General Dimm Slot Population Guidelines; Multi-Processor Advanced Ecc Population Order - HP ProLiant DL G6 User Manual

General DIMM slot population guidelines

Observe the following guidelines for all AMP modes:
•
Populate DIMM slots for a processor only if the processor is installed.
•
To maximize performance in multi-processor configurations, distribute the total memory capacity
between all processors as evenly as possible.
•
Do not mix Unbuffered and Registered PC3 DIMMs.
•
Each channel supports up to two Unbuffered DIMMs.
•
If quad-rank DIMMs are installed for a processor, a maximum of two DIMMs can be installed on each
channel for that processor.
•
If a channel contains quad-rank DIMMs, the quad-rank DIMM must be installed first on that channel.
DIMM speeds are supported as indicated in the following table.

Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines (on page 50).
•
DIMMs may be installed individually.

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.
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.
Lockstep Memory population guidelines
For Lockstep memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines (on page 50).
