2-2. Installing Memory
The DDR3 SO-DIMM sockets of ENDAT-D2550 support up to 4GB memory. The speed of
DDR3 memory can be DDR3-800 or DDR3-1066.
2-3. Shared VGA Memory
The ENDAT-D2550 built-in Intel® GMA3600 graphic engine with DVMT 4.0 up system
memory. The amount of video memory on motherboard determines the number of colors
and the video graphic resolution.
2-4. Watch Dog Timer
Watch dog Timer (WDT) is a special design for system monitoring to secure the
system work normally. WDT has an independent clock from the oscillator and could
set time and clear/refresh WDT counter function. When time is up, WDT will send
hardware RESET signal to reset system.
