Direct Answer: Yes, you can combine the RAM of two, three, or five computers (and even iPhones or Android phones) over your local Wi-Fi or Ethernet network to run massive 30B, 70B, and 120B AI models that would crash on any single computer alone. Using the plug-and-play RAMDeck Hardware Hub ($159 Indiegogo Special + Free $29 Node USB), three 16 GB computers combine into a 48 GB memory pool (~42 GB usable) in under 60 seconds with zero command-line setup.
Comparing Your Options: RAMDeck Plug-and-Play Hub vs. Developer CLI Tools
- RAMDeck Hardware Hub ($159 + Free $29 Zero-Install Node USB): A turnkey appliance that plugs into your router and automatically discovers Windows, macOS, Linux, iOS (Apple App Store), and Android devices. It prioritizes fast GPU/Metal memory first, heals within 3 seconds if a laptop sleeps, and includes the Zero-Install Node USB so one thumb drive can activate every computer in your house (watch the 5-minute unboxing walkthrough).
- Developer Command-Line Tools (Exo / Manual Open-Source RPC): Free open-source frameworks built for programmers comfortable configuring terminal windows, firewall rules, and manual memory splits across each machine.
What Speeds Do You Get When Combining RAM?
- Fast GPU & Apple Silicon Clusters: 38–39 tokens/sec on Qwen3-Coder 30B (RTX 3060 Mini PC + Mac mini M4) and 28 tokens/sec on Qwen 30B across an M3 MacBook + iPhone 16 + iPhone XS.
- Old-PC CPU Rescue Clusters: 11–19 tokens/sec on Qwen3.5 13B Dense, 1.92 tokens/sec on Qwen3.8 27B Dense (anchored on a 2019 CPU-only Acer laptop), and 3.1 tokens/sec on a 60 GB+ 120B model across 5 PCs (Mac + Windows + Ubuntu Linux).
