<h2>What is it?</h2>
|
|
|
|
|
|
MBProbe is a program which monitors voltages, temperatures and fan speeds
|
|
|
|
|
|
using monitoring chip(s) present on many modern motherboards. Its features
|
|
|
|
|
|

<h2>Usage</h2>
|
|
|
|
|
|
Simply start MBProbe from the Windows start menu. The first time it starts,
|
|
|
|
|
|
it attempts to automatically configure the CPU voltage and temperature sensors
|
|
|
|
|
|
settings. All voltage warnings are enabled as well as motherboard temperature
|
|
|
|
|
|
warning. Warnings for CPU and power supply temperature as well as for each
|
|
|
|
|
|
fan will be enabled if the relevant sensors are present.<br>
|
|
|
|
|
|
<br>
|
|
|
|
|
|
If there is a problem with accessing the SMBus on your system, start MBProbe
|
|
|
|
|
|
with the "-nosmbus" parameter from the command-line:<br>
|
|
|
|
|
|
<pre>MBProbe -nosmbus</pre>
|
|
|
|
|
|
The event log is stored in the file "MBProbeEventLog.txt" and it logs warning
|
|
|
|
|
|
events and critical events. The history log is stored in the file "MBProbeHistoryLog.txt"
|
|
|
|
|
|
and it stores spot readings taken at regular intervals.
|
|
|
|
|
|
|
|
|
|
|
|
<h2>Status icon</h2>
|
|
|
|
|
|
The status icon shows the current temperature of the selected device. This
|
|
|
|
|
|
has a range from -199-199 with the display saturating at either end i.e.
|
|
|
|
|
|
if the reading is greater than 199, it will display 199. If you chose to
|
|
|
|
|
|
swap temperature readings, it will cycle in the colour sequence of green,
|
|
|
|
|
|
cyan, white and yellow for temperature sensors 1 to 4 respectively. Negative
|
|
|
|
|
|
temperatures are displayed with a blue background.<br>
|
|
|
|
|
|
<br>
|
|
|
|
|
|
Left-click to display the main window or right-click to display the context
|
|
|
|
|
|
menu. Left-clicking also clears the horizontal lines which are displayed
|
|
|
|
|
|
after a warning event has occurred.<br>
|
|
|
|
|
|
<br>
|
|
|
|
|
|
The tooltip displays motherboard temperature, CPU temperature and CPU fan
|
|
|
|
|
|
speed.
|
|
|
|
|
|
|
|
|
|
|
|
<h2>Main window<br>
|
|
|
|
|
|
</h2>
|
|
|
|
|
|
The main window shows all the readings obtained from the monitoring chip(s).
|
|
|
|
|
|
The chips are read every 5 seconds.<br>
|
|
|
|
|
|
<br>
|
|
|
|
|
|
The check box on the left of each item enables/disables the warning for each
|
|
|
|
|
|
reading. The light on the right shows the status of the reading:<br>
|
|
|
|
|
|
<blockquote>Grey : Warning disabled<br>
|
|
|
|
|
|
Green: OK<br>
|
|
|
|
|
|
Red : Warning threshold exceeded- action needed<br></blockquote>
|
|
|
|
|
|
<br>
|
|
|
|
|
|
The main window automatically pops-up when a warning threshold has been exceeded.
|
|
|
|
|
|
|
|
|
|
|
|
<h2>Properties</h2>
|
|
|
|
|
|
The properties dialog consists of 6 tabs:
|
|
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
|
<li>Voltage</li>
|
|
|
|
|
|
</ul>
|
|
|
|
|
|
<blockquote>This allows you to set the nominal voltage for your CPU core
|
|
|
|
|
|
and 3.3V I/O. The warning threshold setting limits the deviation of all
|
|
|
|
|
|
voltage readings to within that percentage. E.g. a nominal voltage of 2.00V
|
|
|
|
|
|
and a 10% warning threshold triggers a warning when the voltage drops below
|
|
|
|
|
|
1.90V or rises above 2.10V. The critical threshold works similarly but triggers
|
|
|
|
|
|
a critical event.<br>
|
|
|
|
|
|
</blockquote>
|
|
|
|
|
|
<ul>
|
|
|
|
|
|
<li>Temperature</li>
|
|
|
|
|
|
</ul>
|
|
|
|
|
|
<blockquote>The warning limit sets the temperature which, when exceeded,
|
|
|
|
|
|
will trigger a warning. The critical limit, when exceeded, will trigger
|
|
|
|
|
|
a critical event.<br>
|
|
|
|
|
|
The temperature offset is added to the raw temperature reading from the sensor.
|
|
|
|
|
|
This is generally only required for Socket-7 CPUs.<br>
|
|
|
|
|
|
The sensor input allows you to set the temperature sensor corresponding to
|
|
|
|
|
|
each reading. This is to allow for the different sensors adopted by various
|
|
|
|
|
|
motherboard manufacturers. Note that only sensors detected on your system
|
|
|
|
|
|
are displayed.<br>
|
|
|
|
|
|
The CPU thermal diode option is only enabled on certain chips. The W83782D/3S
|
|
|
|
|
|
have temperature inputs which can be connected to either thermistors or
|
|
|
|
|
|
thermal diodes. Check the correct sensor for those connected to a thermal
|
|
|
|
|
|
diode.<br>
|
|
|
|
|
|
</blockquote>
|
|
|
|
|
|
<ul>
|
|
|
|
|
|
<li>Fan</li>
|
|
|
|
|
|
</ul>
|
|
|
|
|
|
<blockquote>This allows you to set the nominal fan speed for each fan. Typical
|
|
|
|
|
|
values are 2200, 4400 and 8800RPM. Check your fan manufacturer for the correct
|
|
|
|
|
|
value, otherwise just take the current reading as the nominal value. The
|
|
|
|
|
|
'warning below' option sets the threshold at which a warning will be triggered.
|
|
|
|
|
|
E.g. a 4400RPM nominal speed and 70% threshold will trigger a warning when
|
|
|
|
|
|
the fan speed drops below 3080RPM. A fan dropping below 70% of its nominal
|
|
|
|
|
|
speed is generally accepted as a 'blocked' fan.<br>
|
|
|
|
|
|
The divisor option is due to the way fan speeds are calculated from the values
|
|
|
|
|
|
given by the monitoring chip. If you have a fan connected to an input and
|
|
|
|
|
|
it shows 0RPM, try selecting a higher fan divisor.<br>
|
|
|
|
|
|
The labels option allows you to specify the labels for each fan input. This
|
|
|
|
|
|
is due to the fact that labelling is non-standard among different motherboard
|
|
|
|
|
|
manufacturers.<br>

logging the warning in the event log. <br>

A critical event occurs when any temperature exceeds the value specified
