1.4.2Memory configurations

You may install 512MB, 1GB, 2GB, 4GB and 8GB unbuffered non‑ECC DDR3 SO-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 CPU limitation, 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 use a maximum of 3GB system memory.

•This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
