Installing a memory moduleThe following notes describe the types of dual inline memory modules (DIMMs) thatthe server supports and other information that you must consider when you installDIMMs:v The server supports industry-standard, 667 MHz, unbuffered PC2-5300,double-data-rate 2 (DDR2) dual inline memory modules (DIMMs) error correctingcode (ECC) memory.v The system board contains four DIMM connectors and supports two-way memoryinterleaving.v The DIMM options that are available for the server are 512 MB, 1 GB, and 2 GB.The server supports a minimum of 512 MB and a maximum of 8 GB of systemmemory.v The server comes with one 512 MB DIMM or two 512 MB DIMMs installed.v The amount of usable memory will be reduced depending on the systemconfiguration. A certain amount of memory must be reserved for systemresources. To view the total amount of installed memory and the amount ofconfigured memory, run the Configuration/Setup Utility program and selectSystem Summary from the menu. For additional information, see the User’sGuide on the IBM System x Documentation CD.v For two-way memory interleaving, DIMMs must be installed in matched pairs.If one DIMM is installed in the DIMM 1 connector, when you install an additionalDIMM, it must be installed in the DIMM 3 connector, and it must be the samesize, speed, type, and technology as the DIMM in the DIMM 1 connector. Youcan mix compatible DIMMs from various manufacturers.If you install a second pair of DIMMs in the DIMM 2 and DIMM 4 connectors,they do not have to be the same size, speed, type, and technology as theDIMMs in the DIMM 1 and DIMM 3 connectors. However, the size, speed, type,and technology of the DIMMs that you install in the DIMM 2 and DIMM 4connectors must match each other.v Install only 1.8 V, 240-pin, double-data-rate 2 (DDR2), 667 MHz, PC2-5300,unbuffered synchronous dynamic random-access memory (SDRAM) with errorcorrecting code (ECC) DIMMs. These DIMMs must be compatible with the latestDDR2 667 MHz SDRAM unbuffered DIMM specification. For a list of supportedoptional devices for the server, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.v When you restart the server after you add or remove a DIMM, the serverdisplays a message that the memory configuration has changed.Chapter 2.
