Main memory
Hemisphere Mode with 2 CPUs and 4 Memory Boards
Figure 16: Upgrade configuration for 2 CPUs and 4 memory boards
For the first upgrade step 8 DIMMs (red color) must be added.
Remember: Capacity per memory board must be 4, 8, 16, 32, 64 or 128 GB and
the configuration of the memory boards per CPU must be the same.
For the second upgrade step, 16 DIMMs (green color) must be added, because
both channels (ch. 1 & ch. 2) must be configured the same way. Since channel
1 is equipped with 16 DIMMs after the first upgrade step, channel 2 also has to
be equipped with 16 DIMMs.
I
The same upgrade rules have to be applied for configurations with 3 and
4 CPUs.
