1.7 System memory

1.7.1 Overview

The motherboard has three Double Data Rate (DDR) DIMM sockets that support

up to 3 GB unbuffered non-ECC DDR400/333/266 DDR SDRAM DIMMs. Each

DIMM socket is double-sided.

1.7.2 Memory configurations

You may install single or double-sided 64 MB, 128 MB, 256 MB, 512 MB, and 1 GB

DDR DIMMs to the sockets.

1. DIMMs with more than 8 devices on each side of the module are not supported.

2. Make sure the memory frequency and bus frequency setting in the BIOS are

the same or set to [Auto] ensure system stability.

3. A DDR DIMM is keyed with a notch so that it fits in only one direction. DO

NOT force a DIMM into a socket to avoid damaging the DIMM.

4. For optimum compatibility, it is recommended that you obtain memory

modules from qualified vendors. See the next page for a list of qualified

DDR400 DIMM vendors.

5. Visit ASUS website (www.asus.com) for latest DDR400 Qualified Vendor List.
