HP 584087-421 Manual De Usuario

The DL580 G7 supports 64 DIMMs across four 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 architecture. Reference the Figure: Hemisphere Population Diagram to achieve the best performance for a given
memory/processor configuration.

The largest contributor to maximum memory bandwidth performance is to utilize both memory controllers inside the processor.
This is achieved by populating both memory cartridges for each installed processor.
The second 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.
Best performance is obtained when all installed processors are enabled for Hemisphere mode. HP recommends two memory
boards per processor- each one with at least 4 DIMMs- for improved memory bandwidth
Hemisphere mode is optimum when four or eight DIMMs are installed per cartridge. Hemisphere mode can be reached with
two or six DIMMs per cartridge (2 cartridges per processor) but it is not optimal configuration for Hemisphere mode.
Plan your memory configurations using Identical DIMMs to reach your memory size target taking into account that 32 and 64
DIMM count configurations result in the highest performance. For a 4 processor example:

If initial memory target is 64GB then populate a 4 processor system with eight cartridges of 4 - 2GB DIMMs each for a
total of 32 DIMMs. Your maximum expansion target is 128GB with 64 2GB DIMMs.
For 4GB DIMMs your initial memory target is 128GB using 32 DIMMs. Your maximum expansion target is 256GB with
64 DIMMs.
For 8GB DIMMs your initial memory target is 256GB using 32 DIMMs. Your maximum expansion target is 512GB with
64 DIMMs.
Maximum system memory capability is reached with an initial memory target of 512GB with 32 - 16GBDIMMs and 2TB
with 64 32GB DIMMs.

The more ranks per DIMM the higher the performance such that Quad rank DIMMs perform better than dual rank DIMMs.
