The operating unit is a memory unit, and the rated frequency value is a memory unit frequency value of the memory unit.

Please refer to FIG. 1 , which is a block diagram of a display card frequency control system according to a first embodiment of the present invention. The display card frequency control system 10 in the first embodiment has a central processing unit 11, an external power supply unit 13, and a display card 12.

The central processing unit 11 is, for example, a central processing unit (CPU) of a desktop computer. The central processing unit 11 has an overclocking adjustment module 110. The overclocking adjustment module 110 is configured to generate an operation command 1101. More specifically, the overclocking adjustment module 110 is a software program or a firmware for adjusting an operating frequency of the operating unit 124 of the display card 12, such as a commercially available OC-GURU series software (available by Gigabyte Some companies have purchased it). The overclocking adjustment module 110 can be built into a desktop computer.

The external power supply unit 13 is, for example, a power supply device that can be used by the desktop computer motherboard, for example, a 2*3 or 2*4 ATX power supply, and can provide the working power supply 131 when the display card 12 is overclocked. . More specifically, the 2*3 ATX power supply can provide approximately 87W of power. The 2*4 ATX power supply provides approximately 162W of power. The external power supply unit 13 is electrically connected to the central processing unit 11.

The display card 12 has an external power supply interface 120, a control unit 122, and an operation unit 124. The external power supply interface 120, the operation unit 124, and the central processing unit 11 are electrically connected to the control unit 122 individually. In this embodiment, the external power supply interface 120 is, for example, a power connector corresponding to a PCI-E slot on a computer motherboard, and can be directly or indirectly electrically connected to the external power supply unit 13. An overclocking adjustment receiving module 1220 is disposed in the control unit 122 for receiving an operation command 1101 from the overclocking adjustment module 110. The operating unit 124 is, for example, a graphics processor or a memory unit. In general, a display card in an embodiment typically also has a RAMDAC, a VGA BIOS, a VGA function pin, a VGA socket, and other peripheral components. In other embodiments, the display card also has a DVI display interface or an HDMI interface and an S-Video terminal interface.

Referring to FIG. 1 and FIG. 2 together, FIG. 2 is a flow chart showing a frequency control method of the display card frequency control system according to the first embodiment of the present invention. First, in step S200, the control unit 122 determines whether the display card 12 is in a heavy load state. In another embodiment, the control unit 122 can also be controlled by the central processing unit 11 to determine whether the display card 12 is in a heavy load state.

When the control unit 122 determines that the display card 12 is not in the reload state (in other words, when the display card 10 is in a non-heavy state), the control unit 122 performs the control operation unit 124 to perform a normal frequency mode 1241, as shown in step S210. .

When the display card 12 is in a heavy load state, the control unit 122 determines whether the external power supply interface 120 has been externally connected to the external power supply unit 131, as shown in step S230. If so, it means that the control unit 122 determines that the external power supply interface 120 has been externally connected to the external power supply unit 131, and as shown in step S233, the overclocking adjustment module 110 of the central processing unit 11 generates an operation command 1101. More specifically, through the overclocking adjustment module 110, for example, the OC-GURU software passes through the human machine interface, so that the user can adjust the operating frequency of the operating unit 124 of the display card 12 through the movement of the field. Down-frequency or over-clocking, and then the self-adjustment of the highest critical over-frequency parameter of the operating frequency, and the operation command 1101 is generated corresponding to the operating frequency. Further, as in step S234, the control unit 122 controls the operation unit 124 to execute an overclocking mode 1243.

Referring to step S230 again, the control unit 122 determines whether the external power supply interface 120 is externally connected to the external power supply unit 131. If not, the control unit 122 determines that the external power supply interface 120 is not externally connected to the external power supply unit 131, and then proceeds to step S232 (shown by a solid line frame), and the control unit 122 controls the external power supply interface 120 to be electrically connected to the external power supply unit 13. After the external power supply interface 120 is electrically connected to the external power supply unit 13, the subsequent step S233 is performed.

In another embodiment of the present invention, a step S231 (dash box representation) may also be included. Referring to step S230, the control unit 122 determines whether the external power interface 120 is externally connected to the external power supply 131. If not, the control unit 122 determines that the external power supply interface 120 is not externally connected to the external power supply 131, and then proceeds to step S231, and the overclocking adjustment module 110 of the central processing unit 11 generates a prompt signal 1103. The prompt signal 1103 is, for example, a bounce window. Thereby, the user can be reminded that the external power source has not been connected, and then the user can decide whether or not the external power source is externally connected, and then the control unit 122 proceeds to step S232.

Please refer to FIG. 2 and FIG. 3 again. FIG. 3 is a flow chart of a first embodiment method based on the frequency control method of FIG. In the step S230 shown in FIG. 2, the control unit 122 determines whether or not a specific embodiment of the external external power supply unit 13 is step S330 as shown in FIG. The control unit 122 determines whether the operating power amount of the display card 12 has exceeded the estimated power supply amount required for the overclocking by the operation unit 124, and if so, determines that the external power supply unit 13 has been externally connected, and proceeds to step S233. If not, it is determined that the external power supply unit 13 is not externally connected, and the process proceeds to step S232 (shown in solid frame) or step S231 (indicated by virtual frame).

