Installing memory modules Adding memory to your server is an easy way to make programs run faster. You can increase the amount of memory in your server by installing options called memory modules. Each module contains one industry-standard, dual in-line memory module (DIMM). Your server uses a noninterleaved memory configuration. Memory considerations: v The server comes with a DIMM installed on the system board in DIMM connector 1. v When installing additional memory modules, install the second memory module in DIMM connector 2, and the third in DIMM connector 3. (See the illustration in this section for memory connector locations.) v The xSeries 200 server supports 64 MB, 128 MB, 256 MB, and 512 MB DIMMs. Your server supports a minimum of 64 MB and a maximum of 1.5 GB of system memory. See the ServerProven list at http://www.ibm.com/pc/compat for a list of memory modules for use with your server. v Installing or removing DIMMs changes the configuration information in the server. Therefore, after installing or removing a DIMM, you must change and save the new configuration information by using the Configuration/Setup Utility program. When you restart the server, the system displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings. See Chapter 4, "Configuring the server," on page 33 for more information. v The illustrations in this document might differ slightly from your hardware. Chapter 5. Installing options 61

Installing
memory
modules
Adding
memory
to
your
server
is
an
easy
way
to
make
programs
run
faster.
You
can
increase
the
amount
of
memory
in
your
server
by
installing
options
called
memory
modules.
Each
module
contains
one
industry-standard,
dual
in-line
memory
module
(DIMM).
Your
server
uses
a
noninterleaved
memory
configuration.
Memory
considerations:
v
The
server
comes
with
a
DIMM
installed
on
the
system
board
in
DIMM
connector
1.
v
When
installing
additional
memory
modules,
install
the
second
memory
module
in
DIMM
connector
2,
and
the
third
in
DIMM
connector
3.
(See
the
illustration
in
this
section
for
memory
connector
locations.)
v
The
xSeries
200
server
supports
64
MB,
128
MB,
256
MB,
and
512
MB
DIMMs.
Your
server
supports
a
minimum
of
64
MB
and
a
maximum
of
1.5
GB
of
system
memory.
See
the
ServerProven
list
at
for
a
list
of
memory
modules
for
use
with
your
server.
v
Installing
or
removing
DIMMs
changes
the
configuration
information
in
the
server.
Therefore,
after
installing
or
removing
a
DIMM,
you
must
change
and
save
the
new
configuration
information
by
using
the
Configuration/Setup
Utility
program.
When
you
restart
the
server,
the
system
displays
a
message
indicating
that
the
memory
configuration
has
changed.
Start
the
Configuration/Setup
Utility
program
and
select
Save
Settings
.

Chapter
4,
“Configuring
the
server,”
on
page
33
for
