System Memory
Your system supports DDR3 registered DIMMs (RDIMMs). Single-, dual-,
and quad-rank DIMMs can be 1067 MHz or 1333 MHz.
The system contains eight memory risers split into four sets of two risers per
processor. Figure 3-5 shows the order of the memory risers in the system. Each
memory riser has eight DIMM sockets arranged into four channels. The first
socket of each channel is marked with white release levers.
The maximum memory that is supported on your system varies according to
the sizes of memory modules being used. Single-rank, dual-rank, and quad-
rank RDIMMs of sizes 1 GB, 2 GB, 4 GB, 8 GB, and 16 GB are supported for
a total of up to 1 TB.
NOTE: Depending on the amount of memory installed, the system may take up to 3
minutes to display video on the screen.
