Description

technical field [0001] This application relates to the technical field of blockchain equipment manufacturing, and in particular to a method and device for controlling a computing power board, as well as digital certificate processing equipment, storage media, and computer program products. Background technique [0002] For digital credential processing equipment, the core idea of ​​improving its performance is to maximize its computing power and obtain a maximum computing power within the computing power range of the entire computing power board. That is to allow some bad chips to run in an unstable state, but at the same time greatly explore the computing power of high-quality chips, and then seek an overall optimal.

AI Technical Summary

Problems solved by technology

[0003] However, for hash boards designed in series with voltage domains, it is easy to have insufficient voltage division in individual voltage domains, which will lead to failure of chips in this voltage domain, such as instability or abnormal operation, resulting in unreasonable power loss

Even the failure of a single chip will lead to the failure of all chips in the voltage domain where the chip is located. At this time, the power consumption is basically unchanged, and the energy efficiency ratio is rapidly deteriorated.
