Important:
Dual-core
and
quad-core
microprocessors
are
not
interchangeable
and
cannot
be
used
in
the
same
server.
For
example,
if
the
server
has
a
dual-core
microprocessor,
you
cannot
install
a
quad-core
microprocessor
as
the
second
microprocessor.
Use
the
Configuration/Setup
Utility
program
to
determine
the
type
and
speed
of
the
microprocessor
that
is
currently
installed
in
the
server.
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:
2.
Enter
your
product
number
(machine
type
and
model
number)
or
select
Servers
and
Storage
from
the
Select
your
product
list.

to
download
firmware
updates.
v
To
order
additional
microprocessor
optional
devices,
contact
your
Lenovo
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
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.
