2.3System memory

2.3.1Overview

The motherboard comes with six (6) Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM.

The figure illustrates the location of the DDR2 DIMM sockets:`

DSAN-DX

128 pins

112 pins

DIMM_B1

DIMM_A1

DIMM_B2

DIMM_A2

DIMM_B3 DIMM_A3

DSAN-DX/TS500-E5 240-pin DDR2 DIMM sockets

2.3.2Memory configurations

You may install 512 MB, 1 GB, 2 GB, and 4 GB registered ECC DIMMs into the DIMM sockets.

• For optimum compatibility, we recommend that you obtain memory modules

from the same vendor. Refer to the Qualified Vendors List on the ASUS web site.

•This motherboard does not support memory modules made up of 128 Mb chips x16 memory modules.

•If you are installing only one memory module, install the module into the blue socket labeled DIMM_A1 or DIMM_B1. Installing into any other socket will not work.
