PCIe 4.0 X16 Riser Cable for RTX3090 RX6800xt Graphics Cards ITX A4 PC Case PCIE4.0 16x Double Reverse Extension Flexible cable(R33UF-TU-BK-4.0)(21cm)

PCIe 4.0 has high requirements for equipment. There may be incompatibility with 4.0, and it needs to be reduced to 3.0.
As long as the extension cable is connected, the signal will be attenuated.
This product does not guarantee PCIE 4.0 full speed, the equipment is aging, the signal is poor or the environment is not good, please reduce the speed to use.

Adapted graphics card: RTX3090 RX6800xt, supports PCIE 4.0 graphics card
Speed bandwidth: PCIe 4.0 x16
Compatible chassis: A4 ITX custom chassis
Usage restrictions: Only for the installation and use of the ITX motherboard and its adapted mini case. To
Description of wire length and hole distance:
The length in the option refers to the length of the wire, excluding PCB and connectors. The length of the wire is marked with the red arrow in the figure below. Refer to the green arrow dimension for the screw hole pitch
There is metal shielding, advanced EMI shielding conductive polymer, new materials for EMI shielding, flat cable design.
This technology allows each cable to be completely covered by the electromagnetic interference shield of the conductive polymer,
To prevent the incidence or emission of electromagnetic frequencies,
Minimize interference and performance degradation, and reduce the weight of the cable.
The thickness of the black cable is 1.3 mm, and the thickness of the silver cable is 1.4 mm. The wire can be bent or folded without affecting the use.
Insufficient performance or abnormal function of the connected graphics card extension cable, common problems

1. The extension cord is incorrectly assembled. The graphics card extension cable should be installed in the graphics card slot closest to the CPU. Other slots have poor performance.

2. The golden finger of the graphics card or the socket terminals of the motherboard are in poor contact or there is oxide, which causes the graphics card to be slow. The golden finger contact points should be clean.

3. The motherboard is aging, the graphics card is aging, and it is not recommended to use an extension cord for devices more than 3 years old. Please use low speed if the equipment is aging or the signal is poor
