Computer Memory Configurations
Adding more memory allows the computer to run larger, more complicated software and to run it faster.
The computer comes with 8 MB of memory hardwired to the main logic board. Additional memory can be
installed, to a maximum of 128 MB, using the two SIMM sockets on the main logic board.
When adding SIMMs, be sure to:
♦
Install a matching pair only.
♦
Install 32-bit SIMMs having an access time of 70 ns or less. Supported SIMM sizes: 4 MB, 8 MB,
16 MB, 32 MB or 64 MB.
♦
For improved performance, Starion Minitower PC computers are designed with interleaved memory.
This feature requires to populate both sockets. Ensure that the SIMM in each socket is the same type,
sizeand speed. Therefore, a 4-MB SIMM in socket J23 requires a 4 MB SIMM in socket J24.
