No display or show bad performance on GPU holder/Riser cable

When you are experiencing no display or bad performance from a GPU holder/riser, it may indicate several potential issues. Follow the steps below to troubleshoot and identify the cause of the problem.

1. Verify PCI-Express Configuration
   1. Check your motherboard's user manual or BIOS settings to ensure that the PCI-Express configuration is set to the appropriate generation (Gen3 or Gen4) for your GPU. Incorrect settings can lead to compatibility issues and poor performance.
2. Check Connections
   1. Make sure that the Riser cable connecting your GPU to the PCIe slot on the motherboard is securely plugged.
   2. Check the GPU itself and ensure that it is properly seated in its PCI-e slot on the riser. Verify that it is firmly and correctly connected.
3. Inspect Cables and Slots
   1. Examine the PCI-e cable for any signs of damage, such as missing or damaged pins. If you find any issues, try to plug the GPU directly into the motherboard to rule out cable-related problems.
   2. Carefully inspect the PCI-e slot on the motherboard and the slot on the riser for any physical damage, missing pins, or foreign objects. Clean any dirt or debris from the slots using compressed air or a soft brush.
4. Address Power Delivery Issues
   1. If you have access to another functioning GPU, try installing it on the riser to determine if the problem is specific to the GPU itself. If the second GPU works fine, it indicates that the original GPU may be faulty
   2. If the second GPU also exhibits no display or poor performance, it suggests that the issue lies with the riser or other components in the system

Remember to exercise caution and handle components gently while troubleshooting to avoid causing additional damage.
