Asus P4B533 2.5.2 Memory configurations, 2.5.3 Installing a DIMM, DDR DIMM1, DDR DIMM2, DDR DIMM3

2.5.2 Memory configurations

You may install any DDR DIMMs with 64MB, 128MB, 256MB, 512MB, and 1GB densities into the DIMM sockets.

Use only the following combinations to install DDR DIMMs. Otherwise, the system may not boot up.

DDR DIMM1	DDR DIMM2	DDR DIMM3
(Rows 0&1)	(Rows 2&3)	(Rows 3&2)
SS/DS	DS	None
SS/DS	SS	SS

*SS - Single-sided DIMM DS - Double-sided DIMM

DDR DIMM sockets 2 and 3 share the same rows, so if you install a double-sided DIMM into DIMM2 socket, you must leave DIMM3 socket empty. However, you may install single-sided DIMMs into DIMM2 and DIMM3 sockets at the same time.

2.5.3 Installing a DIMM

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.
