It’s like destructive impact testing for cars, reveals hardware limits today and let us prepare improvement direction for future products. It’s also a measure for reliability, as better overclocking means there is more safety margin available in the design. Overclocking is not useless as many think, it gives us a glimpse of what can be achieved by better manufacturing process and higher performance parts now, without waiting for the developers and fabs to make actual improved parts. Process of increasing processor speed called overclocking, which is known for few decades already, since the beginning of the digital computing. That comes at price of increased power consumption and possibly, reducing stability as erroneous operation is more likely under stress. One of the common ways to get performance gains are increasing running frequency of the processor, memory and storage interface. In this article we are not covering interfacing or data processing ability of Raspberry Pi SBC, but rather attempt to squeeze some more performance out it. Image 1: Raspberry Pi 3 computer with its retail package It is not new, other people were already successfully overclocking their Pi1’s years ago, yet it’s still fun to do. Overclocking is not limited just to personal computer, same concept applies well for nearly any digital system, including mobile processors and embedded SOC devices, such as Raspberry Pi 3. Hardcore overclockers even create demand for special power supply modules that allow use of higher voltages to gain that last bit of performance possible. To explain some concepts and design features that help users to achieve better overclocking many detailed OC guides were posted, such as here or here. After few years of pushing performance of desktop computer as a hobby it become part of my daily profession, designing products that implement overclocking features and ability at their core, such as high-performance PC graphic cards and high-performance motherboards for Intel CPUs. Overclocking can take many forms and shapes, from useful everyday boost of few hundred MHz (think of tuning car engine to get better acceleration performance) to insane cryo-cooled rigs for international OC competitions (drag-racing cars with jet engines, no less). I’m well used to traditional desktop computer performance tuning and overclocking as a hardware enthusiast. Separate traditional PC or even laptop for such needs would occupy too much space, power and programming effort, as low level interfaces such as I 2C, SPI are rarely available without additional hardware. Low cost (around $40 USD for fully-featured Raspberry Pi 3) and compact size allow easy adding of standalone modules for running different experiments, and invisible to total project budget since involved test equipment often costs many times more. Here at various versions of Raspberry Pi are already widely used as test equipment controllers and live data-logging platform. Software developers now can build own devices without even touching the soldering iron.Ĭompact (85 × 56 mm) Raspberry Pi single-board computer represent this concept as affordable educational platform. Modern ARM-based systems have all the means to run fully-featured Linux OS, and allow quick start on own project development even without any background knowledge in hardware design. ARM today is one of the most popular architectures in embedded systems and used in many applications and fields.
