Problems solved by technology
[0004] Subsequently, Intel formulated corresponding Voltage Regulation Model (VRM) standards for its various processor products. Starting from the Prescott core microprocessor, the voltage regulation standard was changed to VRD (Voltage Regulation Down). The number of VID digits, voltage adjustment accuracy and voltage adjustment range in the standard are different. Therefore, each processor product with voltage adjustment standard must be used on the corresponding motherboard, because each motherboard only supports one voltage adjustment standard, so on this board it will not be possible to mix processor products that support different voltage regulation standards

The invention provides a method for converting a voltage identifier of a microprocessor and a computer system. The method comprises the following steps: firstly, a first voltage identifier belonging to a first voltage adjusting standard is received, and is corresponding to a first voltage value; secondly, the first voltage identifier is converted into a second voltage identifier belonging to a second voltage adjusting standard, and a second voltage value corresponding to the second voltage identifier is equal to the first voltage value. The method for converting the voltage identifier of the microprocessor actually causes that the processor products can be used for mainboards supporting different voltage adjusting standards through converting voltage identifiers among several voltage adjusting standards.
Description
technical field [0001] The invention relates to a method for converting voltage identification codes of microprocessors, and in particular to a method for converting voltage identification codes of microprocessors, so that the microprocessors can operate on mainboards with different voltage identification codes. Background technique [0002] Due to the advancement of technology, fluctuations in the core voltage (Vcore) of the microprocessor (or called the central processing unit) will affect the normal operation of the microprocessor. If the core voltage is too high, it will lead to increased heat generation, shortened life, or even burnt out of the microprocessor. Conversely, if the core voltage is too low, it may cause data corruption, crash, blue screen and other failures. Since the core voltage of the microprocessor is more and more integrated, the manufacturing process is more and more refined, and the core voltage of the microprocessor is getting larger and larger, the...
