In relation to PC associated DIY enthusiasm, it is arduous to go previous the Raspberry Pi group. This bank card sized, low cost because the potato number of chips laptop has been lending itself to spectacular initiatives for years. Whether or not you wish to construct your very personal merchandising machine (opens in new tab), have a spy prepared backpack (opens in new tab), or a cat powered doorbell (opens in new tab), the Pi is the proper companion for all these initiatives.
However we dwell on the planet we do, so some individuals simply aren’t proud of what this little miracle of a pc can obtain. It isn’t sufficient that one thing that may slot in my pockets can obtain clock speeds of as much as 1.5GHz. Somebody simply needed to go and push the boundaries on this poor little trooper, and boy did they.
Tom’s Hardware (opens in new tab) noticed this unimaginable feat of delidding hubris, the place Ivan “Merocle” Huleshov (opens in new tab) managed to get clock speeds as much as 2.5GHz on a Raspberry Pi. To attain this, Huleshov took a Compute Module 4 Raspberry Pi, and really rigorously took a knife to take the highest off the CPU, then utilized some critical cooling to maintain it secure. You will get a take a look at the method in his YouTube video which can be on the high of this text, or take a look at the Reddit thread (opens in new tab).
The Compute Module 4 Raspberry Pi (opens in new tab) is a good selection for beginning builds that do not want all the additional stuff that comes with the usual Raspberry Pi 4. It permits for a provider board to be linked to customize your energy decisions and permit to be used of a PCIE slot. It would not appear like Huleshov is making a lot use of that right here thoughts, as a substitute he is simply pushing this Pi to its absolute limits, only for enjoyable.
Whereas the clock velocity is spectacular, it is not unprecedented. Overclocker Claude Schwarz achieved a 3GHz clock velocity (opens in new tab) on the identical machine, however solely managed to keep up it with an ice spray for coolant, and probably some reprogramming. Whereas Huleshov’s try seems way more secure, and solely requires a 5 strains config.txt file, it equally nonetheless requires a helluva lot of chill to run.
For the Raspberry Pi to keep up stability at these speeds, Kuleshov explains (opens in new tab) that the temperature should be stored underneath 6 levels Celsius. That is 42 Fahrenheit, or just a bit over freezing temperature. That is going to require a reasonably good cooling setup if you wish to get that secure 2.5GHz clock velocity to run.

After all, if you wish to obtain the identical lofty clock speeds, you will wish to be extremely cautious. Delidding a CPU voids any guarantee, and may usually go unsuitable resulting in a very damaged system. The great value level of a Raspberry Pi makes it a cheap observe software, however the tiny board additionally provides its personal challenges. Nonetheless, it is at all times spectacular to see simply how arduous a chip might be pushed, be it a Raspberry Pi or a Ryzen Threadripper Professional, with a pleasant serving to of liquid nitrogen (opens in new tab).
