You may install varying memory sizes in Channel A and Channel B. The
system maps the total size of the lower-sized channel for the dual-channel
configuration. Any excess memory from the higher-sized channel is then
mapped for single-channel operation.
Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.
If you install four 1 or 2GB memory modules, the system may only recognize
less than 3GB because the address space is reserved for other critical
functions. This limitation appears on Windows
which does not support Physical Address Extension (PAE).
If you install Windows
than 3GB is recommended.
The total memory may has 8MB reduction under Single Channel mode, and
16MB reduction under Dual Channel mode because the address space is
reserved for Intel

Due to chipset limitation, double x16 memory modules or memory modules
with 128MB chips are not supported on this motherboard.
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 configuration.

Some old-version DDR2-800/667 DIMMs may not match Intel
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.
