Gigabyte GA-990XA-UD3 AMD 990X Socket AM3/AM3+ SATA 6Gb/s USB 3.0 DDR3 ATX Motherboard - GA-990XA-UD3

GA-990XA-UD3 - The 990XA-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. Utilizing the industry's first Serial ATA Revision 3.0 solution via AMD SB950 chipset, GIGABYTE AMD 900 series motherboards offer native 6 ports of next generation high speed data storage devices support with data transfer speeds of up to 6 Gbps with RAID 0, 1, 5, 10. 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   
  (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.
  
  Remark   
     1. Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website.
     2. 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.
