  1. *To reach DDR3 2200 MHz and above, you are required to use with Intel Core i7/Core i5 CPU without HD Graphics and install a discrete graphics card.
  2. When using Intel Core i5/Core i3/ Pentium CPU with HD Graphics, the maximum memory speed supported is 1666 MHz
  3. 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.
  4. To use the onboard D-Sub, DVI-D and HDMI ports, you must install an Intel CPU with integrated graphics.
  5. The DVI-D port does not support D-Sub connection by adapter.
  6. You can use only one of the onboard digital graphics ports (e.g. HDMI and DVI-D) for output when in the BIOS Setup program or when during the POST screens.
  7. For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
  8. The PCIEX16 slot operates at up to x4 mode when ATI CrossFireX™ is enabled.
  9. Whether the CPU/system fan speed control function is supported will depend on the CPU/system cooler you install.
  10. Available functions in EasyTune may differ by motherboard model.
  1. Most hardware/software vendors may no longer offer drivers to support Win9X/ME/2000/XP. If drivers are available from the vendors, we will update them on the GIGABYTE website.
  2. Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website.
