2.4System memory

2.4.1Overview

The motherboard comes with four Double Data Rate (DDR) Dual Inline Memory Modules (DIMM) sockets.

A DDR module has the same physical dimensions as a DDR2 DIMM but has a 184-pin footprint. DDR DIMMs are notched to match the break on the socket and ensure correct installation.

The figure illustrates the location of the DDR DIMM sockets:

2.4.2Memory configurations

You may install 256 MB, 512 MB and 1 GB registered ECC DDR DIMMs into the DIMM sockets.

•Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. Refer to the DDR Qualified Vendors List on the following URL for details.

•Due to chipset resource allocation, the system may detect less than 8 GB system memory when you installed four 2 GB DDR memory modules.

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