Cable length Description:

The length of the wire refers to the part of the visible wire. It does not include the PCB and the connector. For the wire length, please refer to the blue arrow in the figure below.

Product advantages:

1. The product uses high-speed shielded transmission line, high frequency supports PCIe 4.0 X16 stable transmission.

2. Unique individual laneway shielding prevents external EMI/EFI and interference between channels. Sectional design allows air ventilation and lowers working temperatures for better overall system performance.

3. Re-engineered wires and connectors suitable for PCIe 4.0. Quality hand soldered gold-plated contacts for signal integrity.

4.Designed with heavy-duty junctions at PCB/cable junctions for improved durability.


Since many PC chassis currently on the market come with PCIe riser cables and extenders validated only for PCIe Gen 3.0 operation, there may be some system stability issues when used in combination with PCIe Gen 4.0 devices. If you are experiencing stability issues such as choppy mouse movement, BSOD or hangs, please follow the troubleshooting recommendations below to pinpoint the problem:

1. Change PCIe Slot Configuration setting – The PCIe Slot Configuration option is found in the system BIOS. Change its current setting to Gen 3.0 then save and exit the BIOS. After the system reboots check whether the stability issues persist.
NOTE! For more information about your system BIOS and settings, please refer to the system/motherboard user manual.

2. Reseat devices – For example, remove the riser cable and extender and install the PCIe Gen 4.0 graphics card directly to the PCIe x16 slot on the motherboard. Ensure that the PCIe slot configuration option is set to Gen 4.0 (or Auto) then check whether the stability issues persist.
NOTE! Apply this step to any Gen 4.0 devices on your system connected by riser cables and extenders.

If either troubleshooting step resolves your system stability issues, it indicates that the riser cable and extender may not be PCIe Gen 4.0 compliant or potentially malfunctioning if it was not validated by the vendor.

The ideal solution in this case would be to replace the faulty riser cable and extender with one that is PCIe Gen 4.0 compliant and validated for compatibility with your PCIe Gen 4.0 device. If this is not currently feasible, then consider keeping the devices connected directly to the motherboard. However, if direct device connection is not appealing for any reason, you may consider setting the PCIe Slot Configuration option in the BIOS to Gen 3.0, as a workaround.
