vThe DIMM options that are available for the server are 1 GB, 2 GB, 4 GB, and 8 GB (when available). The sever supports a minimum of 1 GB and a maximum of 128 GB of system memory.

Note: The amount of usable memory is reduced depending on the system configuration. A certain amount of memory must be reserved for system resources. To view the total amount of installed memory and the amount of configured memory, run the Setup utility.

vA minimum of one DIMM must be installed for each microprocessor. For example, you must install a minimum of two DIMMs if the server has two microprocessors installed. However, to improve system performance, install a minimum of three DIMMs for each microprocessor.

vThe maximum operating speed of the server is determined by the slowest DIMM installed in the server.

DIMM installation sequence

vThe server comes with a minimum of two 1 GB DIMMs, installed in connectors 3 and 6. When you install additional DIMMs, install them in the order shown in the following table to optimize system performance. In non-mirroring mode, all three channels on the memory interface for each microprocessor can be populated in any order and have no matching requirements.

Memory mirroring

vThe server supports memory mirroring (mirroring mode):

–Memory-mirroring mode replicates and stores data on two pairs of DIMMs within two channels simultaneously. If a failure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pair of DIMMs. To enable memory mirroring through the Setup utility, select System Settings → Memory. When you use the memory mirroring feature, consider the following information:

-When you use memory mirroring, you must install a pair of DIMMs at a time. One DIMM must be in channel 0, and the mirroring DIMM must be in the same slot in channel 1. The two DIMMs in each pair must be identical in size, type, and rank (single or dual) , and organization, but not in speed. The channels run at the speed of the slowest DIMM in any of the channels.

-Channel 2, DIMM connectors 8 ,7, 15, and 16 are not used in memory-mirroring mode.

-The maximum available memory is reduced to half of the installed memory when memory mirroring is enabled. For example, if you install 64 GB of memory, only 32 GB of addressable memory is available when you use memory mirroring.

The following diagram shows the memory channel interface layout with the DIMM installation sequence for mirroring mode. The numbers within boxes indicate the DIMM population sequence in pairs within the channels, and the numbers next to the boxes indicate the DIMM connectors within the channels. For example, the following illustration shows the first pair of DIMMs (indicated by ones (1) inside the boxes) should be installed in DIMM connectors 3 on channel 0 and DIMM connector 6 on channel 1 DIMM connectors 7, 8, 15, and 16 on channel 2 are
