Memory Cartridge population guidelines
This server contains 8 memory cartridge slots in the processor memory drawer. Observe the following guidelines:
This server contains 8 memory cartridge slots in the processor memory drawer. Observe the following guidelines:
Populate memory cartridge slots for a processor only if the processor is installed where:
Processor 1 connects to cartridge slots 1 and 2.
Processor 2 connects to cartridge slots 3 and 4.
Processor 3 connects to cartridge slots 5 and 6.
Processor 4 connects to cartridge slots 7 and 8.
Processor 2 connects to cartridge slots 3 and 4.
Processor 3 connects to cartridge slots 5 and 6.
Processor 4 connects to cartridge slots 7 and 8.
Minimum recommended cartridge population is one cartridge per processor. For best performance two cartridges per processor
are recommended.
Processors installed without corresponding memory cartridges will incur high memory access latencies and is not
recommended.
To maximize performance in multi-processor configurations distribute the total memory capacity evenly between all
processors.

Hemisphere mode
The architecture incorporates hemisphere mode, a high performance interleaving technology. Hemisphere mode allows interleaving
between the two processor memory controllers internal to each processor.
The architecture incorporates hemisphere mode, a high performance interleaving technology. Hemisphere mode allows interleaving
between the two processor memory controllers internal to each processor.
Hemisphere mode is enabled when all processors in a system have the memory behind both memory controllers populated identically.
To enable each processor to enter hemisphere mode it must have both cartridges installed, populated with equal memory
capacities and follow the DIMM installation guidelines.
