52 Replacing and Adding Internal Devices
Adding memory
The DRAM DIMMs supported by the server board conform to the following
standards:
■64 MB, 128 MB, 256 MB, and 512 MB ECC DIMMs
■PC/100-compliant, unbuffered, ECC SDRAM
■64 MB minimum system memory
■2.0 GB maximum system memory
When you select and install DIMMs, keep the following in mind:
■Registered DIMMs should not be combined with unbuffered DIMMs
■Memory should be added in order, from DIMM 1 to DIMM 4.
■There can be no empty slots between installed DIMMs.
■No jumper settings are required for the memory size or type because the
BIOS automatically detects this information.

To add DIMMs:

1Turn off the system and disconnect the power cord and all other external
peripheral devices.
2Open the case. (See “Opening the case” on page 23 and “Preventing static
electricity discharge” on page 22.)
3Pull open the socket clamps on each side of the DIMM socket.
4Insert the new DIMM into the socket and align the two notches in the
DIMM with the two notches in the DIMM socket.
