Mining machine fast frequency search method and device and mining machine

Abstract

The invention discloses a mining machine fast frequency search method and device as well as the mining machine. The method includes: under the initial output voltage of the power supply of the mining machine, the frequency of the computing chip is gradually increased from the initial frequency point through at least one first frequency point to the target frequency, wherein the duration of the operation chip at each first frequency point is shorter than the duration of the operation chip at each first frequency point in the conventional frequency search process; when the operation chip reaches the target frequency, according to at least An output voltage value and at least one second frequency point, combined with the test tasks issued to the computing chip and the feedback results of the computing chip, the output voltage of the power supply of the mining machine and the frequency of the computing chip are adjusted to obtain the limit frequency of the computing chip and The output voltage of the mining machine power supply corresponding to the limit frequency. The present invention shortens a large amount of frequency search time, saves power consumption of frequency search, and the saved time is used for mining calculation of mining machines to further improve mining efficiency.

Description

technical field [0001] The invention relates to the technical field of virtual currency mining machines, in particular to a mining machine fast frequency search method and device and a mining machine using the device. Background technique [0002] In the existing virtual currency mining machines, the working mode of fixed frequency and fixed voltage is adopted, that is, the calculation chip in the mining machine adopts the fixed working frequency set in advance, and the output voltage of the power supply of the mining machine adopts the fixed voltage set in advance. In this way, in order to ensure the normal operation of the mining machine, the output voltage of the power supply will have a certain redundancy, and the fixed operating frequency of each computing chip is not its limit operating frequency. Although this setting can ensure the normal operation of the mining machine, the redundant voltage causes a waste of mining machine power and increases the useless power cons...

Problems solved by technology

However, since the operation of the mining machine is also affected by the temperature, too high or too low temperature is not conducive to the performance of the computing power of the mining machine. During the frequency search process, it is also necessary to consider that the temperature of the mining machine will gradually increase with the increase of the frequency of the computing chip. High, so there is a process of waiting for the temperature of the mining machine to increase synchronously during the frequency search process. This process takes up a lot of time, making the frequency search process too long. The frequency search process after the mining machine is turned on often takes about 30 minutes. , and the mining machine cannot provide normal computing power during the frequency search process. If there is a frequent start-up of the mining machine, it will greatly reduce the normal mining time of the mining machine, thereby reducing the mining machine and the mine as a whole. s efficiency
