General DIMM slot population guidelines

•
The HP ProLiant DL120 G6 Server has six memory slots.
•
There are two channels per server with three DIMM slot per channel.
•
Memory channel 1 consists of the three (3) DIMMs that are closest to the processor
•
Memory channel 2 consists of the three (3) DIMMs that are furthest from the processor
•
Different types of processors have different types of memory support.
•
The server supports up to 12 GB (6 x 2-GB) for Registered Memory configurations.
•
The server supports up to 16 GB (4 x 4-GB) for Unbuffered Memory configurations.
Observe the following guidelines when installing DIMMs:
•
Do not mix Unbuffered and Registered PC3 DIMMs.
•
Do not mix DIMMs of varying speeds.
•
Do not mix DIMMs of varying voltages.
•
Do not mix Unbuffered memory (UDIMMs) with Registered memory (RDIMMs).
•
Do not install DIMMs if the processor is not installed.
•
Populate DIMMs from heaviest load (double-rank) to lightest load (single-rank) within a channel.
•
Heaviest load (DIMM with most ranks) within a channel goes furthest from the CPU.
•
Non-ECC DIMMs are not supported
•
Each channel supports up to two Unbuffered DIMMs.
•
When using UDIMMs, use ECC only.
•
When possible, balance the loads per channel.
•
If quad-rank DIMMs are installed for the 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.
•
256MB technology, x4 DRAM on UDIMMs and quad-rank UDIMMs are not supported.
•
Always use HP qualified DIMMs.
Populate the DIMM slots in the following sequence:
•
DIMM 3A and DIMM 6B
•
DIMM 2C and DIMM 5D
•
DIMM1E and DIMM 4F
