If the configuration is two quad-rank 8-GB DIMMs and six dual-rank 8-GB DIMMs in a single
cartridge configuration, the quad-rank DIMMs can be located in either of the corresponding
white DIMM pairs (1A/8A or 3B/6B) as long as they are installed at the end point of the DDR3
channel.
• AMP modes Advanced ECC, Online Spare, and Mirrored Memory have further requirements
beyond the ones listed here. For additional memory configuration requirements, see the
corresponding AMP sections:
o Advanced ECC memory population guidelines (on page 48)
o Online Spare memory population guidelines (on page 48)
o Mirrored Memory population guidelines (on page 49)
Memory cartridge population guidelines
This server contains eight memory cartridge slots in the processor memory drawer.
Observe the following guidelines:
• Populate memory cartridge slots for a processor only if the corresponding processor is installed:
o Processor 1 connects to the memory cartridge in slots 1 and 2.
o Processor 2 connects to the memory cartridge in slots 3 and 4.
o Processor 3 connects to the memory cartridge in slots 5 and 6.
o Processor 4 connects to the memory cartridge in slots 7 and 8.
• Memory is only accessible to the system if the associated processor is installed. Do not install
memory cartridges in cartridge slots without the corresponding processor installed.
• The minimum memory cartridge population is one per processor. For best performance, two memory
cartridges per processor are recommended.
• Due to higher memory access latencies, HP does not recommend installing a processor without its
corresponding memory cartridges.
• To maximize performance in multi-processor configurations, distribute the total memory capacity
evenly across all processors.
