2.2.2 Memory (2/7)
Memory Installation Conditions
•
For one CPU, 1 to 12 sets of memory modules can be installed.
•
Memory must be added on a set basis.
(Add memory on a two-set basis when the Memory Mirror function is used or on a three-set basis when the
Memory Spare function is used.)
When only one set of memory module is installed, if one module fails, the SB is disconnected from the
PPAR block. Therefore, it is recommended to install at least two sets of memory modules.
•
Only the same memory modules can be installed to the same memory channel of each Memory Buffer.
Different memory modules can be installed for different memory channels.
•
When the Memory Mirror function is used, install the same configuration of memory (in size and the
number of modules) in multiple memory channels that are used for mirroring.
•
When the Memory Spare function is used, install the same memory modules in all six slots of the
same Memory Buffer.
A "memory channel" is a DDR3/DDR4
interface connected to a Memory Buffer.
"Same memory channel"
The same memory modules
must be installed.
* MB: Memory Buffer
"Same memory channel"
The same memory modules
must be installed.
