Memory Configurations - Asus M3N78 SE User Manual

1.7.2

Memory configurations

You may install 512MB, 1GB, 2GB, and 4GB unbuffered ECC/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, we
recommend that you obtain memory modules from the same vendor. Refer to the DDR2
Qualified Vendors List below.
• 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.
