  • Patent number: 8604812
    Abstract: A voltage limiting test system used to test limit voltage values of a memory includes a voltage limiting test device and an assistant test device connected to the voltage limiting test device. The voltage limiting test device includes a button to adjust a voltage of the memory. The assistant test device includes a first timer, and first and second relays. The first relay is used to receive a state signal of the motherboard, to determine whether the first timer is powered according to the state signal. The second relay is used to receive the pulse signal output by the first timer when the first timer is powered, to trigger the button to adjust the voltage of the memory per a reference time. When the motherboard stops working, the voltage value of the memory is a limit voltage value of the memory.
