BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention provides a method for adjusting an operating rate of a graphics card, and more particularly, a method for adjusting the operating rate safely.

2. Description of the Prior Art

As multimedia technology improves, the efficiency of graphics displays in a computer system increases a lot. Generally, in order to ensure a workable graphics card, graphic-card manufacturers set parameters of the graphics card with a safety setting, such as a lower operating rate. Therefore, in the graphics card, a timing and a voltage for a graphics processing unit (GPU) chip are much lower than the maximum timing and voltage that the GPU chip can bear. In order to get different performances, a user can increase or decrease the operating rate of the graphics card. For example, when playing a PC game, the user can increase the operating rate of the graphics card to get a better performance, while when using two-dimensional software, a lower operating rate is sufficient to satisfy the user's desired performance. However, there are no systematic and safe methods for changing the operating rate of the graphics card in the prior art, so the user can only use trial and error to find an optimal setting for the graphics card, which wastes time, easily fails, and may damage the graphics card.

DETAILED DESCRIPTION

Please refer toFIG. 1, which illustrates a flowchart of a process100for increasing an operating rate of a graphics card in accordance with the present invention. The process100includes following steps:

Step104: raise a rotation rate of a radiator fan of a GPU chip of the graphics card to a first rotation rate according to a rate increasing command.

Step106: raise a voltage inputted to the GPU chip to a first voltage, and raise a voltage inputted to a memory of the graphics card to a second voltage when the rotation rate of the radiator fan is approximately equal to the first rotation rate.

Step108: raise a timing of the GPU chip to a first timing, and raise a timing of the memory to a second timing when the voltage inputted to the GPU chip is approximately equal to the first voltage, the voltage inputted to the memory being approximately equal to the second voltage.

Therefore, according to the process100, before increasing an operating rate of a graphics card, the present invention raises a rotation rate of a radiator fan of a GPU chip, so as to keep the GPU chip from becoming hotter when a timing and a voltage inputted to the GPU chip jumps up suddenly. After the rotation rate is raised, voltages of the GPU chip and a memory are increased to meet a higher timing of the GPU chip. Finally, as both of the rotation rate and the voltages are raised, the timings of the GPU chip and the memory are raised. In other words, the present invention process100changes the graphics card to a status that can meet a higher operating rate, and then raises the timings of the GPU chip and the memory. Therefore, the present invention can increase the operating rate easily and safely.

Oppositely, decreasing the operating rate of the graphics card can be performed in inverse of the process100. Please refer toFIG. 2, which illustrates a flowchart of a process200for decreasing an operating rate of a graphics card in accordance with the present invention. The process200includes following steps:

Step204: decrease a timing of a graphics processing unit chip of the graphics card to a first timing, and decrease a timing of a memory of the graphics card to a second timing according to a command of decreasing rate.

Step206: decrease a voltage inputted to the graphics processing unit chip to a first voltage, and decrease a voltage inputted to the memory to a second voltage when the timing of the graphics processing unit chip is approximately equal to the first timing.

Step208: decrease a rotation rate of a radiator fan of the graphics processing unit chip to a first rotation rate when the voltage inputted to the graphics processing unit chip is approximately equal to the first voltage, the voltage inputted to the memory being approximately equal to the second voltage.

Therefore, according to the process200, when decreasing an operating rate of a graphics card, the present invention decreases timings of a GPU chip and a memory first, then decreases voltages of the GPU chip and the memory, and finally, decreases a rotation rate of a radiator fan of the GPU chip. As a result, the radiator fan runs with a lower rotation rate, so as to decrease noise caused by wind shear.

In short, the higher the display efficiency of a graphics card is, the higher the operating rate of the graphics card and the temperature of a GPU chip in the graphics card will be. Therefore, the GPU chip must include a radiator mechanism, such as a radiator fin, a radiator fan, etc., for preventing the GPU chip from overheating and being damaged. However, a high-speed radiator fan generates loud noise. When a user wants to use the computer system quietly, the present invention process200can decrease the operating rate of the graphics card and the rotation rate of the radiator fan, so as to decrease noise.

In the present invention, the process100can increase an operating rate of a graphics card safely, while the process200can decrease noise of a computer system. Therefore, according to the processes100and200, the present invention further provides a method for adjusting an operating rate of a graphics card. Please refer toFIG. 3, which illustrates a flowchart of a process300for adjusting an operating rate of a graphics card in accordance with the present invention. The process300includes following steps:

Step304: provide a plurality of parameter settings according to hardware of the graphics card.

Step306: adjust the operating rate of the graphics card according to a first setting and an original timing of a graphics processing unit chip of the graphics card when the first setting is selected.

Therefore, the present invention300sets a plurality of settings according to hardware of a graphics card. When a user selects one of the settings, the present invention adjusts the graphics card according to the selected setting and the original setting of the graphics card. For example, please refer toFIG. 4, which illustrates a table400of settings for a graphics card in accordance with an embodiment of the present invention. The table400includes columns describing timings of a GPU chip and a memory, voltages of the GPU chip and the memory, and a rotation rate of a radiator fan. According to different operation demands, the table400provides five settings. For example, a setting3is a basic setting corresponding to normal users, a setting1is an ultrahigh frequency setting corresponding to high 3D efficiency, and a setting5is a silence setting for decreasing the rotation rate of the radiator fan. A setting2is the setting between the settings1and3, while a setting4is the setting between the settings3and5. Once the user selects one of the settings, the process300inspects the selected setting and the current setting of the graphics card, so as to increase the operating rate of the graphics card according to the process100, or to decrease the operating rate of the graphics card according to the process200. For example, if the original setting of the graphics card is the setting3. When a user selects the setting1for getting higher 3D efficiency, the process300increases the operating rate of graphics card according to the process100, so the rotation rate of the radiator fan will be raised first, then the voltages of the GPU chip and the memory, and finally the timings of the GPU chip and the memory. Oppositely, if the user changes settings from the setting1to the setting5, the process300decreases the operating rate of graphics card according to the process200, so the timings of the GPU chip and the memory will be decreased first, then the voltages of the GPU chip and the memory, and finally the rotation rate of the radiator fan. Therefore, for different operation demands, the present invention can fit the demands by increasing or decreasing the rotation rate of the radiator fan. Persons skilled in the art should note that the table400herein is exemplified for describing the settings of the graphics card. Various modifications could be made without departing from the spirit of the present invention.

Moreover, when adjusting the operating rate of the radiator fan, if the radiator fan cannot reach the expected speed, the present invention can decrease the timing of the GPU chip and the memory to a safe timing, and alarm the user that the radiator fan is abnormal. Furthermore, according to the temperature of the GPU chip, the present invention can fine-tune the rotation rate of the radiator fan.

In summary, the present invention provides a method for increasing the operating rate of the graphics card safely, and a method for decreasing noise generated by the graphics card. Therefore, users can choose settings for getting more 3D efficiency or a silent surrounding.
