2-2. Installing Memory
The DDR3 SO-DIMM sockets of ENDAT-GM451 support up to 8GB memory. The speed of
DDR3 memory can be DDR3-800 or DDR3-1066.
2-3. Shared VGA Memory
The ENDAT-GM451 built-in Intel® GMA4500MHD graphic engine with DVMT 5.0 up to
1GB of 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 designed to monitor and secure the system work
normally. WDT has an independent clock from the oscillator that can set time and
clear/refresh WDT counter function. When time is up, WDT send hardware RESET
signal to reset system.
Timeout Value Range
-1 to 255
-Second or Minute
