Gigabyte GA-990FXA-UD3 AMD 990FX SB950 ATX AM3+ USB3.0 CrossfireX SLI RAID Motherboard

Gigabyte GA-990FXA-UD3 AMD 990FX SB950 ATX AM3+ USB3.0 RAID CrossfireX SLI Motherboard

The 990FXA-UD3 motherboard is designed to offer a stable, high-speed platform for delivering amazingly fast data transfer via the GIGABYTE 333 onboard acceleration technologies. Featuring the USB3.0 controller, AMD 900 series motherboards allow users to take advantage of super fast USB transfer rates of up to 5Gbps, delivering 10x faster data transfer compared to USB 2.0.

The AMD 900 series motherboards introduce a unique hardware design with lower resistance fuses for ensuring lower voltage drops and providing more stable and plentiful power delivery. All USB ports also benefit from a 3x power boost for better power delivery to power hungry USB devices.

(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) Whether the CPU/system fan speed control function is supported will depend on the CPU/system cooler you install.
(Note 5) Available functions in EasyTune may differ by motherboard model.

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 no longer offer support for Win9X/ME/2000/XP SP1/SP2. If drivers are available from the vendors, we will update them on the GIGABYTE website.
