Installing DRAM (DIMMs)
System Memory
The left edge of the SBC-770 contains three sockets for 168-pin
dual inline memory module (DIMM). The socket uses 3.3 V
unbuffered synchronous DRAM (SDRAM). DIMM is available in
capacities of 16, 32, 64, or 128 MB. The socket can be filled in the
DIMM of any size, giving your SBC-770 single board computer
between 16 and 128 MB of memory.
Supplementary information about DIMM
Your SBC-770 can accept both regular and PC-100 SDRAM DIMM
Module(with or without parity). However, if the Pentium II 350MHz
or up CPU is used, The SBC-770 can only accept PC-100 SDRAM
DIMM Module.
Single-sided modules are typically 16 or 64 MB; double-sided
modules are usually 32 or 128 MB.
Memory Installation Procedures
To install DIMM, first make sure the two handles of the DIMM
socket are in the "open" position. i.e. The handles remain outward.
Slowly slide the DIMM module along the plastic guides on both
ends of the socket. Then press the DIMM module right down into
the socket, until you hear a click. This is when the two handles
have automatically locked the memory module into the correct
position of the DIMM socket. (See Figure below) To take away the
memory module, just push both handles outward, and the memory
module will be ejected by the mechanism in the socket.
