2.4 System memory

2.4.1 Overview

The motherboard comes with four Double Data Rate (DDR) Dual Inline

Memory Module (DIMM) sockets.

The following figure illustrates the location of the sockets.

2.4.2 Memory configurations

You may install 64MB, 128MB, 256MB, 512MB, and 1GB unbuffered ECC

and non-ECC DDR DIMMs into the DIMM sockets using the memory

configurations in this section.

Important notes on memory configurations

• Installing DDR DIMMs other than the recommended configurations

may cause memory sizing error or system boot _ure. Use any of

the recommended configurations in Table 1.

• In Dual-channel configurations, install only identical (the same type

and size) DDR DIMM pairs for each channel.

• Use the blue DIMM slots first.

• Stacked RAM and DDR DIMM modules with more than 18 chips

are not supported.

• Always install DIMMs with the same CAS Latency. For optimum

compatibility, obtain memory modules from the same vendors. See

Qualified Vendors List on page 2-13.

• When all four sockets are populated with 1GB DIMMs (total 4GB),

the system may detect only 3+GB (a little less than 4GB) due to

the Southbridge resource allocation.
