Acer Altos R520 M2 has twelve DIMM slots. The DIMM slots are color-
coded and are labeled DIMM A1, DIMM A2, DIMM B1, DIMM B2, DIMM
C1, DIMM C2, DIMM D1, DIMM D2, DIMM E1, DIMM E2, DIMM F1, and
DIMM F2.
All twelve DIMM slots are shared by two processors. Each processor
controls six DIMM slots. The DIMM slots support three channel DDR3-
133 registered/unbuffered ECC memory modules. For processor 1, it
will be channels A, B, and C and for processor 2, it will be channels D, E,
and F. Each channel is divided into two sockets: Socket 1 and Socket 2.
Socket 1 slots are colored blue and comprised of DIMM slots A1, B1, C1,
D1, E1, and F1 and Socket 2 slots are colored black and comprised of
DIMM slots A2, B2, C2, D2, E2, and F2.
For all memory channel modes, populate the blue slots first, before
populating the black slots. If DIMM slots in Socket 1 are empty, the
DIMM slots in Socket 2 can not be used.
