The following notes describe the types of dual inline memory modules (DIMMs) that the server supports and other information that you must consider when you install DIMMs:

Use the system summary in the Configuration/Setup Utility program to view the total amount of installed memory and the amount of configured memory (see “Using the Configuration/Setup Utility program” on page 38).
vThe server comes with one 512 MB or 1 GB DIMM installed in DIMM connector 1 and an identical DIMM (the same size, speed, type, and technology) installed in DIMM connector 3.
vIf you install a pair of DIMMs in DIMM connectors 2 and 4, the size, speed, type, and technology of the DIMMs that you install in DIMM connectors 2 and 4 must match each other. However, they do not have to be the same size, speed, type, and technology as the DIMMs that are installed in DIMM connectors 1 and 3.
vYou can use compatible DIMMs from various manufacturers in the same pair.
