Disclosed is a mainboard supporting a hybrid memory, which includes a first connector, a second connector, and a voltage regulation circuit connecting with the first connector and the second connector, the first connector is used to install the first type memory, the second connector is used to install the second type memory, when the first or the second type memory are installed at the corresponding connector, the connector provided with the corresponding memory generates an identification signal, the voltage regulation circuit judges the type of the memory installed on the mainboard, and provides a suitable working voltage for the type of memory. The mainboard supporting the hybrid memory can support different types of memories elastically, so the demands of different users can be satisfied.
