1.7.2 Memory configurations You may install 256MB, 512MB, 1GB and 2GB unbuffered non‑ECC DDR2 DIMMs into the DIMM sockets. • 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. • Due to the memory address limitation on 32-bit Windows OS, when you install 4GB or more memory on the motherboard, the actual usable memory for the OS can be about 3GB or less. For effective use of memory, we recommend that you install a 64-bit Windows OS when having 4GB or more memory installed on the motherboard. • This motherboard does not support DIMMs made up of 256 megabit (Mb) chips or less. Some old-version DDR2-800 DIMMs may not match Intel® On-Die-Termination (ODT) requirement and will automatically downgrade to run at DDR-667. If this heppens, contact your memory vendor to check to ODT value.

Memory configurations
You may install 256MB, 512MB, 1GB and 2GB unbuffered non-ECC DDR2 DIMMs into the
DIMM sockets.
•
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.
•
Due to the memory address limitation on 32-bit Windows OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you install a 64-bit
Windows OS when having 4GB or more memory installed on the motherboard.

This motherboard does not support DIMMs made up of 256 megabit (Mb) chips or less.
Some old-version DDR2-800 DIMMs may not match Intel

On-Die-Termination (ODT)
requirement and will automatically downgrade to run at DDR-667. If this heppens, contact
your memory vendor to check to ODT value.
