Installing DRAM (SIMMs)
The PCM-5894/5892 provides two 72-pin SIMM (Single In-line
Memory Module) sockets. The SIMM supports either Fast Page
Mode (FPM) or Extended Data Output (EDO) DRAM with a
speed of at least 70 ns. Depending on the combinations of the
modules you use, you can install from 4 MB to 128 MB of RAM.
Installing SIMMs
NOTE 1: Pentium or compatible processors adopt 64 bit data
bus. Since 72-pin SIMM can only provide 32 bit data
bus width, two SIMM modules are required as one
memory bank, and both SIMMs must be the same size
and type.
1. Ensure that all power sources are disconnected.
2. Slip the memory module into the socket at a 45 degree angle.
3. Push the module toward the vertical posts at both ends of the
socket until the module is upright and the retaining clips at
both ends of the module click into place. When positioned
correctly, the pins on top of the vertical posts should corre-
spond to the circular holes on the ends of the module.
4. Repeat steps 2 and 3 for each module you install.
NOTE 2: Do not insert any SIMM module that contains more
than 24 memory chips. SIMMs contain more than 24
chips exceed the driving capability of new generation
chipsets.
