EverPi manages to make a Raspberry Pi work at 1.600 Mhz

Everpi

Many are the enthusiasts who day by day try to get further by taking a Raspberry Pi as a starting point. Thanks to this we have very interesting and theoretically simple projects to carry out and even very crazy ideas like the one I present to you today. Everpi a Brazilian portal specialized in this controller, has achieved that, thanks to its community, one of its cards can work at no less than 1.600 Mhz.

As you are surely thinking, we are talking about a new way of performing overclocking to the card, something that on the other hand is a technique that many users follow to get more power for their applications although, as you can imagine, in fact those responsible for EverPi announce that it is the most powerful project presented to date, it is not a simple technique, especially at these extremes.

To improve the 1.600 Mhz achieved by EverPi, firmware level modifications would be needed.

To get this frequency on a Raspberry Pi, the guys at EverPi had to perform different hardware modifications for, among other occasions, to be able to feed the processor directly because the software control installed on the board does not allow more than 1.4v. This work could be carried out by eliminating a small inductor that is responsible for this control and introducing, in its place, an LM2596 regulator to improve control over powers greater than 2v.

As you are probably thinking, this entire system requires a complex cooling system, something that was achieved by installing a completely customized heatsink to which a Peltier module whose hot side was directly immersed in ice water. Thanks to this, EverPi comments that it was possible to lower the temperature to 2.4 degrees celcius, which subsequently stabilized at a more than interesting 16 degrees celcius.