Referring to FIG. 4 again, FIG. 4 is a flow chart of a second embodiment method based on the frequency control method of FIG. The second embodiment of the frequency control method of FIG. 4 differs from the first embodiment of the frequency control method of FIG. 3 in that, after proceeding to step S232, the process proceeds to step S330 again, and is further determined by the control unit 122.

In addition to meeting the needs of users, it can also reduce power consumption and save energy. In addition, when the display card 12 is in the heavy load state, the control unit 122 controls the display card 12 to be externally connected to an external power supply 133, and then through the external power supply 133 to provide an additional amount of power required for overclocking of the operating unit 124. Overall, the operating frequency of the display card 12 is more flexible, thereby achieving the effect of saving power. In addition, the service life of the display card 12 can be extended, thereby improving the efficiency of use of the computer. Moreover, in the display card frequency control system of the first embodiment, it is not necessary to design an additional overclocking hardware and hardware type warning device, but the overclocking adjustment module is used to adjust the operating frequency of the operating unit.

The present invention is not limited to the display card frequency control system of the first embodiment described above and its corresponding frequency control method, in other words, as long as the control unit that transmits the display card is based on the light load (non-heavy state) or the heavy load state of the display card.

When the control unit 122 determines in step S330 that the operating power amount of the display card 12 does not exceed the estimated power amount when the operating unit 124 overclocks ( That is, when it is judged that the external power supply unit 13 is not externally connected, the control unit 122 will control the operation unit 124 to execute the original operation mode. More specifically, as steps In S931, the control unit 122 determines whether the external power supply 13 is required, and if so, proceeds to step S232. If not, then proceeding to step S932, the control unit 122 controls the operation unit 124 to execute the original operation mode (for example, the original frequency mode as in step S210).

Please refer to FIG. 10, which is a block diagram of a display card frequency control system according to a third embodiment of the present invention. The display card frequency control system 10 in the third embodiment has a central processing unit 11, an external power supply unit 13, and a display card 12.

The central processing unit 11 has an overclocking adjustment module 110, and its function is substantially the same as that of the first embodiment, and the same portions will not be described again. Hereinafter, only the difference portion will be described.

The external power supply unit 13 is, for example, a power supply device for providing the desktop computer motherboard. The external power supply unit 13 has a plurality of working power sources 132a, 132b, and each of the working power sources 132a, 132b has a maximum output power. At the same time, the ATX power supply with the working power source 132a of the 2*3 connector and the working power source 132b of the 2*4 connector can provide the working power sources 132a, 132b required when the display card 12 is overclocked. More specifically, the 2*3 connector's operating power source 132a can provide approximately 87W of power to accommodate light overclocking requirements. The 2*4 connector's operating power supply 132b provides approximately 162W of power and is suitable for heavy overclocking needs. The two working power sources 132a, 132b of the present embodiment are merely illustrative, and are not intended to limit the number of operating power sources 132a, 132b. Actually, the number of working power sources may be two or more.

The display card 12 has an external power supply interface 120, a control unit 122, and an operation unit 124. The functions of the display card 12 are substantially the same as those of the first embodiment, and the same portions will not be described again. Hereinafter, only the difference portions will be described.

As shown in FIG. 10, in the third embodiment, the external power supply interface 120 is selectively connectable to one of the plurality of operating power sources 132a, 132b of the external power supply, or is completely Not connected to the working power sources 132a, 132b.

Referring to FIG. 10 and FIG. 11 together, FIG. 11 is a flowchart of a frequency control method of the display card frequency control system according to the third embodiment of the present invention.

First, in step S200, the control unit 122 determines whether the display card 12 is in a heavy load state. In another embodiment, the control unit 122 can also be controlled by the central processing unit 11 to determine whether the display card 12 is in a heavy load state.

When the control unit 122 determines that the display card 12 is not in the reload state (in other words, when the display card 10 is in a non-heavy state), the control unit 122 performs the control operation unit 124 to perform a normal frequency mode 1241, as shown in step S210. .

When the display card 12 is in a heavy load state, the control unit 122 determines whether the external power supply interface 120 has been externally connected to the external power supply unit 131, as shown in step S230. If so, it means that the control unit 122 determines that the external power supply interface 120 has externally connected one of the working power sources 132a, 132b of the external power supply unit 131, and further, as shown in step S233.

Next, the control unit 122 determines the maximum output power of the working power sources 132a, 132b according to the working power sources 132a, 132b connected to the external power supply interface 120. The manner of determination can be determined by the number of phases of the output power of the operating power sources 132a, 132b, as shown in step S230a.

Then, the control unit 122 determines an upper limit of the operating frequency according to the maximum output power, as shown in step S230b.

