Hemisphere mode
With hemisphere mode, data will be distributed over two different sections for
better performance (upper hemisphere / lower hemisphere). The lower half of
the address space is stored in one Mbox, the upper half of the address space
in the other Mbox of the same CPU.
Hemisphere mode is possible with 2, 3 or 4 CPUs.
I
All DIMMS must be identical (same capacity and technology). A memory
board must have a capacity of 4, 8, 16, 32, 64 or 128 GB. The
configuration of the memory boards per CPU must be the same.
