DIGITAL Server 3220/3220R
Installing Additional Memory
The server has at least 64 MB of memory. Adding more memory enables the server
to run larger, more complicated software and run it more quickly. Registered
SDRAM DIMMS are available in 64 MB, 128 MB and 256 MB sizes to expand the
server memory up to 1GB with the 350 MHz processor.
Server memory is installed using the four DIMM sockets located on the processor
module, as shown in Figure 5-21. All four DIMM sockets accept single- or dual-sided
DIMMS.
When adding memory, make sure you reference the memory configuration table and
follow the memory expansion guidelines.
CAUTION:
DIMMs must be ordered separately. Only
install DIMMs supported by Digital Equipment
Corporation. DIGITAL does not support server
performance, product warranty, or service calls resulting
from installing non-qualified DIMMs.
