ASUS P5K Premium 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 figure illustrates the location of the DDR2 DIMM sockets:

• This chipset officially 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 officially
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 Configuration for details.
