4.2. Installing the SDRAM Memory Module
The OPEN (660) 120/140/150 II system control board
provides 1 x 168-pin DIMM socket, able to support
SDRAM memory from 32MB up to 256MB. To install the
memory module, follow the instructions below;
1. Detach and remove the rear cover.
2. Find the 168 pin DIMM socket on the motherboard
3. There are two white eject levers at each end of the
DIMM socket. Push them outward until they
separate from the two vertical posts.
4. Holding the memory module with the notch on the
upper right corner, then insert the memory module
into the DIMM socket at 90° angle.
5. Push the two eject levers toward the vertical posts
until they click into place. The memory module is
now upright.
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.
