System Memory
Your system supports DDR3 registered memory modules (RDIMMs) or ECC
unbuffered memory modules (UDIMMs). Single and dual-rank memory
modules can be 1067- or 1333-MHz, and quad-rank memory modules can be
1067-MHz.
The system contains 12 memory sockets split into two sets of six sockets, one
set per each processor. Each six-socket set is organized into three channels of
two memory sockets per channel. 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 types and sizes of memory modules being used:
