Raspberry Pi has given rise to many interesting projects, but passive cooling and other technical details limited the potential of overclocking in the computer. To be relatively economical, there are enthusiasts beyond outside who have no problem taking a Pi to the limit, even if that means to perform modifications to hardware, or destroying it full . However, sometimes the risks have their reward, and the Brazilian portal EverPi showed him claiming first place in HWBOT with a Raspberry Pi Zero cooled by Peltier to 1,600 MHz .
overclocking is something quite popular on the Raspberry Pi platform, despite the restrictions affecting the hardware. Market offers several covers special to optimize cooling and include small coolers, but who want extreme results must be more than of an aluminum block and a fan. If studied closely in HWBOT results table the ceiling for Raspberry Pi in all its models is about 1,600 MHz. Almost three years ago, user RRainbo it reached first place with 1,620 MHz in a Raspberry Pi + 1 B, but as we all know well, HWBOT assigned positions according to the validated score.
this fact leads us to the door of the portal EverPi which recorded a total of 855.04 points with a frequency of 1600 MHz in a Raspberry Pi Zero . The key to achieving that speed was fed directly to the processor, since the control software does not exceed the 1.4V. EverPi left a small inductor for the road and introduced a LM2596 controller for better control above 2v. Your cooling solution (y el SoC en sí) found a limit to 2. 08v, therefore the solution was customized to the sink, adding a Peltier module side hot dipped in ice water. SoC temperature fell to 2.4 degrees Celsius, and the condensation was critical, but at the time of running HWBOT became a stable 16 degrees.
In theory, the Raspberry Pi Zero could pierce the barrier of 1,600 MHz (después de todo, comparte el mismo chip con el Raspberry Pi 1 B+) but requires a modification of low level in their firmware that is not yet available. Until that happens, Brazil is in the lead.
