Memory cartridge population guidelines
When installing memory cartridges, observe the following guidelines:
•
Memory cartridges installed without a corresponding processor are not utilized:
o
Processor 1 corresponds to memory cartridges 1 and 2.
o
Processor 2 corresponds to memory cartridges 3 and 4.
o
Processor 3 corresponds to memory cartridges 5 and 6.
Memory cartridges 5 and 6 are not recognized if processor 3 is not installed.
o
Processor 4 corresponds to memory cartridges 7 and 8.
•
To maximize performance, install two memory cartridges per processor and balance the total memory
capacity between all installed processors.
•
UDIMMs are not supported.
•
Install DIMMs in pairs and in alphabetical order: A & B, C & D, E & F …
•
Do not mix LRDIMMs with any other DIMM type (RDIMM, LVDIMM).
•
RDIMM population is limited to a maximum of eight logical ranks per channel. Therefore, only two quad
rank RDIMMs are supported per channel. If there are more than eight physical ranks per channel,
LRDIMMs rank multiplication provides support for three DIMMs per channel.
•
1:1 Lockstep mode requires specific population requirements. For more information, see "Memory
configurations (on page
