Direct Answer: Before spending hundreds on overpriced DDR5 kits—or $3,000+ on a new workstation—there are three ways to combine existing RAM for local AI: Scenario 1 combines GPU VRAM + System RAM inside one PC (slowing to 1–7 tok/s when overflowing to CPU RAM); Scenario 2 mixes physical sticks in empty motherboard slots (blocked across DDR3/DDR4/DDR5 generations, laptop SO-DIMMs, and soldered laptops/Macs); and Scenario 3 uses the RAMDeck Hardware Hub ($199 + Free $29 Zero-Install Node USB) to pool separate Windows PCs, soldered M1–M4 Macs, Linux boxes, and phones over your router in 60 seconds.
One “Unplug & Walk” USB Activates Every Computer in Your Home
Instead of opening PC cases or fighting terminal commands, plug the included Official RAMDeck Node USB into Laptop #1, double-click once to stage the contributor in temporary memory, physically unplug the thumb drive, and walk it over to Laptop #2 and Desktop #3—leaving 0 bytes installed on host drives while creating a 48 GB to 140 GB+ local AI cluster!
