  • Patent number: 11362464
    Abstract: A contact arrangement, including multiple contacts, is provided. The contacts are staggered. Some of the contacts form at least one contact group. The at least one contact group includes a pair of first contacts and eight second contacts. The pair of first contacts is a pair of differential signal contacts. The second contacts are arranged around the pair of first contacts. Two of the second contacts are arranged along a straight line perpendicular to a connecting line of the pair of first contacts. The position distribution and electrical properties of the other six of the second contacts are symmetrical to each other relative to the straight line.

  • Patent number: 8335941
    Abstract: A method for reducing power consumption of a computer system in a working state is provided. The computer system comprises a processor, a memory and a chipset, and the processor is connected with the chipset through a processor bus. The method comprises classifying the power saving level of the computer system into a predetermined number of power saving modes, checking at least one power saving mode transition condition to determine whether to automatically raise the power saving mode of the computer system, and raising the power saving mode of the computer system by lowering a first voltage supply level of the chipset and a second voltage supply level of the memory and decreasing a first working frequency of the processor bus and a second working frequency of the memory. The power consumption of the computer system is further reduced in comparison with a normal working state when the power saving mode of the computer system is further raised.

  • Patent number: 7689847
    Abstract: A method for dynamically increasing the data processing capability of a computer system is provided. The computer system comprises a processor, a memory and a chipset. The data processing capability of the computer system is classified into a predetermined number of performance enhancing modes. At least one performance enhancing mode transition condition is checked to determine whether to automatically raise the performance enhancing mode of the computer system. The processor is suspended from using the processor bus during the transition of the performance enhancing mode of the computer system. The performance enhancing mode of the computer system is raised by increasing a first working frequency of the processor, a second working frequency of the processor bus and a third working frequency of the memory. The data processing rate of the computer system is further increased when the performance enhancing mode of the computer system is further raised.
