Modder boosts original PlayStation RAM to 16MB with PC chips
Retro hardware enthusiasts keep proving that vintage gaming gear still holds unlocked secrets decades after release.
A modder known as TunerTom, working alongside the PSX.dev community on Discord, successfully upgraded the original PlayStation console memory from 2MB to 16MB. The process required desoldering the four factory 512KB EDO RAM chips and replacing them with eight 2MB chips salvaged from obsolete PC memory modules.
Because the original motherboard lacked physical room for eight chips, four of the new RAM units were piggybacked directly on top of the others with custom wiring, trace cuts, and a 22-ohm resistor. This mod unlocks hidden hardware capability that Sony built into the console's processor for arcade machines but omitted from retail units.
While standard commercial games do not see performance gains and titles like Final Fantasy IX fail to boot entirely, the massive memory expansion opens huge possibilities for homebrew developers and ports. A custom port of Super Mario 64 from the Nintendo 64 was already demonstrated running on the modified console by Tito Perez on his channel Macho Nacho Productions.
TunerTom is currently preparing a follow-up modification aimed at doubling the console's video RAM from 1MB to 2MB.
The endless drive to push vintage hardware beyond its physical limits proves that passion often trumps practical utility, even if breaking game compatibility is the price for quirky technical flexing.
