2-14 Chapter 2: Hardware information
• If you install four 1 GB memory modules, the system may detect less than
3 GB of total memory because of address space allocation for other critical
functions. This limitation applies to Windows XP 32-bit version operating
system since it does not support PAE (Physical Address Extention) mode.
• If you install Windows XP 32-bit version operating system, we recommend
that you install less than 3GB of total memory.
Notes on memory limitations
• Due to chipset limitation, this motherboard can only support up to
8 GB on the operating systems listed below. You may install a maximum of
2 GB DIMMs on each slot, but only DDR2-533 and DDR2-667 2 GB density
modules are available for this conguration.
• Some old-version DDR2-800/667 DIMMs may not match Intel
®
’s
On-Die-Termination (ODT) requirement and will automatically downgrade to
run at DDR2-533. If this happens, contact your memory vendor to check the
ODT value.
• Due to chipset limitation, DDR2-800 with CL=4 will be downgraded to run
at DDR2-667 by default setting. If you want to operate with lower latency,
adjust the memory timing manually.
• Due to chipset limitation, DDR2-667 with CL=3 will be downgraded to run
at DDR2-533 by default setting. If you want to operate with lower latency,
adjust the memory timing manually.
