Computer Memory Configurations
Adding more memory allows the server to run larger, more complicated software and run it quicker.
The amount of memory the server supports depends on the installed type of CPU module.
♦
When the i486 PCI Series CPU module is installed, the server will support up to 128 MB using
SIMM banks 0 through 3.
♦
When the Pentium 560/566 CPU module is installed, the server will support up to 256 MB using
SIMM banks 0 through 5. The Pentium 590 CPU module will support up to 512 MB using SIMM
banks 0 through 7.
CAUTION
If you plan on operating the server with 64 MB memory or more and the i486 PCI
Series CPU module have been installed, an additional 128 KB of secondary cache
should be installed. Failure to do so can cause server failure.
The server comes with at least 8 MB of memory.
When adding additional memory make sure to:
♦
Install 36-bit SIMMs having an access time of 70 ns or less.
♦
Fill two sockets at a time using the same SIMM size (4 MB, 8 MB, 16 MB, or 32 MB densities), type
and speed.
♦
Fill banks 0 and 1 before banks 2 and 3, banks 0 through 3 before banks 4 and 5, and banks 0 through
5 before banks 6 and 7.
