downgrade to run at DDR2-533. If this happens, contact your
memory vendor to check the ODT value.
Due to chipset limitation, DDR2-667 with CL=4 will be downgraded
to run at DDR2-533 by default setting. If you want to operate with
lower latency, adjust the memory timing manually.
Due to chipset limitation, DDR2-533 with CL=3 will be downgraded
to run at DDR2-400 by default setting. If you want to operate with

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 benet of manipulating this
excess memory space.
