Notes

(Note 1) 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.

(Note 2) To support a DDR3 1866 MHz (and above) memory, you must install an AMD AM3+ CPU first.

(Note 3) 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.

(Note 4) 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.

(Note 5) Whether the CPU/system fan speed control function is supported will depend on the CPU/system cooler you install.

(Note 6) Available functions in EasyTune may differ by motherboard model.
