3.1.3.2. Installing the SDRAM Memory Module
The panel PC’s control board provides 2 x 168-pin DIMM
socket, able to support SDRAM memory from 32MB up to
512MB. To install the memory module, follow the
instructions below.
1. Find the 168 pin DIMM socket on the motherboard
2. There are two white eject levers at each end of the DIMM
socket. Push them outward until they separate from the
two vertical posts.
3. Holding the memory module with the notch on the upper
right corner, then insert the memory module into the
DIMM socket at 90° angle.
4. Push the two eject levers toward the vertical posts until
they click into place. The memory module is now
upright.
5. Retain the memory module to the SDRAM socket by
firmly fastening the SDRAM and the eject levers together
with nylon cable ties.
The system is able to auto detect the new memory size and
there is no need to change the system configuration after
installation.
Make sure that the memory module you are using can handle
the specified SDRAM MHz. Inadequate memory module will
make the computer unable to boot up.
PLEASE NOTE THAT ALTHOUGH THE MOTHERBOARD HAS TWO 168-PIN
DIMM SOCKETS, YET DUE TO CHIPSET LIMITATION, THE MAXIMUM
MEMORY CAPACITY SUPPORTED IS 512MB. IF TWO 512MB SDRAM
MODULES ARE INSERTED, ONLY 512MB SIZE CAN BE DETECTED.
