Abstract: A computer device, a setting method for a memory module, and a mainboard are provided. The computer device includes a memory module, a processor, and the mainboard. A basic input output system (BIOS) of the mainboard stores a custom extreme memory profile (XMP). When the processor executes the BIOS, so that the computer device displays a user interface (UI), the BIOS displays multiple default XMPs stored in the memory module and the custom XMP through the UI. The BIOS stores one of the default XMPs and the custom XMP to the memory module according to a selecting result of the one of the default XMPs and the custom XMP displayed on the UI.

Abstract: An automatic device for replenishing the liquid oil and the like is composed of an oil container, a cap, an oil injecting seat, an oil blocking body, and a connection seat. The oil container is provided at the bottom thereof with a joint fastened therewith rotatably. The oil injecting is located in the joint and is provided at the bottom thereof with a cut. The connection seat is fastened at the top end thereof with the joint. When the oil consumption has reached an extent that the cut of the oil injecting seat and the oil level surface form therebetween a gap, the atmospheric air is drawn into the connection seat through which the atmospheric air flows into the joint via the gap, thereby resulting in an automatic replenishing of the oil. As soon as the gap is eliminated, the atmospheric air is kept out of the connection seat so as to bring about an end to the replenishing process of oil.
