3.3.16 SO-DIMM DDR2 Connector

TM
VIA CX700M chipset provides support to DDR2 memories. At this purpose, on board there is a
SO-DIMM DDR2 socket, type Tyco 1612773-4, a right angle, low profile socket, used for high
speed system memory applications.

3.3.17 Jumpers configuration

Some features of the board have to be set using the jumpers provided on the board:

JP1 set the voltage V
CN2.
Place jumper in position 1-2 to set V
Place jumper in position 2-3 to set V

JP2 controls if pin 2 of power connector CN15 can be used as an additional +5V
for legacy -12V .
DC
Place jumper in position 1-2 to use pin 2 of CN15 as an input rail for +5V
Place jumper in position 2-3 to use pin 2 of CN15 as an input rail for -12V

JP4 controls voltage level of I/O signals present on PC/104+ bus (this control, according to
PC/104+ specifications, is made though pins 2A, B6, B25, C19, D23 of PC104+ I/O connector).
Place jumper in position 1-2 for +5V
Place jumper in position 2-3 +3.3V
In case no expansion card is used with PC/104+bus, this jumper can be left empty
