v
The
server
supports
up
to
two
microprocessors.
If
the
server
comes
with
one
microprocessor,
you
can
install
a
second
microprocessor.
v
Both
microprocessors
must
have
the
same
cache
size
and
type,
front-side
bus
frequency,
and
clock
speed.
Microprocessor
internal
and
external
clock
frequencies
must
be
identical.
v
When
you
install
a
microprocessor
in
microprocessor
connector
2,
you
must
also
install
the
voltage
regulator
module
(VRM),
which
comes
with
the
microprocessor,
in
the
VRM
connector.
v
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
must
update
the
basic
input/output
system
(BIOS)
code
for
the
server.
To
download
the
most
current
level
of
BIOS
code
and
many
other
code
updates
for
your
server,
complete
the
following
steps:
1.
Go
to
http://www.ibm.com/systems/support/.
2.
Under
Product
support
,
click
System
x
.
3.
Under
Popular
links
,
click
Software
and
device
drivers
.
4.
Click
System
x3650
to
display
the
matrix
of
downloadable
files
for
the
server.
v
(Optional)
Obtain
an
SMP-capable
operating
system.
For
a
list
of
supported
operating
systems
and
optional
devices,
see
http://www.ibm.com/servers/eserver/
serverproven/compat/us/.
v
To
order
additional
microprocessor
optional
devices,
contact
your
IBM
marketing
representative
or
authorized
reseller.
v
The
microprocessor
speeds
are
automatically
set
for
this
server;
therefore,
you
do
not
have
to
set
any
microprocessor
frequency-selection
jumpers
or
switches.
v
If
you
have
to
replace
a
microprocessor,
call
for
service.
v
If
the
thermal-grease
protective
cover
(for
example,
a
plastic
cap
or
tape
liner)
is
removed
from
the
heat
sink,
do
not
touch
the
thermal
grease
on
the
bottom
of
the
heat
sink
or
set
down
the
heat
sink.
v
Do
not
remove
the
first
microprocessor
from
the
system
board
to
install
the
second
microprocessor.
See
“System-board
optional-device
connectors”
on
page
17
for
the
location
of
the
microprocessor
connectors
and
the
VRM
connector.
The
following
illustration
shows
how
to
install
the
second
microprocessor
on
the
system
board.
