At that rate a riser stops being a cable and becomes a transmission line: crosstalk and loss decide whether the link trains at Gen4 or quietly falls back. This one uses aluminium-foil-shielded differential pairs to keep the pairs isolated, which is what makes a run of this length viable at full Gen4 rather than Gen3.\u003c\/p\u003e\n\u003cdiv class=\"rtx-note\"\u003ePractical note: 40 cm is a long run for a passive Gen4 riser. On most boards it trains at Gen4 without complaint. If yours is marginal — a heavily loaded platform, or a slot fed through a switch — you can pin the slot to Gen3 in BIOS and keep full stability with no other change.
