3.3.1 Overview
The motherboard comes with two 204-pin Double Data Rate 3 (DDR3) Small Outline
Dual Inline Memory Modules (SO-DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR SO-DIMM but has a
204-pin footprint compared to the 204-pin DDR2 DIMM. DDR3 DIMMs are notched
differently to prevent installation on a DDR2 DIMM socket. The following figure illustrates
the location of the sockets:
24 Hardware Installation
MANO861 Mini ITX Board
Important
IF you installed four 1GB memory modules, the system may detect
less than 3GB of total memory because of address space allocation
for other critical functions. This limitation applies to Windows XP
32-bit version operating system since it does not support PAE
(Physical Address Extension) mode.
IF you install Windows XP 32-bit version operating system, we
recommend that you install less than 3GB of total memory.
For dual channel configuration, the total size of memory module(s)
installed per channel must be the same for better performance
(DIMMA1=DIMMB1).
Always install SO-DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.
Due to CPU limitation, SO-DIMM modules with 128Mb memory chips
or double-sided x16 memory chips are not supported in this
motherboard.

About Watchdog Timer
Software stability is major issue in most application. Some embedded systems are not
watched by human for 24 hours. It is usually too slow to wait for someone to reboot when
computer hangs. The systems need to be able to reset automatically when things go wrong.
The watchdog timer gives us solution.
The watchdog timer is a counter that triggers a system reset when it counts down to zero from
a preset value. The software starts counter with an initial value and must reset it periodically. If
the counter ever reaches zero which means the software has crashed, the system will reboot.
The integrated watchdog timer can be set up by programming. There are 1~255 levels
available.
How to Use Watchdog Timer
Assume that program A needs to keep running in a system. The value of watchdog timer must
be set bigger than the running time of program A. Then, after the running time of program A is
finished, either to disable or to reset watchdog timer.
When program A has problems that cause system shut down, the system can be rebooted by
watchdog timer when the value of watchdog timer has counted down to 0.
