3.5 Main memory
3.5.1 5MMDDR.xxxx-02
3.5.1.1 General information
These 204-pin DDR3 main memory modules operate at 1066 MHz and are available with 2 GB and 4 GB.
If two RAM modules with the same size (e.g. 2 GB) are inserted into the CPU board, then dual-channel memory
technology is supported. This technology is not supported if two RAM modules of different sizes (e.g. 2 GB and
4 GB) are inserted.
If two 2 GB modules or one 4 GB module is installed on a 32-bit operating system, only 3 GB of main memory can
be used. On a 64-bit operating system, up to 8 GB of main memory can be used.
