    What version of PCI express are you trying to extend? The environment you need to extend through makes a huge difference too, particularly with unshielded extenders.

  • @DavidSchwartz In my case it is PCIe 3.0 but the other versions might be also interesting for other people looking here.

    This appears to be a fly by night product operating outside of the pci express specifications. Going by the specs you need a signal retimer chip on each end and a much different looking cable that can be 1 meter long iirc. That is with copper of course. There are fiber solutions that can be much, much longer.

The maximum length for PCIe cable (all lane sizes) generation wise are as follows:



PCIe Gen 1: 15 inches.



PCIe Gen 2: 12 inches.



PCIe Gen 3: 8 inches.

    This looks like a cheap (unshielded riser) and the answer with the short lengths is probably true.
    On the other hand, watch this video https://www.youtube.com/watch?v=q5xvwPa3r7M



    With good risers Linus achieved over 3m extension.

      Linus achieves a lot of things. That doesn't mean it'll work with your particular motherboard and your other device. I wouldn't depend on it for anything where you need a reliable solution.

    • Yes, that's usually true. But in this case he just used the more expensive Thermaltake PCIe Extender. Nothing else. No special modifications. Ofc it's probably outside the official specs and you have to read the reviews of this item. And ofc I don't see a real need to extend PCIe even more than 30cm ...
