Abstract
A method for achieving power saving for computers through memory throttling by adding the appropriate program codes into the BIOS, so that the invention may set the register of a north bridge chip according to the needs of the user, and enable or disable the memory throttling function provided by the chipset.
Claims4
A method of achieving power saving for a computer through memory throttling, using a basic input/output system (BIOS) to setup a chipset for providing the function of memory throttling;
- such method of achieving power saving for a computer through memory throttling comprises the steps of:
- reading a set of user setup values from a non-volatile random access memory, (NVRAM);
- setting a register according to the user's setup value;
- executing a power-on self test (POST);
- calling a processing-suspending program to issue a suspension request;
- displaying a setup screen with options;
- storing a new set of user setup values to the NVRAM;
- rebooting the system;
- and
- turning over a controlling authority to an operating system (OS);
- wherein the function of the memory throttling is used to reduce a bandwidth of memory throughput;
- wherein the user's setup value may enable or disable the memory throttling;
- and
- wherein the register is a register of a north bridge.
