Memory Minimums: Each processor card must have at least one set of

memory DIMM placed on it. As memory is in features codes of quads. The

following memory minimums have been established:

Balancing: Each 0/2 way processor card must have a minimum of 2 GB

memory on it.

Spreading: Memory should be spread across the processor cards. Memory

DIMM's should be selected to enable equal memory configurations across

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

the selection of memory features should be based on driving the most

number of DIMM quads onto the system, as evenly distributed across the

processors as possible.

#4492 8GB Dimms: The 8GB DIMM's carry the following restrictions:

– 8GB Dimms cannot be placed on a processor card with another size

– 8GB Dimms slow the system memory clock down from 266MHz to 200

As a result, #4492 can only be placed on a processor card by itself, with

another #4492, or with a #7935.

Processor additions / Enclosure additions: Existing memory should be

spread onto the new processor cards or the additional processors should ship

with memory.
