Setup and Installation
Before installing the graphics card, ensure your system meets the minimum requirements and is powered off and unplugged from the wall outlet.
System Requirements:
- PCI Express-compliant motherboard with one x16 graphics slot.
- Minimum 750W power supply with three 8-pin PCIe power connectors.
- Sufficient space within the PC case (Dimensions: 12.99 x 5.51 x 2.2 inches).
- Operating System: Windows 10 64-bit or later.
- Internet connection for driver installation.
Installation Steps:
- Prepare Your System: Power off your computer and unplug the power cord. Open the computer case.
- Locate PCIe Slot: Identify an available PCI Express x16 slot on your motherboard. Remove any expansion slot covers that block the slot.
- Install Graphics Card: Carefully align the graphics card with the PCIe slot and press it down firmly until it is securely seated. Ensure the retention clip on the motherboard clicks into place.
- Secure the Card: Use screws to secure the graphics card to the PC case at the expansion slot bracket.
- Connect Power: Connect three 8-pin PCIe power cables from your power supply to the corresponding power connectors on the graphics card. Ensure all connections are firm.
- Close Case and Connect Peripherals: Close your computer case. Reconnect all peripherals (monitor, keyboard, mouse, etc.) and the power cord.
- Install Drivers: Power on your computer. Once the operating system loads, download and install the latest AMD Radeon drivers from the official ASRock or AMD website.

Operating the Graphics Card
After successful installation and driver setup, your ASRock Radeon RX 6800 XT Taichi X graphics card is ready for use. This section covers basic operation and features.
Display Connectivity:
Connect your monitor(s) to the available display outputs on the graphics card. This model supports:
- 2 x DisplayPort 1.4 (with DSC)
- 1 x HDMI 2.1 VRR
- 1 x USB-C
Dual BIOS Functionality:
The card features a Dual BIOS switch, allowing you to select between two different BIOS profiles: P (Performance) BIOS and Q (Quiet) BIOS. The switch is located on the side of the card. Ensure the system is powered off before switching the BIOS.
- P (Performance) BIOS: Optimized for maximum clock speeds and performance.
- Q (Quiet) BIOS: Prioritizes lower fan speeds and quieter operation, potentially at slightly reduced performance.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your graphics card.
Cleaning:
- Regularly clean dust from the fans and heatsink using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Hold the fan blades gently to prevent them from spinning rapidly during cleaning, which can damage the bearings.
- Wipe the exterior of the card with a soft, dry, anti-static cloth.
Temperature Monitoring:
Monitor the GPU temperature using software utilities (e.g., AMD Radeon Software) to ensure it stays within safe operating limits, especially during heavy loads. The Taichi 3X cooling system is designed to manage thermals effectively.
