* Due to Windows 32-bit operating system limitation, when more than 4 GB of physical
memory is installed, the actual memory size displayed will be less than 4 GB.
* To support a DDR3 1866 MHz (and above) memory, you must install an AM3+ CPU
first.

* For optimum performance, if only one PCI Express graphics card is to be installed, be
sure to install it in the PCIEX16_1 slot; if you are installing two PCI Express graphics
cards, it is recommended that you install them in the PCIEX16_1 and PCIEX16_2
slots.
* The PCIEX8 slot shares bandwidth with the PCIEX16_2 slot. When PCIEX8 is
populated with a PCI Express expansion card, the PCIEX16_2 slot will operate
at up to x8 mode.
