2.4.1 Overvi ew

The motherboard comes with four 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 figure illustrates the location of the DDR2 DIMM sockets:

2.4.2 Memory confi gurati ons

You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC or non-ECC DDR2-533/667 DIMMs into the DIMM sockets.

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

compatibility, we recommend that you obtain memory modules from the same vendor. Refer to the DDR2 Qualified Vendors List on the ASUS web site.

•When installing one or two DIMMs, install the DIMM(s) to the blue slots (DIMM_A2/DIMM_B2).

•Three DDR2 DIMMs intalled into any three memory sockets will function in single-channel mode.
