Table 3 DDR400 Qualified Vendor List (QVL)
Obtain DDR DIMMs only from ASUS qualified vendors for better system
performance. Visit the ASUS website (www.asus.com) for the latest QVL.
Make sure to unplug the power supply before adding or removing DIMMs or
other system components. Failure to do so may cause severe damage to both
the motherboard and the components.
Follow these steps to install a DIMM.
1. Unlock a DIMM socket by pressing
the retaining clips outward.
2. Align a DIMM on the socket such that
the notch on the DIMM matches the
break on the socket.
3. Firmly insert the DIMM into the socket
until the retaining clips snap back in
place and the DIMM is properly
seated.
