ASUS P5Q SE 2-13

2.4.2 Memory congurations

You may install 512 MB, 1 GB, 2 GB, and 4 GB unbuffered non-ECC DDR2 DIMMs

into the DIMM sockets.

Recommended Memory Congurations

• 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.

• It is recommended to install the memory modules from the yellow slots for

better overclocking capability.

• Always install DIMMs with the same CAS latency. For optimum compatibility,

it is recommended that you obtain memory modules from the same vendor.

• When installing total memory of 4GB capacity or more, Windows

32-bit

operation system may only recognize less than 3GB. Hence, a total

installed memory of less than 3GB is recommended.

• This motherboard does not support memory modules made up of 128 Mb

chips.

64-bit

Windows

XP Professional x64 Edition

Windows

Vista x64 Edition

• Due to chipset limitation, this motherboard can support up to

16 GB on the operating systems listed below. You may install a maximum

of 4 GB DIMMs on each slot.

• The default memory operation frequency is dependent on its SPD. Under

the default state, some memory modules for overclocking may operate at a

lower frequency than he vendor-marked value. To operate at the vendor-

marked or at a higher frequency, see section 4.4 Ai Tweaker menu for

manual memory frequency adjustment.

• The memory modules may require a better cooling system to work stably

under full loading (4 DIMMs) or overclocking setting.
