Abstract

A CPU escalating adapter with multivoltage and multiple frequency selection which is adapted for an escalated CPU is disclosed. The CPU escalating adapter comprises a circuit board, a power connection, a voltage regulator, a stabilivolt integrated circuit, a programmable array logic (PAL) and a toggle switch member. The cooperation of the toggle switch member and the voltage regulator forms a multiple voltage switching and a plurality of switches of the toggle switch member forms a selecting range between 2 and 5.5 of the frequency multiplication factor of the CPU.

Claims

1. A CPU escalating adapter with multivoltage and multiple frequency selection comprising:

a circuit board defining a plurality of recesses for receiving a CPU and having a plurality of pins extending downwardly therefrom to be inserted into a CPU socket of a computer host, said plurality of pins including a plurality of bus frequency pins for determining a frequency multiplication factor for the CPU;

a power connection disposed at one side of the circuit board for supplying power to the CPU escalating adapter;

a voltage regulator disposed on the circuit board for providing a supply voltage to the CPU;

toggle switch member disposed on the circuit board and connected to the voltage regulator and the plurality of bus frequency pins for setting the supply voltage and the frequency multiplication factor for the CPU; and

a stabilivolt integrated circuit connected to the voltage regulator, the stabilivolt integrated circuit having a reference voltage input end for receiving a reference input voltage, the reference voltage input end being connected to the toggle switch member whereby the reference input voltage as well as the supply voltage to the CPU is modified by setting the toggle switch member.

2. A CPU escalating adapter with multivoltage and multiple frequency selection as claimed in claim 1, wherein the reference voltage input end of said stabilivolt integrated circuit is connected to the toggle switch member via a divider resistor for changing a negative feedback of the divider resistor by switching the toggle switch member.

3. A CPU escalating adapter with multivoltage and multiple frequency selection as claimed in claim 1, wherein said toggle switch member has a plurality of switches connected with the plurality of bus frequency pins for providing a function of selecting frequency multiplication factors.

4. A CPU escalating adapter with multivoltage and multiple frequency selection as claimed in claim 1, further includes a programmable array logic (PAL) for converting a part of control signals of the CPU.
