Tom's Hardware Modder saves $130 by building 32GB DDR5 desktop DIMMs from scavenged laptop memory — donor modules soldered to bare PCB flashed with custom firmware even run XMP
DIY DDR5 is no longer just a concept, but a reality, as modder VIK-on has built his first 32GB stick from scavenged parts. The memory chips came from laptop SODIMMs, while a new PCB and cooler were acquired from China. After flashing custom firmware enabling 6400 MT/s XMP, the entire build put together cost $218.
