The
following
notes
apply
when
the

operates
in
non-mirroring
mode
(normal
mode):
–
DIMMs
must
be
installed
in
matched
pairs.
If
you
install
a
second
pair
of
DIMMs
in
DIMM
connector
7
and
DIMM
connector
10,
they
do
not
have
to
be
the
same
size,
speed,
type,
and
technology
as
the
DIMMs
in
DIMM
connector
1
and
DIMM
connector
4.
However,
the
size,
speed,
type,
and
technology
of
the
DIMMs
that
you
install
in
DIMM
connector
7
and
DIMM
connector
10
must
match
each
other.
