•
Observe the general DIMM slot population guidelines (on page
•
DIMMs may be installed individually.
Single-processor Advanced ECC population order
For Advanced ECC mode configurations with a single processor, populate the DIMM slots in the following
order:
•
RDIMM: Sequentially in alphabetical order (A through I)
•
UDIMM: A through F, sequentially in alphabetical order. Do not populate DIMM slots G through I.
Multi-processor Advanced ECC population order
For Advanced ECC mode configurations with multiple processors, populate the DIMM slots for each
processor in the following order:
•
RDIMM: Sequentially in alphabetical order (A through I)
•
UDIMM: A through F, sequentially in alphabetical order. Do not populate DIMM slots G through I.
Lockstep Memory population guidelines
For Lockstep memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines (on page
•
Always install DIMMs in channels 1 and 2 for each installed processor.
•
Do not install DIMMs in channel 3 for any processor.
•
DIMM configuration on channel 1 and channel 2 of a processor must be identical.
•
In multi-processor configurations, each processor must have a valid Lockstep Memory configuration.
•
In multi-processor configurations, each processor may have a different valid Lockstep Memory
configuration.
Single-processor Lockstep population order
For Lockstep memory mode configurations with a single processor, populate the DIMM slots in the following
order:
•
RDIMM
o
First: A and B
o
Next: D and E
o
Last: G and H
o
Do not populate slots C, F, or I.
•
UDIMM
o
First: A and B
o
Last: D and E
o
Do not populate slots C, F, G, H, or I.
After installing the DIMMs, use RBSU to configure the system for Lockstep memory support ("
