memory cards with eight GB of memory activated. The maximum memory

capacity depends on the number of processor books ordered for the system and

on the type of memory and functionality required.

Memory placement

The following rules should be followed for Model 595 memory.

Minimum memory

Note: For best performance order sufficient memory to balance memory

across MCM and processor books.

Each processor book must have at least two pairs of memory cards (one pair

for each MCM). The recommended minimum memory is shown in the

following table:

Memory must be ordered in identical pairs.

Each processor book must have a minimum of four memory cards on it.

Spread memory across the processor books.

Select memory cards to enable equal memory configurations across

processors in an n-way unit. If memory greater than the minimum is ordered,

select memory features to drive the most number of memory cards onto the

system, as evenly distributed across the processors as possible.

Spread existing memory onto the new processor cards in any new processor

and enclosure additions

Memory increments are handled by the IBM marketing configurator
