Asus P4PE-X 1.9.1 Memory configurations, DDR DIMM1, DDR DIMM2, DDR DIMM3, Chapter 1: Product introduction

1.9System memory

The motherboard comes with three Double Data Rate (DDR) Dual Inline Memory Module (DIMM) sockets. These sockets support up to 2GB system memory using 184-pin unbuffered non-ECC PC3200/2700/2100/1600 DDR DIMMs. The following figure illustrates the location of the DDR DIMM sockets.

If you wish to use a PC3200 (400MHz) DDR module, you need to install a CPU with 800MHz FSB.

1.9.1 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

1.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.

2.You may install single-sided DIMMs into DIMM2 and DIMM3 sockets at the same time but neither one can be 16-bit DDR module.

3.Double-sided 16-bit DDR DIMMs are not supported on this motherboard.
