2.3System memory

2.3.1Overview

The motherboard comes with sixteen (16) Double Data Rate 3 (DDR3) Dual Inline Memory Modules (DIMM) sockets.

The figure illustrates the location of the DDR3 DIMM sockets:

2.3.2Memory Configurations

You may install 1GB/2GB/4GB/8GB/16GB Registerd or 1GB/2GB/4GB Unbuffered with ECC/Non-ECC DDR3 DIMMs into the DIMM sockets using the memory configurations in this section.

• Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

•For CPU1 configuraton, install DIMMs from the orange slots and in the order as follows: DIMM_A2 -> DIMM_C2 -> DIMM_B2 -> DIMM_D2.

For CPU1 + CPU2 configuraton, install DIMMs from the orange slots and in the order as follows: DIMM_A2 -> DIMM_E2 -> DIMM_C2 -> DIMM_G2.

•For Quad Ranks DIMMs, when installing less than or equal to four DIMMs:

For CPU1 configuration, install DIMMs to the orange slots and in the order as follows: DIMM_A2 -> DIMM_C2 -> DIMM_B2 -> DIMM_D2.

For CPU1 + CPU2 configuration, install DIMMs to the orange slots and in the order as follows: DIMM_A2 -> DIMM_E2 -> DIMM_C2 -> DIMM_G2.

•For Quad Ranks DIMMs, when installing more than four DIMMs:

For CPU1 configuration, install DIMMs in the order as follows: DIMM_A2 -> DIMM_C2 -> DIMM_B2 -> DIMM_D2 -> DIMM_A1 -> DIMM_C1 -> DIMM_B1 -> DIMM_D1.

For CPU1 + CPU2 configuration, install DIMMs in the order as follows: DIMM_A2 -> DIMM_E2 -> DIMM_C2 -> DIMM_G2 -> DIMM_B2 -> DIMM_F2 -> DIMM_D2 -> DIMM_H2 --> DIMM_A1 -> DIMM_E1 -> DIMM_C1 -> DIMM_G1 -> DIMM_B1 -> DIMM_F1 -> DIMM_D1 ->

DIMM_H1.
