System Memory

Your system supports ECC DDR3 registered DIMMs (RDIMMs) and unbuffered registered DIMMs (UDIMMs). Quad-rank DIMMs of 1066 MHz and single- and dual-rank DIMMs of 1333 MHz are also supported. RDIMMs of capacities 2 GB, 4 GB, and 8 GB are supported for a total of up to 256 GB.

The system consists of 32 memory sockets split into four sets of eight sockets; one set for each processor. Each eight-memory socket set is further organized into four DDR3 memory channels. The first socket of each DDR3 memory channel is marked with a white release lever.

Each channel supports up to two single-, dual-, or quad-rank RDIMMs or two UDIMMs. The interface uses either 2 GB, 4 GB, or 8 GB RDIMMs and 1 GB, 2 GB, or 8 GB UDIMMs.

The following features are available with respect to memory:

•Each processor has four DDR3 channels that support speeds up to 1333 MHz.

•UDIMMs and RDIMMs cannot be mixed.

•Quad-Rank DIMM types support speeds up to 1066 MHz.

•Your system may support online memory sparing.

•Mixing of memory sizes and ranks is allowed for flexibility.

•Up to 256 GB of memory (with 32 8 GB RDIMMs)
