Installing Additional Computer Memory
Adding more memory enables your computer to run larger, more complicated
software and run it more quickly.
Depending on the model you purchased, your computer comes with either 8 MB or 16
MB of Extended Data Out (EDO) memory. For those with 8 MB computers, memory
is installed as two 4 MB SIMMs in bank 0 (socket J11 and J12). For those with 16 MB
computers, memory is installed as two 8 MB SIMMs in bank 0 (socket J11 and J12).
When adding memory, you need to use 72-pin SIMMs (Figure 5-13).
For some models, you can increase this amount up to a maximum of 128 MB using
the four SIMM sockets on the main logic board. All other models, including all models
of the Celebris FX, can be increased up to 192 MB using the six SIMM sockets on the
main logic board.
All Venturis FX and Celebris FX computers support EDO memory. EDO memory, in
pairs of 4 MB, 8 MB, 16 MB, and 32 MB SIMMs, is faster than standard non-parity or
Fast Page memory. Contact your local Digital sales representative for ordering
information.
