5.3. Installing the SDRAM Memory Module
The APOLLO 120/150 III system control board provides 1 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.
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.
