Memory configurations
You may install 1GB, 2GB, 4GB, and 8GB unbuffered ECC and non-ECC DDR3 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. 
•  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 512 megabits (Mb) chips or less.
