ASUS P5LD2-X/GBL 2-13
2.4 System memory
2.4.1 Overview
The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
The gure illustrates the location of the DDR2 DIMM sockets:

• You may install varying memory sizes in Channel A and Channel B. The
system maps the total size of the lower-sized channel for the dual-channel
conguration. Any excess memory from the higher-sized channel is then
mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor. Refer to the DDR2 Qualied Vendors List on the next page
for details.
• If you are using a Windows 32-bit version operating system (e.g. 32-bit
Windows XP, 32-bit Vista) without the Physical Address Extension (PAE)
support, the system will allocate a certain amount of memory space for
system devices.
• We recommend that you install only a maximum of 3GB system memory
when using a Windows 32-bit version operating system without the PAE.
The excess over 3GB of installed memory will not cause any problem;
however, the system can not use this excess memory space and the
system will display less than the total size of physical memory installed.
