2.4.2 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. • 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. 64-bit Windows® XP Professional x64 Edition Windows® Vista x64 Edition • 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 vendormarked 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.

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

•
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

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.

•
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

The memory modules may require a better cooling system to work stably
under full loading (4 DIMMs) or overclocking setting.
