valve is right that many titles will still run acceptably, but the machine is objectively leaving performance on the table. The bigger problem is ownership. Upgrading is expensive, matching RAM is difficult, and the compact chassis makes access far more involved than on a standard PC. That turns a fixable design compromise into a frustrating one. So the Steam Machine is not obsolete in the strict technical sense. It remains a capable compact SteamOS PC. But the memory crisis has made it overpriced, harder to upgrade, and less competitive, which weakens its long-term appeal.

$225 bought a matching 16GB DDR5-5600 SODIMM that let the author convert Valve’s Steam Machine from single-channel 1x16GB memory to dual-channel RAM without instability.
Valve shipped all current units with one 16GB stick because of supply constraints, a setup that mostly leaves GPU-bound games alone but can drag CPU-heavy workloads such as Baldur’s Gate 3 and file compression.
The upgrade is awkward as well as expensive: reaching the RAM requires removing the fan, power supply, four ribbon cables and antenna connections, though the storage drive is easier to access.
Testing showed steadier performance in Baldur’s Gate 3’s Lower City and gains in some other titles, broadly matching Gamers Nexus findings that dual-channel memory can deliver meaningful uplifts in select cases.
Valve told Gamers Nexus future builds could change, but for now every shipping machine remains 1x16GB, leaving buyers to weigh a tricky teardown and high RAM prices against limited real-world gains.
