processor have matching memory configurations. If the two memory configurations are not equal, the DL980 G7 will ignore (waste) the
extra memory in the larger configuration.
Memory Performance Optimization
The DL980 G7 supports 128 DIMMs across eight multi-core processors. While there are many DIMM population configurations that can
support any desired total memory size, optimal performance can only be achieved when DIMMs are populated to take advantage of the
Xeon EX architecture. The largest contributor to performance is to populate each DDR3 channel in each memory cartridge. To achieve
this, the minimum DIMM count per cartridge is four. Maximum bandwidth is reached by fully populating all memory cartridges with the
maximum number of eight DIMMs per cartridge.
The more ranks per DIMM the higher the performance, so Quad rank DIMMs perform better than dual rank DIMMs.
Performance is best when the installed DIMMs are all of equal size.
NOTE:
Memory configurations listed do not apply to "Factory Integrated Models". Only registered (RDIMM) speeds of 1066 or 1333
running at 1066 are supported. UDIMMs are not supported.
