Software-Monitoring Tools
|
| < Day Day Up > |
|
Hardware-monitoring tools based on specialized chips or built into chipset components, and complemented with appropriate sensors, usually only provide measurement capabilities. To perform the control, output the measured results, and analyze them, you'll need special-purpose software. Relatively simple programs that provide this kind of service are built into the BIOS Setup program of most motherboards. Functionality, the number of measured parameters, and measurement precision usually depend on the chips used for this purpose, as well as on the BIOS code version. Fig. 6.9 shows the PC Health Status menu, included in the BIOS Setup program of most popular motherboards.

Although BIOS built-in functions often provide a wide range of capabilities, there are also specialized software applications that ensure control, analysis, and screen output of the diagnostic parameters. Such programs often use the built-in tools of popular operating systems (such as Windows). As a rule, motherboard manufacturers provide such software tools along with their products. The Winbond Hardware Doctor is a typical example of such a program. The screenshot in Fig. 6.10 illustrates its operation.
Figure 6.10: Typical screenshot of the Winbond Hardware Doctor application
The Winbond Hardware Doctor provides the capability of monitoring system parameters. The main parameters are as follows:
-
Voltage (supply voltage):
-
Vcore — CPU core voltage
-
Vtt — Additional CPU supply voltage
-
+3.3 V — Chipset, frequency generator, and PCI bus
-
+5 V — Chips of the motherboard, PCI bus, and ISA
-
+12 V — ISA bus
-
-5 V — ISA bus
-
5 Vsb — Supply voltage in hibernation mode
-
-
Fan speed (speed of fan rotation):
-
CPU fan
-
Power-supply fan
-
-
Temperature:
-
System1 — Temperature within the system (motherboard or case)
-
System2 — Temperature within the system (motherboard or case)
-
CPU temperature
-
The Winbond Hardware Doctor allows you to install the boundaries that serve as limiting values allowable for computer hardware — maximum (High Limit) and minimum (Low Limit) for each parameter being monitored (Fig. 6.11). For temperature control, only the maximum allowed values are important (Fig. 6.12). For fan speed, only the lower limits play a role (Fig. 6.13). If the value of the parameter being monitored goes beyond the valid range, the system displays a warning message accompanied by a sound (Fig. 6.14).

Note that the example application has one significant drawback: It is bound to a specific motherboard (or motherboard series) equipped with specific hardware-monitoring tools. Other programs provide more universal system-monitoring tools. The popular Motherboard Monitor (MBM) software is a good example of such a utility.
There are currently two significantly different versions of this tool: 4.xx and 5.xx. The first releases of version 5.xx contained several bugs that made the system unstable with some motherboards. Because of this, most PC users prefer version 4.xx. Fortunately, the most recent releases of the MBM software are free of these bugs. Table 6.7 lists the most popular chips supported by the MBM program. Note that this list grows with each new release of this popular program.

Tables 6.8–6.19 briefly outline the parameters of the motherboards from several leading manufacturers. These motherboards, according to the data provided by the MBM developer, are supported by MBM v. 5.3. These tables list the chips integrated into the motherboard architecture to ensure the capabilities of monitoring the most important parameters.

Most motherboards based on Via chipsets have built-in hardware-monitoring tools. Specialized software tools for hardware-monitoring are usually supplied with these motherboards. Shepherd is a good example of such a program (Figs. 6.19 and 6.20).
Figure 6.19: Operation of the Shepherd program
Figure 6.20: Temperature graph built using Shepherd
It is recommended that you start monitoring programs during system startup and never close them during computer operation. Such programs can issue a warning sound or even power down the computer if the temperature rises above the predefined limit. This feature is especially important for overclocked systems.
Note that such programs often run in background mode. Most of these applications do not consume many system resources. For example, on a computer equipped with a Pentium III 700 processor, the CPU workload is less than 1%, which means it corresponds approximately to the measurement error. This makes workload analysis unnecessary.
When evaluating the capabilities of hardware monitoring for subsystems and components, it is necessary to emphasize that contemporary hardware monitoring isn't limited to reading and analyzing the values of motherboard and CPU parameters. Today's high-performance video adapters are equipped with monitoring facilities that control the temperature of the video chipset, supply voltage, etc. The SmartDoctor program supplied with a range of Asus video adapters (Fig. 6.21) is a good example of such a software tool.
Figure 6.21: SmartDoctor at work
Note that in contemporary computers, hardware-monitoring functions control several parameters: two or three temperature values, three to nine voltage values, the rotation speed of two or three fans, and so on. Complemented by appropriate software and supported by add-on circuitry on the motherboard, they ensure protection of the computer from hardware instability or a malfunction, issuing a series of warning signals (and possibly powering down an overheated system). These functions provide the possibility of automatic overclocking as well. The range of such smart motherboards includes products from MSI Computer, Gigabyte Technology, and Soltek Computer.
Leading hardware manufacturers continue their efforts to improve hardware-monitoring facilities. Undoubtedly, new technologies that make use of their advanced functionality will further stimulate the growth of computer performance and extend their standard functional capabilities.
