Disassembly and Reassembly 4-21
DIMMs
The memory board contains sixteen DIMM sockets arranged in four groups (see
Figure 4-16) of 4 way interleaved memory. Each 168-pin socket can hold a
single 72-bit DIMM module with 64MB, 128MB, 256MB, 512MB, or 1GB
(when available) of memory. When all sixteen sockets are populated, the
memory board supports a maximum of 16GB of memory with 1GB DIMMs.
DIMMs must be identical within a group on each board.
Note
: DIMMs must be installed in a group (consisting of
four DIMMs) that is designated as one memory group.
DIMMs must also be of the same type and capacity within a
group.
The first group of DIMMs should be installed in DIMM slots 1, 5, 9 and 13 (see
Figure 4-16, Group #1). When you install additional DIMMs, you must start
with Group #2 and continue to Group #4. When you remove DIMMs; you must
start with the highest populated group of DIMMs.
The following subsections describe the procedures for adding memory DIMMs
to your system.
!
WARNING
If the system was running, any processor and heat sink
installed is hot. To avoid the possibility of a burn while
configuring memory, let the components cool for 10 minutes
before continuing with the procedures described here.
Note:
DIMMs are grouped into four and must be installed in multiples of four.
