MSK412 Style Memory
The minimum memory capacity per domain utilizing the MSK412 memory board is 384
megabytes. Memory capacity may be expanded to 4608 megabytes per domain in
increments of 384 megabytes by adding up to two additional MSK412 memory boards and
by adding six chip sets (twelve DIMMs) per memory board.
Figure 3–3 depicts the board layout showing the location of the major components of the
MSK412 memory board. Since memory increments are in bank and segment order, further
defined by the Server ASIC, the basic 384 MB board will have four DIMMS (00, 10, 20, 30)
installed. A DIMM is comprised of sixteen 16M X4 BIT DRAMS and provides for 96 MB of
memory. Memory capacity for the board is expanded to 1536 megabytes by adding twelve
additional DIMMS: (01,11, 21, 31); (02,12, 22, 32); and (03, 13, 23, 33).
