1.7.2 Memory configurations
You may install 256MB, 512MB, 1GB, and 2GB unbuffered non-ECC DDR2 DIMMs into the
DIMM sockets.
• 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 do any of the
following:
- Use a maximum of 3GB system memory if you are using a 32-bit Windows
®
OS.
- Install a 64-bit Windows
®
OS when you want to install 4GB or more memory on
the motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) or less.
Notes on memory limitations
• Due to chipset limitation, this motherboard can only support up to
4 GB on the operating systems listed below. You may install a maximum of 2 GB DIMMs
on each slot, but only DDR2-800 and DDR2-667 2 GB density modules are available for
this configuration.
• 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.
