Memory frequency/CPU FSB synchronization

The system motherboard supports different memory frequencies depending on the CPU FSB (Front Side Bus) and the type of DDR DIMM.

800 MHz

PC3200/PC2700*/PC2100

400/333*/266 MHz

 

533 MHz

PC2700/PC2100

333/266 MHz

 

400 MHz

PC2100

266 MHz

 

 

 

 

*When using 800 MHz CPU FSB, PC2700 DDR DIMMs may run only at 320 MHz (not 333 MHz) due to chipset limitation.

2.7.2DIMM installation

To install a DDR DIMM:

1.Locate the two DIMM sockets on the motherboard.

2.Unlock a socket by pressing the retaining clips outward.

3.Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket.

4.Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated.

Retainin g clips

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!
