* For dual-channel memory conguration (2), you may:

• install identical DIMMs in all four sockets OR

• install an identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow sockets) and another identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)

* Always use identical DDR2 DIMM pairs for dual-channel model. For

optimum compatibility, we recommend that you obtain memory modules from the same vendor. Visit the ASUS website (www.asus.

com) for the latest Qualied Vendors List.

Important notice on installing Windows® XP 32-bit version

If you install Windows® XP 32-bit version Operating System (OS), the limitation of this OS version is that it may reserve a certain amount of memory space for system devices. We recommend that you install less than 3 GB system memory if you would like to work under Windows

32-bit version OS. The excess memory installation will not cause any
