* For dual-channel memory conguration (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

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® XP 32-bit version OS. The excess
memory installation will not cause any usage problem, but it will not give users
the benet of manipulating this excess memory space.
