4-14 Upgrading Your System
DIMMs
The memory board contains sixteen DIMM sockets arranged in four banks (see
Figure 4-7). Each 168-pin socket can hold a single 72-bit DIMM module with
64MB, 128MB, or 256MB of memory. When all sixteen sockets are populated,
the memory board supports a maximum of 4GB of memory with 256MB
DIMMs. Your system supports a second memory board for a maximum system
memory of 8GB. DIMMs must be identical within a bank on each board.
Note
: DIMMs must be installed in a group (consisting of
four DIMMs) that is designated as one memory bank.
DIMMs must also be of the same type and capacity within a
bank.
The first bank of DIMMs should be installed in sockets P01, P02, P03 and P04
(see Figure 4-7). When you install additional DIMMs, you must start with bank
B and continue to bank D. When you remove DIMMs; you must start with the
highest populated bank 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.
