Caution: Exercise extreme care when installing or removing DIMM modules to prevent damage
to the node board or DIMM module.
The SGI Altix XE250 node board supports up to 128 GB fully buffered (FBD) ECC DDR2
800/667 in 16 DIMM slots (four channels, two branches). Single channel memory, two-way
interleaved memory and four-way interleaved memory schemes are all supported. Using four-way
interleaved memory results in the best performance. There are a maximum of sixteen memory
DIMMs in each node board. Memory DIMMs must be populated in groups of two on the node
board. A minimum of two DIMMs must be installed on each node board. Refer to
memory DIMM locations.
