The present application discloses a method and device for recovering self-test exception of a server component, a system and a medium. The method includes the following steps: acquiring self-test exception state data sent by a platform control center when a target component in a server has a self-test exception; querying corresponding first firmware data and second firmware data from the first flash memory chip and the second flash memory chip based on the self-test exception state data; determining whether the first firmware data is consistent with the second firmware data; and determining target firmware data for self-test exception recovery based on the first firmware data and the second firmware data if the first firmware data is consistent with the second firmware data, and sending the target firmware data to the platform control center, so that the platform control center performs self-test exception recovery by using the target firmware data.

Disclosed are a power consumption reduction circuit for Graphics Processing Units (GPUs) in a server and a server. The power consumption reduction circuit includes a frequency reduction control chip. The frequency reduction control chip, after receiving an overpower alarm signal generated by a Power Supply Unit (PSU), generates a frequency reduction control signal to a Power Break (PWRBRK) pin of each GPU so as to start a frequency reduction operation of each GPU. It can be seen that, in the present application, an underlying hardware circuit is directly used for implementation with relatively quick responses and without intervention of an operating system, whereby the whole frequency reduction operation of the GPU may be completed within 5 ms, and the PSU is prevented from triggering overpower protection within relatively short time. Therefore, loss of service data of a user caused by an exceptional power failure of the server is avoided.
