ASUS P5K/EPU 2-13

2.4 System memory

2.4.1 Overview

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 gure illustrates the location of the DDR2 DIMM sockets:

• This chipset ofcially supports DDR2-800 MHz. With the ASUS Super

Memspeed Technology, this motherboard natively supports up to

DDR2-1066 MHz and provides more ratio setting items than the chipset

ofcially supports. See the table below.

• *If you install a DDR2-1066 memory module, make sure that you set the

DRAM Frequency item in BIOS to [DDR2-1066MHz]. See section 4.4.1

Jumperfree Conguration for details.
