Refer to Chapter 1, "Beyond Quick Setup," for information on removing and replacing

Installing Additional Computer Memory

Your computer supports 168-pin DIMM memory modules utilizing Synchronous
Dynamic Random Access Memory (SDRAM) technology. SDRAMs operate at
speeds of 66 MHz (or greater) over a local memory bus, which is much faster than
SIMMs using ECC or EDO memory.
Depending on the model you ordered, your computer came with either 16 MB, 32
MB, or 64 MB of computer memory. Adding more memory enables your computer to
run larger, more complicated software and run it more quickly. DIMMs are available
in 16 MB, 32 MB, 64 MB, and 128 MB memory module sizes to expand your
computer memory up to 384 MB. Use only DIGITAL qualified memory modules for
optimal operation.
Contact your local DIGITAL sales representative for ordering information.
