• When using only one memory module, start installing the DDR2 DIMM from

slot DIMM_A1 or DIMM_B1 for better overclocking capability.

• For dual-channel configuration (2), you may:

- install identical DIMMs in all four sockets OR

- install identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow sockets)

and another identical DIMM pair in DIMM_A2 and DIMM_B2 (black

sockets)

• Due to the chipset’s limitation, the 1066 MHz memory modules run at 1066

MHz only when:

- two 1066 MHz memory modules installed in the same colored-slots

(either in the yellow slots or black slots); and

- one 1066 MHz memory module installed in any of the slots.

In other cases, the 1066 MHz memory modules can only run at

800 MHz.

• Always use identical DDR2 DIMM pairs for dual channel mode. For

optimum compatibility, we recommend that you obtain memory modules

from the same vendor.

• If you are using a Windows 32-bit version operating system (e.g. 32-bit

Windows, 32-bit Vista), the system will allocate a certain amount of memory

space for system devices.

• 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.
