Motherboards
|
|
|
|
|
|
------------
|
|
|
|
|
|
Most motherboards will work on the default MBProbe settings for voltage and
|
|
|
|
|
|
temperature sensors. The following lists some exceptions:
|
|
|
|
|
|
(Look for the sensor detected, then look for your board under that section)
|
|
|
|
|
|
If your board is not listed, try one of the combination of settings listed
|
|
|
|
|
|
under the appropriate sensor and please mail me about it. Thanks.

Motherboard Types
|
|
|
|
|
|
-----------------
|
|
|
|
|
|
Beginning with 1.30 there is an option to specify the motherboard type. This
|
|
|
|
|
|
will only be used for motherboards with certain non-standard features (or
|
|
|
|
|
|
bugs) which cannot be autodetected (or where autodetection may lock-up other
|
|
|
|
|
|
motherboards).
|
|
|
|
|
|
|
|
|
|
|
|
The following motherboards may be specified:
|
|
|
|
|
|
1=Reserved
|
|
|
|
|
|
2=FIC SD-11
|
|
|
|
|
|
Newer BIOSes disabled the hardware monitoring of the VT82C686A. This
|
|
|
|
|
|
option re-enables it.
|
|
|
|
|
|
3=Super I/O at 2eh
|
|
|
|
|
|
This enables the scanning for the SMSC 47xxxx chips which provide fan
|
|
|
|
|
|
speed readings. Boards include Intel D815EEA, VC820, OR840 and possibly
|
|
|
|
|
|
other i8x0-based Intel boards as well.
|
|
|
|
|
|
This also scans for the NS PC87366 which includes hardware monitoring.
|
|
|
|
|
|
Boards include Chaintech 6WIM.
|
|
|
|
|
|
4=Super I/O at 4eh
|
|
|
|
|
|
This enables the scanning for the SMSC 47xxxx chips which provide fan
|
|
|
|
|
|
speed readings and the NS PC87366 which includes hardware monitoring.
|
|
|
|
|
|
|
|
|
|
|
|
If you have any of these motherboards, enable support for it by changing the
|
|
|
|
|
|
following registry key:
|
|
|
|
|
|
|
|
|
|
|
|
HKEY_LOCAL_MACHINE\Software\Jonathan Teh\MBProbe\1.30\MotherboardType=n
|
|
|
|
|
|
|
|
|
|
|
|
where n is the number of the motherboard given above.
|
|
|
|
|
|
|
|
|
|
|
|
1. Run regedit.exe
|
|
|
|
|
|
2. Go to "HKEY_LOCAL_MACHINE\Software\Jonathan Teh\MBProbe\1.30"
|
|
|
|
|
|
3. Select "Edit" from the menu, then "New", then "DWORD Value".
|
|
|
|
|
|
4. Type "MotherboardType" (without the quotes).
|
|
|
|
|
|
5. Double-click on "MotherboardType" and enter the motherboard type.
|
|
|
|
|
|
6. Close regedit.
|
|
|
|
|
|
7. Restart MBProbe.
|
|
|
|
|
|
|
|
|
|
|
|
This may become part of the GUI front-end in future versions.

|
|

|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
If your CPU is not listed, check the temperature in the BIOS and compare it
|
|
|
|
|
|
with the temperature reported by MBProbe. Take the difference as the offset
|
|
|
|
|
|
and submit a report to me. Thanks.

Notes
|
|
|
|
|
|
1 External temperature measurement requires thermistors or diodes.
|
|
|
|
|
|
2 External temperature measurement requires thermistors.
|
|
|
|
|
|
3 External temperature measurement requires diodes.
|
|
|
|
|
|
4 Voltage input for Vccp2 can also function as -12V.
|
|
|
|
|
|
5 Vccp2 reading is actually the sensor chip's Vcc.
|
|
|
|
|
|
6 When temperature input 3 is enabled, Vccp2 and +2.5V are disabled
|
|
|
|
|
|
as they are the same pins.
|
|
|
|
|
|
7 At least one board (Tekram P6B40-A4X) uses Vccp2 to connect an external
|
|
|
|
|
|
thermistor so MBProbe has a custom sensor setting for that.
|
|
|
|
|
|
8 These chips can monitor 2 voltages for brownouts but there is no way of
|
|
|
|
|
|
reading the actual voltage values.
|
|
|
|
|
|
9 MBProbe only displays 9 of the 11 voltages; Vdd and AVdd are omitted.

In the temperature selection:
|
|
|
|
|
|
:0 refers to temperature of the chip itself (except MAX1618)
|
|
|
|
|
|
:n refers to the temperature of the nth external thermal diode.

|
|
|
on it.
