specify
whether
the
System
Partition
is
to

–
Memory
Settings
Select
this
choice
to
manually
enable
a
pair
of
memory
connectors.
If
a
memory
error
is
detected
during
POST
or
memory
configuration,
the
server
automatically
disables
the
failing
pair
of
memory
connectors
and
continues
operating
with
reduced
memory.
After
the
problem
is
corrected,
you
must
manually
enable
the
memory
connectors.
Use
the
arrow
keys
to
highlight
the
pair
of
memory
connectors
that
you
want
to
enable,
and
use
the
arrow
keys
to
select
Enable
.
You
can
select
any
of
the
following
memory
configurations:
-
The
flat
(default)
configuration
uses
memory
without
any
redundancy.
-
In
mirroring
mode,
memory
pairs
act
as
a
RAID
level
1
memory
array.
This
option
reduces
the
amount
of
memory
usable
by
the
system
by
half.
-
Sparing
mode
sets
aside
memory
to
dynamically
replace
a
section
of
failing
memory
during
system
operation.
This
mode
also
reduces
the
amount
of
memory
available
to
the
system.
The
mirroring
and
sparing
configuration
requires
that
the
memory
be
placed
in
multiple
memory
sockets.

CPU
Options
Select
this
choice
to
disable
the
microprocessor
cache
or
to
set
it
to
use
the
write-back
or
write-through
method.
Write-back
caching
generally
provides
better
system
performance.
Hyper-Threading
technology
enables
a
server
with
one
microprocessor
to
operate
as
if
it
were
two
microprocessors.
Utilizing
the
CPU
option
allows
better
system
performance,
and
will
appear
to
the
Operating
System
that
twice
the
number
of
microprocessors
are
present.
You
can
enable
the
Prefetch
Queue
option
from
the
CPU
options
menu.
The
Prefetch
Queue
option
along
with
64-bit
addressing,
in
EM64T,
can
boost
the
software
performance
of
the
server.
