Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
must
update
the
basic
input/output
system
(BIOS)
code
in
the
server.
To

Microprocessor
installation
order
The
following
notes
describe
the
order
in
which
to
populate
the
microprocessor
connectors:
v
For
most
configurations,
populate
the
microprocessor
connectors
in
numeric
order,
starting
with
connector
1.
v
If
you
plan
to
create
a
two-node
configuration
using
four
dual-core
microprocessors,
you
can
populate
the
microprocessor
connectors
to
improve
performance.
The
following
notes
describe
information
that
you
must
consider
when
configuring
the
servers
to
use
the
configuration:
–
You
must
create
this
configuration
using
one
System
x3950
(xSeries
460)
server
as
the
primary
node
and
one
System
x3950
E
(xSeries
460
MXE)
server
as
the
secondary
node.
–
Only
the
configuration
described
in
these
instructions
is
supported
to
improve
performance.
–
See
this
section
for
instructions
on
installing
a
microprocessor.
–
See
the
Problem
Determination
and
Service
Guide
for
instructions
on
removing
a
microprocessor.
–
Use
this
configuration
only
with
supported
Windows
2003
operating
systems.
To
configure
a
two-node
configuration
to
use
the
four
dual-core
microprocessor
configuration,
complete
the
following
steps.
Important:
The
grease
on
the
heat
sink
and
microprocessor
will
remain
effective
when
you
move
a
microprocessor
from
one
connector
to
another
connector,
if
you
observe
the
following
precautions:
v
Carefully
handle
the
heat
sink
and
microprocessor
when
removing
or
installing
these
components.
Do
not
touch
the
grease
or
otherwise
allow
it
to
become
contaminated.
v
Because
the
microprocessor
and
heat
sink
are
a
matched
set,
transfer
the
microprocessor
and
heat
sink
from
one
connector
to
another
connector
one
microprocessor
and
heat
sink
at
a
time.
(This
will
ensure
that
the
grease
remains
evenly
distributed
between
each
heat
sink
and
microprocessor.)
1.
Remove
the
microprocessor
and
heat
sink
installed
in
connector
2
of
the
primary
node
and
install
it
in
connector
1
of
the
secondary
node.
2.
Install
a
microprocessor
and
heat
sink
option
in
connector
3
of
the
primary
node
and
install
a
VRM
in
VRM
connector
3.
3.
Install
a
microprocessor
and
heat
sink
option
in
connector
3
of
the
secondary
node
and
install
a
VRM
in
VRM
connector
3.
Note:
To
install
additional
microprocessors
in
this
configuration,
populate
connector
2;
then,
connector
4
in
the
primary
node.
To
install
additional
microprocessors,
populate
connector
2;
then,
connector
