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 slot.
(Note 4) The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot will operate at up to x8 mode.
(Note 5) The PCIEX16 slot operates at up to x8 mode when AMD CrossFireX is enabled.
(Note 6) Whether the CPU/system fan speed control function is supported will depend on the CPU/system cooler you install.
(Note 7) Available functions in EasyTune may differ by motherboard model.
