1. To experience Window 8 fast boot function, the firmware of motherboard must support UEFI with fast boot set up ready. For further details, please refer to the motherboard manufacturer’s instruction guide manual.

2. Only supports window 8 64bits operating system with UEFI boot mode installed.

3. Motherboard firmware is suggested to be updated with latest Window 8 UEFI compatible mode.

1. 如果想体验Windows 8快速启动功能，主板固件必须具备支持UEFI快速启动设置。有关进一步详情，请参阅各主板厂商的用户指南手册。

2.只支持UEFI引导模式进行Windows 8 64位操作系统的安装。

3.建议将主板固件（BIOS）更新为最新的Windows 8 UEFI兼容模式。

对于搭配一些声称可以支持UEFI功能，但主板BIOS却又未能真正支持UEFI的主板，有可能会存在开机无显示的问题。
若主板无法启动时, 即代表主板是不能支持UEFI。请把主板上的UEFI设置为关闭模式, 再重新启动。

For the no boot issue, it is happened in some motherboards that claimed support UEFI but their motherboard bios is not good enough to support the true UEFI. If your motherboard does not work, it means it cannot support the UEFI. Please set the motherboard with legacy mode only and restart.

1. 清洁主板的PCI-E插槽以及显卡的金手指部分

2. 检测外接电源线是否连接好

3. 使用其它输出接口（例如：VGA/DP/HDMI/DVI等）检测是否同一现象

4. 检测显示器输入源或主板BIOS设置是否正确，例如：优先显示项或主板PCI-E GEN2或GEN3的等关联设置

5. 更新主板BIOS

6. 将显卡安装于其它正常平台上验证是否存在兼容性问题

1. Clean the graphics card's golden finger and motherboard's PCI-E slot

2. Check the power connector if it is well-connected

3. Check another interface (output port). For example, VGA or DisplayPort or HDMI or DVI etc.

4. Check the input source in monitor's menu or BIOS setting if correct. For example, Priority display option or PCI-E GEN2/3 etc.

5. Upgrade the motherboard's bios to the latest version

6. Install the graphics card in another PC to confirm if the graphics card is compatible with your current motherboard.

For the no boot issue, it is happened in some motherboards that claimed support UEFI but their motherboard bios is not good enough to support the true UEFI. If the motherboard manufacturers released the bios to support the UEFI, we just need to ask the user to use update their motherboard bios. However, some motherboard manufacturers didn't release the bios to support the UEFI. We only can ask the user to set the motherboard to boot with legacy only.

Restriction for Window 8 fast Boot

1)    To experience Window 8 fast boot function, the firmware of  motherboard must support UEFI with fast boot set up ready. For further details, please refer to the motherboard manufacturers instruction guide manual.

There are some reports that 7770 and 7750 in CrossFire mode may have performance issue with AMD Catalyst 13.4.
We would recommend you to use AMD Catalyst 13.1 for HIS 7770 & 7750 in CrossFire mode.

The normal temperature would be under 100 degree Celsius (°C).
Normally if it still work, the temperature would be acceptable.

当运行交叉火力时，显卡需要同一系列，如7900与7900，7800与7800.
