Abstract

A motherboard an electronic device using the same are provided. The motherboard includes a motherboard and a control chip. The processor is adapted to be inserted to a processor base including a plurality of pins. The pins is divided to defined pins and undefined pins. The processor base includes a plurality of electrical contacts. A first part of the electrical contacts are corresponding to the defined pins, and a second part of the electrical contacts are corresponding to the undefined pins. The control chip determines whether to make the motherboard enter an overclocking operation mode according to a control command. When the motherboard is set to be at the overclocking operation mode, the control chip transmits a control signal to the undefined pins of the processor via the second part of the electrical contacts, and then the processor improves operating efficiency.

First claim

What is claimed is:

1 . A motherboard, adapted to a processor including a plurality of pins with defined pins and undefined pins, and the motherboard includes:
a processor base, including a plurality of electrical contacts, a first part of the electrical contacts are corresponding to the defined pins, a second part of the electrical contacts are corresponding to a part or all of the undefined pins; and a control chip, coupled to the processor base, transmitting a control signal to the undefined pins of the processor via the second part of the electrical contacts in an overclocking operation mode.

2 . The motherboard according to claim 1 , wherein the control chip detects load information of the processor and provides the control signal accordingly to adjust an operating parameter of the processor in the overclocking operation mode.

3 . The motherboard according to claim 2 , wherein the control chip further controls an input voltage received by the processor according to the load information to maintain the processor at a same voltage under different loads in the overclocking operation mode.

4 . The motherboard according to claim 1 , wherein the second part of the electrical contacts include a first group of the electrical contacts, which corresponds to a first group of the pins of the undefined pins.

5 . The motherboard according to claim 4 , wherein the control chip transmits a first control signal to the first group of the electrical contacts to make the processor respond to the first control signal to adjust a core ratio, a ring ratio, a memory ratio or a base clock frequency.

6 . The motherboard according to claim 5 , wherein the second part of the electrical contacts include a second group of the electrical contacts which corresponds to a second group of the pins of the undefined pins.

7 . The motherboard according to claim 6 , wherein the control chip transmits a second control signal to the second group of the electrical contacts to make the processor respond to the second control signal to adjust core ratio, the ring ratio, the memory ratio or the base clock frequency.

8 . An electronic device, comprising:
a function module; a processor, including a plurality of pins with defined pins and undefined pins; and a motherboard, coupled to the functional module and the processor, includes:
a processor base, wherein the processor is coupled to the functional module via the processor base, the processor base includes a plurality of electrical contacts, a first part of the electrical contacts are coupled to the defined pins, and a second part of the electrical contacts are coupled to a part or all of the undefined pins; and
a control chip, coupled to the processor base, transmitting signals to the processor via the electrical contacts and determines whether to make the motherboard enter an overclocking operation mode according to a control command,
wherein the control chip transmits a control signal to the undefined pins of the processor via the second part of the electrical contacts, the processor responds to the control signal received from the undefined pins in an overclocking operation mode.

9 . The electronic device according to claim 8 , wherein the control chip detects load information of the processor and provides the control signal according to the load information to adjust an operating parameter of the processor in the overclocking operation mode.

10 . The electronic device according to claim 9 , wherein the control chip further controls an input voltage received by the processor according to the load information to make the processor maintain at a same voltage under different loads in the overclocking operation mode.

11 . The electronic device according to claim 8 , wherein the second part of the electrical contacts include a first group of the electrical contacts, and the first group of the electrical contacts are corresponding to a first group of the pins of the undefined pins.

12 . The electronic device according to claim 11 , wherein the control chip transmits a first control signal to the first group of the electrical contacts to make the processor respond to the first control signal to adjust one of a core ratio, a ring ratio, a memory ratio and a base clock frequency.

13 . The electronic device according to claim 12 , wherein the second part of the electrical contacts include a second group of the electrical contacts, and the second group of the electrical contacts are corresponding to a second group of the pins of the undefined pins.

14 . The electronic device according to claim 13 , wherein the control chip transmits a second control signal to the second group of the electrical contacts to make the processor respond to the second control signal to adjust one of the core ratio, the ring ratio, the memory ratio and the base clock frequency.
