The si3112r.sys process is a component system file deployed alongside other system drivers, modular DLL resources and program files that are required by the Silicon Image SiI software, which is a program classified as part of the firmware and driver software components of certain motherboards that are integrated with certain Silicon Image chipsets. The si3112r.sys process is packaged with the installer distributions of these Silicon Image firmware and driver software resources. This also means the si3112r.sys file is placed in the system alongside other associated program files, system drivers and modular DLL components that are used by these Silicon Image devices upon the installation of these Silicon Image firmware and driver software resources. The si3112r.sys file is specifically implemented as one of the components of the Serial ATA RAID Miniport Driver module, which is an applet that is built into the Silicon Image SiI software.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. si3112r.sys. is used by Silicon Image SiI and Silicon Image Serial ATA RAID Miniport Driver Module, If you shut down si3112r.sys, it will likely start again at a later time either after you restart your computer or after an application start. To stop si3112r.sys, permanently you need to uninstall the application that runs this process which in this case is Silicon Image SiI and Silicon Image Serial ATA RAID Miniport Driver Module, from your system.

After uninstalling applications it is a good idea to scan you Windows registry for any left over traces of applications. Registry Reviver by ReviverSoft is a great tool for doing this.

A process usually a part of an installed application such as Silicon Image SiI and Silicon Image Serial ATA RAID Miniport Driver Module, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.
