1.7.2 Memory congurations

You may install 512MB, 1GB, 2GB, and 4GB unbuffered ECC and 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 conguration. 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, we

recommend 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:

- Install a maximum of 3GB system memory if you are using a 32-bit Windows

OS.

- Use a 64-bit Windows

OS if 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.
