1-4 Chapter 1: Product introduction
1.4.2 Memory congurations
You may install 512MB, 1GB, 2GB, and 4GB 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 conguration. 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 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) chips or less.
This motherboard supports up to 8GB on Windows
®
XP Professional x64 and Windows
®
Vista x64 editions. You may install a maximum of 4GB DIMMs on each slot.
