The invention discloses a method for setting a VR chip address based on a gate circuit chip. The method specifically comprises the following steps: firstly, accessing to a memory board from a CPU board through resistors and a high-speed connector in sequence, and realizing a decoder on the memory board by using a phase inverter and an AND gate, wherein the output of the decoder acts with the resistors together as input of 12C Address of a VR chip. Compared with the prior art, the method for setting the VR chip address based on the gate circuit chip can be used when the CPU board is connected with a plurality of memory boards and BMC accesses to VR chips of different models on the memory boards by using I2C of a same path in a conflict-free manner, is beneficial to reuse of memory boards, and is high in practicability and easy to popularize, the hardware development cost can be lowered, and the hardware principle design can be simplified.
