PC Health Status
We will take a look at this area first because it allows viewing of
various sensors on the motherboard. It is a good idea to keep an eye on
these readings whilst making adjustments to other settings and in
particular when overclocking the CPU or RAM.
Be aware that the readings shown are not guaranteed to be fully
accurate. Precise readings can only be made with external instruments
such as temperature probes and multi-meters. The screen shown below will be similar on most systems, regardless of wether it is 32-bit or 64-bit.
Fan Speeds
The speed, in RPM, will be shown for all fans which are hooked-up to
the fan connectors on the motherboard. I this case none are so all
speeds are zero. The CPU is watercooled, hence no fan. Note that the
smart fan feature has been disabled because of this. When enabled it
will allow the fan speed to automatically change according to
temperature.
CPU Voltage
The current voltage reading is shown here. Note that the voltage
setting is not displayed, but the actual current voltage according to
the sensor. The voltage will fluctuate on an AMD64 system, see more on
this later.
AGP Voltage
AGP refers to the graphics card port. It is very important for the
AGP voltage to be set to match the voltage requirement of the graphics
card used. Generally, it is not advised to run this at higher voltages.
Chipset Voltage
In this case the chipset is the nForce 3 Ultra chip which is located
on the motherboard underneath a heatsink cooler. If running at a higher
voltage, improved cooling is usually recommended.
+5V
The power supply has a 5 volt line. This reading shows the actual
voltage on that line. In this case it is well within tolerance.
DIMM Voltage
The DIMM's are the dual inline memory modules otherwise known as
RAM. Exact voltage requirements will vary according to the modules used
and whether the memory speed is increased above stock.
Battery Voltage
There is a small disc shaped battery on the motherboard which
maintains power to the CMOS memory, so that BIOS settings are not lost
when the mains power is disconnected. This reading allows easy
verification of the battery's charge.
5V Standby
The 5V standby
voltage is an always-on power line this maintains power to certain
devices whilst the system is in sleep mode.
ACPI Shutdown Temperature
The ACPI shutdown temperature can be set or disabled as needed. The
system will automatically shutdown at the specified temperature to
avoid damage from overheating.
