Installing Memory 2-7
2.02 SIMM CONFIGURATION & INSTALLATION
At least 1MB of system memory must be installed on the VIPer808 for proper operation.
Total System Memory can be configured as 1MB, 2MB, 3MB, 4MB, 8MB, 12MB, 16MB,
32MB, 48MB, 64MB or 128MB using 36-bit SIMM devices.
There are two SIMM (Single In-line Memory Module) sockets; these can accept the
following 36-bit modules:
•
256K x 36-bit = 1MB module,
•
512K x 36-bit = 2MB module,
•
1M x 36-bit = 4MB module,
•
2M x 36-bit = 8MB module,
•
4M x 36-bit = 16MB module, and
•
8M x 36-bit = 32MB module.
Note:
The VIPer808 board, will also support a total of 128MB of System Memory
when 64MB modules will be available.
Consult the table on the following page to see which SIMM configurations are available
on the VIPer808.
DRAM devices with page mode at 70ns maximum access time is recommended. Please
refer to Appendix E for a list of recommended devices.
When you are ready to install the SIMMs in the sockets, follow the steps outlined below.
•
With the board flat on the table, turn it so that the end of the board with the sockets is
near you.
•
Hold the module with the notch on the bottom right facing you, and insert the
connector into the socket at a 70° angle from the board (pin 1 on the module lines up
with pin 1 on the socket).
•
Snap the module forward to a vertical position in the socket. The module is fully
inserted when the retaining pegs snap into the holes at each end of the module.
