DIMM UPGRADE
Memory upgrades are installed into memory module sockets
on the system board. The system board provides four
sockets for memory modules and supports up to 512 MB of
high-speed memory. The system supports SDRAM modules
in 16-, 32-, 64-, and 128-MB 64-bit, non-parity memory
configurations. ECC DIMMs are supported.
Use the following guidelines in selecting DIMM types:
„
memory can be installed in one, two, three, or four
sockets
„
the size and speed of the DIMMs can vary between
sockets
„
single- and double-sided DIMMs are supported.
To determine what configuration of DIMMs to use, see the
table, “Supported DIMMs.” For sample memory
configurations, see the table “Sample DIMM Upgrade
Paths.” To locate memory module sockets on the system
board see the figure following the tables. To determine the
memory you need to purchase for a memory upgrade, see
“Checking System Memory.”
