BIOS Setup
Thermal, Fans Speed and Voltages Monitor:
These items list current states of CPU and system (RT1 and RT2) temperature as well as fan
speed (CPU fan and chassis fan). It can not be changed by the user.
The following items list the voltage states of the system power. Just like Thermal & Fan
Monitor, it is unchangeable.
The hardware monitoring features for temperature, fans and voltages will occupy the
I/O address from 294H to 297H. If you have a network adapter, sound card or other
add-on cards that might use those I/O addresses, please adjust your add-on card I/O
address, to avoid the use of those addresses.
There are small differences in the chipset feature setup according to different motherboard
models, but this has no influence upon performance. Our default setup should be the best
one.
