A memory controlling method adapted for driving a memory within a computer system is disclosed. When the computer system is booted, the memory is driven and tested via the BIOS. The memory controlling method performs tests on multiple controlling signals of the memory. The memory controlling method includes steps of: detecting an active window of each controlling signal; determining whether the active windows is larger than a predetermined window; performing a parameter adjustment on the controlling signals if one of the active windows is smaller than the predetermined window; performing a phase range test between two of the control signals if the active windows are larger than the predetermined window; performing a phase adjustment on the active windows of the controlling signals if the controlling signals fails in the phase range test; and driving the memory according to the adjusted controlling signals.

Memory controlling method

A computer device and frequency adjusting method for central processing unit are provided. The computer device including a CPU, a voltage regulator module, a clock generator, a power-on module, a chip set and an embedded controller. The power-on module activates the voltage regulator module, the clock generator and the CPU respectively. The voltage regulator module provides the operating voltage of the CPU. The clock generator provides the operating clock of the CPU. Before the CPU is activated, the embedded controller adjusts the operating clock and the operating voltage provided from the clock generator and the voltage regulator module the CPU, the CPU performs overclocking/downclocking directly by using the adjusted operating clock and the adjusted operating voltage after the CPU is activated.

Computer device and frequency adjusting method for central processing unit

A controllable power supply device with a step-up function including a constant voltage generator, a programmable voltage generator, a first switch and a linear regulator is provided. The constant voltage generator is used to provide an initial voltage. The programmable voltage generator is used to receive the initial voltage and adjust the received initial voltage to boost the initial voltage to a power supply voltage. The first connecting terminal of the first switch is used to receive the initial voltage, the second connecting terminal of the first switch is used to receive the power supply voltage, and the third connecting terminal of the first switch is coupled to one of the first connecting terminal and the second connecting terminal. Therefore, the voltage from the third connecting terminal of the first switch is stabilized and is outputted as the output voltage of the controllable power supply device by the linear regulator.
