1.7.1 Overvi ew

The motherboard comes with two 240-pin 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. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket.

The following figure illustrates the location of the sockets:

1.7.2 Memory confi gurati ons

You may install 256 MB, 512 MB, and 1 GB unbuffered non-ECC DDR2 DIMMs into the DIMM sockets using the memory configurations in this section.

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 DDR2 Qualified Vendors List on the next page for details.

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