The overclocking adjustment module 110 of the central processing unit 11 will generate an operational command 1101. More specifically, the overclocking adjustment module 110, for example, the OC-GURU software passes through the human machine interface, thereby being able to automatically adjust the highest critical overclocking parameter of the operating frequency, and generates an operation command 1101 corresponding to the operating frequency; based on step S230b Set, the operating frequency will not be greater than the Operating frequency upper limit. Further, in step S234, the control unit 122 controls the operation unit 124 to execute a corresponding overclocking mode 1243, 1245 according to the upper limit of the operating frequency.

For example, when the working power supply 132a of the 2*3 connector is connected, the maximum output power is relatively small (87W), so the corresponding upper limit of the operating frequency is also lowered, so that the overclocking mode in which the operating frequency is not to be greater than the upper limit of the operating frequency is required. 1243. When the working power source 132a of the 2*4 connector is connected, the maximum output power is relatively large (162W), so the corresponding upper limit of the operating frequency can also be increased, so that the overclocking mode 1245 whose operating frequency is not greater than the upper limit of the operating frequency can be selected.

In this way, the overclocking mode 1243, 1243 can be adjusted according to the actual maximum output power of the external working power sources 132a, 132b to achieve the best overclocking effect.

Referring to step S230 again, the control unit 122 determines whether the external power supply interface 120 is externally connected to the external power supply unit 131. If not, the control unit 122 determines that the external power supply interface 120 is not externally connected to the external power supply unit 131, and then proceeds to step S232 (shown by a solid line frame), and the control unit 122 controls the external power supply interface 120 to be electrically connected to the external power supply unit 13. After the external power supply interface 120 is electrically connected to the external power supply unit 13, the subsequent step S233 is performed.

The third embodiment may also include a step S231 (indicated by a dashed box), which is substantially the same as the first embodiment, and details are not described herein again.

Please refer to FIG. 13, which is a block diagram of a fourth embodiment of the display card frequency control system of the present invention.

The control unit 222 has a plurality of overclocking modules 2220a, 2220b and an original frequency module 2222. The overclocking modules 2220a, 2220b and the original frequency module 2222 can each be a firmware, such as a GPU BIOS of a display card. The switch 224 is electrically connected between the external power interface 120 and the control unit 222 for selectively switching to one of the overclocking modules 2220a, 2220b or the original frequency module 2222. The changeover switch 224 is, for example, a field effect transistor.

Referring to FIG. 13 and FIG. 14 together, FIG. 14 is a flowchart of a frequency control method according to a fourth embodiment of the display card frequency control system of the present invention. First, as shown in step S600, the control unit 222 determines whether the display card 22 is in a heavy load state.

If not, that is, the display card 22 is in a non-heavy state or not in the heavy state, the step S610 may be continued, the switch 224 is connected and/or switched to the original frequency module 2222, and the control unit 222 controls the operation unit 124. The original frequency mode 1241 is executed.

On the other hand, if it is, that is, when the display card 22 is in a heavy load state, step S630 is performed. The control unit 222 determines whether the external power supply interface 120 is externally connected to an external power supply unit 13. If so, the control unit 222 determines that the external power supply interface 120 has externally connected to one of the working power sources 132a, 132b of the external power supply unit 13.

Next, the control unit 222 determines the maximum output power of the operating power sources 132a, 132b according to the connected operating power sources 132a, 132b, as shown in step S630a.

The control unit 222 determines an upper limit of the operating frequency according to the maximum output power, as by step S630b.

Step S633 is continued, according to the upper limit of the operating frequency, switching and/or connecting to one of the two overclocking modules 2220a, 2220b, wherein each of the overclocking modules 2220a, 2220b, and Control unit 222 will control one of overclocking modes 1243, 1245 to control operating unit 124.

For example, when the working power source 132a of the 2*3 connector is connected, the maximum output power is relatively small (87W), so the corresponding upper limit of the operating frequency is also lowered; at this time, the control unit 222 switches to the overclocking mode corresponding to the low power. Group 2220a, according to the corresponding low power overclocking module 2220a, the operating unit 124 also performs a low power overclocking mode 1243.

Conversely, when the working power supply 132b of the 2*4 connector is connected, the maximum output power is relatively high (162 W), so the corresponding upper operating frequency limit is also provided; at this time, the control unit 222 is switched to the corresponding high power overclocking mode. Group 2220b, according to the corresponding high power overclocking module 2220b, the operating unit 124 also performs a high power overclocking mode 1245.

In the embodiment of the method, the frequency control method further has a step S632, but is not limited thereto. Referring to step S630 again, the control unit 222 determines whether the external power interface 120 is externally connected to the external power supply unit 13. If not, it represents The control unit 222 determines that the external power supply interface 120 is not externally connected to the external power supply unit 13, and then proceeds to step S632, the switch 224 is switched and/or connected to the original frequency module 2220, and the control unit 222 controls the operation unit 124 to execute the original Frequency mode 1241.
