Raspberry Pi can now be officially overclocked to 1 GHz without losing the warranty

Yesterday the Raspberry Pi Foundation officially announced the possibility of increasing the initial frequency of the Raspberry Pi processor from 700 MHz to 1 GHz without losing the warranty on the device due to the inclusion of a special “turbo mode”.

The developers have done several studies evaluating how the increase in voltage and temperature affects the life of the processor and, as it turned out, the “turbo mode” can be dynamically turned on by the CPU driver and turned off when its temperature reaches 85 ° C; at the same time, there is no significant impact of equipment wear.

The corresponding parameters are already included in the raspi-config of the latest Raspbian Linux image. In general, increasing the CPU frequency to the highest declared official frequency of 1 GHz (in principle, you can set a larger value, but in this case Raspberry may not load) causes integer calculations to become 52% faster, floating point calculations by 64%, and the speed of access to memory increases by 55%.
