System Memory
You can upgrade your system memory to a maximum of 128 GB (two-
processor configurations) or 256 GB (four-processor configurations) by
installing sets of 512-MB, 1-GB, 2-GB, 4-GB, or 8-Gb (when available)
memory modules. 667-MHz registered DDR-II memory modules are
supported in all memory sizes. 2-GB and 4-GB (when available) 800-Mhz
memory modules are also supported in restricted configurations.
Sixteen memory sockets are located on the system board under the cooling
shroud assembly. In four-processor systems, sixteen additional sockets are
located on the processor expansion module board (PEM). Each processor has
two memory channels, organized in sets of four memory module slots per
channel.
