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.
