Memory configurations
You may install 512 MB, 1 GB, 2 GB, and 4 GB unbuffered non-ECC DDR2 DIMMs
into the DIMM sockets.
Recommended Memory Configurations
• 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
configuration. 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.
