Note    (Note 1) Due to a 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 the size of the physical memory installed.

(Note 2) To support a DDR3 1866 MHz (and above) memory, you must install an 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) Be sure to connect your USB device(s) to the USB 2.0/1.1 ports before the USB 3.0 driver is installed.

(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.
Remark    

    Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website.
    Most hardware/software vendors may no longer offer drivers to support Win9X/ME/2000/XP SP1/SP2. If drivers are available from the vendors, we will update them on the GIGABYTE website.
