DDR3 memory population guidelines

NOTE:

Memory configurations listed do not apply to Factory Integrated Models .

Click here to use Online DDR3 Memory Configuration Tool for detailed memory configuration rules and guidelines .

Some DIMM installation guidelines are summarized below:

For servers with eighteen (18) memory slots:
- There are three (3) channels per processor; six (6) channels per server
- There are three (3) DIMM slots for each memory channel; eighteen (18) total slots
- Memory channel 1 consists of the three (3) DIMMs that are closest to the processor
- Memory channel 3 consists of the three (3) DIMMs that are furthest from the processor
DIMM slots that are white should be populated first
Do not mix Unbuffered memory (UDIMMs) with Registered memory (RDIMMs)
Do not install DIMMs if the corresponding processor is not installed
If only one processor is installed in a 2CPU system, only half of the DIMM slots are available
To maximize performance, balance the total memory capacity between all installed processors
It is not required, but it is recommended to load the channels similarly if possible
If any Quad rank DIMMs are installed, all channels are limited to only 2 DIMMs per channel.
You can only install two quad-rank DIMMs per channel
You can only install two UDIMMs per channel; if available, the third slot in the channel must remain empty
Populate DIMMs from heaviest load (quad-rank) to lightest load (single-rank) within a channel
Heaviest load (DIMM with most ranks) within a channel goes furthest from the chipset
For memory mirroring mode, channel 3 must be unpopulated. Channels 1 and 2 are populated identically
For lock-step mode, channel 3 must be unpopulated. DIMMs in channels 1 and 2 will be installed in pairs. The paired slots will be 1,4; 2,5; 3;6 on a 3DPC system or 1,4; 2,5; on a 2DPC system
If mixing DIMM voltage is a requirement, please note that the DIMMs will run at 1.5V since all 1.35V are capable of supporting 1.5V operations

NOTE:

supported with ROM update via ROM Based Setup Utility (RBSU). UDIMM support is only on 12-slot servers

NOTE:

Mixing DIMM speeds is allowed, but the system processor speed rules always override the DIMM capabilities
If you do mix DIMM speeds, the memory bus will default to the minimum clock rate of all DIMMs in the system - even if the slower DIMM is on the other processor
If you install 1x 1066 MHz DIMM in channel 1 and 1x 1333 MHz DIMM in channel 2, you still run at 1066MHz
If you install 1x 1066 MHz DIMM in channel 1 and 5x 1333 MHz DIMMs with 1 DIMM Per Channel (DPC) in each of the other channels, you run at 1066 MHz
If you install 3DPC in one channel (if applicable) and 1DPC in all other channels, you run at 800 MHz
95 Watt CPU's are required for 1333MHz DIMM speeds. All other CPU's are capable of up to 1067 MHz
References to the above MHz speeds are for the various speeds of DDR3 DIMMs; 1333 refers to DDR3-1333, etc.
