Unbuffered DIMMs (UDIMMs)

The following notes provide information that you must configure when you install UDIMMs:

vThe memory channels run at the fastest common frequency of the DIMMs installed.

vDo not use both UDIMMs and RDIMMs in the same server.

vUsing ECC and non-ECC UDIMMs in the server will cause the server to run in non-ECC mode.

vThe UDIMM options that are available for the server are 1 GB, 2 GB, and 4 GB (when available) DIMMs.

vYou can install a maximum of 16 GB of memory in some server models when you use UDIMMs.

vThe server supports up to two single-rank or dual-rank UDIMMs per channel.

vDIMM slots 3 and 6 are not supported when you install UDIMMs in the server. Do not install DIMMs in these connectors.

vThe following table lists the supported UDIMM population.

Registered DIMMs (RDIMMs)

The following notes provide information that you must consider when you install RDIMMs:

vThe memory channels run at the fastest common frequency of the installed DIMMs.

vRDIMMs are supported in models with an Xeon 3400 series processor.

vDo not use both RDIMMs and UDIMMs in the same server.

vThe server supports up to three single-rank, dual-rank, or quad-rank RDIMMs per channel.

vThe RDIMM options that are available for the server are 1 GB, 2 GB, 4 GB, and 8 GB (when available) DIMMs.

vYou can install a maximum of 32 GB of memory in the server when you use RDIMMs.
