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.
