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.
