The author attempted to turn a Raspberry Pi 5 into the World’s Fastest Pi 5, trying various methods including using liquid nitrogen for extreme cooling and adding the ElmorLabs AMPLE-X1 power card to address voltage issues. Despite software indicating 4 GHz, the Pi shut down at high power consumption levels, suggesting issues beyond frequency limits. Changing the crystal oscillator also did not allow it to surpass 3.6 GHz. Despite hitting a frequency wall, the author gained valuable knowledge about Raspberry Pi overclocking and hardware modifications. This experience serves as a foundation for future experiments, with thanks to ElmorLabs for support.
