Key Features
- High-Speed Data Transmission: Supports PCIe 4.0 x16 for optimal performance with compatible motherboards and graphics cards.
- Flexible Design: 220mm length with a flexible ribbon design allows for folding and twisting without impacting signal reliability or performance.
- EMI Shielding: Incorporates comprehensive EMI shielding to prevent electromagnetic interference and maintain signal integrity.
- Strengthened Connection Protection: Enhanced durability at connector points to minimize signal loss.
- Versatile Installation: Ideal for various graphics card installation orientations, including vertical mounts.
Setup and Installation
Proper installation of the SilverStone RC05 riser cable is crucial for stable system operation and optimal performance. Follow these steps carefully:
- Prepare Your System:
- Power off your computer completely and unplug it from the power outlet.
- Open your computer case to access the motherboard and PCIe slots.
- Ensure you are working in a static-free environment or use an anti-static wrist strap.
- Identify PCIe Slots:
Locate the primary PCIe x16 slot on your motherboard where the graphics card would normally be installed. Also, identify the desired mounting location for your graphics card within the chassis.

- Connect to Motherboard:
Carefully insert the male end of the RC05 riser cable into the PCIe x16 slot on your motherboard. Ensure it is fully seated and the retention clip (if present on your motherboard slot) is engaged.
- Connect to Graphics Card:
Take your graphics card and carefully insert it into the female PCIe x16 slot on the other end of the RC05 riser cable. Ensure it is fully seated. If a protective cover is present on the female connector, remove it before insertion.

- Secure Components:
Once both ends are connected, carefully route the flexible cable to the desired position for your graphics card. Secure the graphics card in its new mounting location within the chassis using appropriate screws or retention mechanisms. Ensure the cable is not sharply bent or under excessive tension.

- Power On and Test:
Close your computer case, reconnect the power cable, and power on your system. Verify that the graphics card is detected and functioning correctly in your operating system.
Important Note: For systems with PCIe 3.0 motherboards, it is recommended to manually set the PCIe slot speed to Gen3 in the motherboard's BIOS/UEFI settings before installing a PCIe 4.0 riser cable to ensure compatibility and stability. While the RC05 is designed for PCIe 4.0, some older motherboards may require this adjustment for proper operation with riser cables.
Operation
The SilverStone RC05 PCIe riser cable is a passive component designed to extend a PCIe connection. Once correctly installed, it operates transparently, allowing your graphics card or other PCIe expansion card to communicate with the motherboard as if it were directly plugged in. No additional software or drivers are required for the cable itself.

Maintenance
The SilverStone RC05 riser cable requires minimal maintenance. To ensure longevity and optimal performance:
- Keep Clean: Periodically inspect the cable and connectors for dust accumulation. Use compressed air to gently clean any dust.
- Avoid Stress: Do not excessively bend, twist, or pull on the cable, especially near the connectors. While flexible, extreme stress can damage internal wiring.
- Secure Connections: Ensure both ends of the cable remain firmly seated in their respective slots. Loose connections can lead to intermittent issues or performance degradation.
- Environmental Conditions: Operate the cable within standard computer operating temperatures and humidity levels.
Troubleshooting
If you encounter issues after installing the RC05 riser cable, consider the following troubleshooting steps:
- No Display/System Not Booting:
- Ensure the riser cable and graphics card are fully seated in their slots.
- Verify that all necessary power cables are connected to the graphics card.
- If your motherboard is PCIe 3.0, try setting the PCIe slot speed to Gen3 in the BIOS/UEFI.
- Test the graphics card by plugging it directly into the motherboard's PCIe slot to rule out a card issue.
- Reduced Performance:
- Confirm that your motherboard and graphics card both support PCIe 4.0 for optimal speed.
- Check BIOS/UEFI settings to ensure the PCIe slot is configured for PCIe 4.0 (if supported by all components).
- Ensure the cable is not excessively bent or kinked, which could affect signal integrity.
- Intermittent Issues/Crashes:
- Reseat the riser cable and graphics card.
- Check for any physical damage to the cable or connectors.
- Ensure proper airflow within the case to prevent overheating of components.
