How does CPU Warning Temperature set?

Filed under: computer knowledge — admin @ 7:04 pm

Q: my motherboard is abit BE7-G (i845PE chipset), there are two options on the CPU temperature of the BIOS, one is “CPU Warning Temperature” option, another is “CPU Shutdown Temperature”, the two options represent what meaning?

A: the two options a CPU alert (Warning Temperature), the temperature is another limit temperature (Thermal Trip), which refers to the core temperature of CPU, but the two represents the significance of different temperature. Warning temperature is to ensure the stable operation of CPU temperature; limit temperature is also called the highest core temperature (Maximum Die Temperature) or shutdown temperature, it is to prevent the burning of CPU temperature.
The warning temperature and the limiting temperature are determined by the manufacturing process, package form and packaging materials of CPU. To prevent the user from setting himself up, the manufacturer (such as Intel) writes the two temperatures into the ROM in the CPU internal TCC (Thermal, Control, Circuit, temperature control circuitry), and the user cannot modify them. Now a lot of motherboard BIOS can also set the alarm temperature and shutdown temperature, but optional numerical conservative, such as warning the maximum temperature of 70 degrees Celsius, the shutdown temperature is 85 DEG C, which is far lower than the set value in TCC.
