Pitam se kako mi je do sada ovako nešto promaklo?
"There is hope for existing Ryzen systems, though.
AMD representatives confirmed that 300- and 400-series AM4 motherboards can support PCIe 4.0. AMD will not lock the out feature, instead it will be up to motherboard vendors to validate and qualify the faster standard on its motherboards on a case-by-case basis. Motherboard vendors that do support the feature will enable it through BIOS updates, but those updates will come at the discretion of the vendor.
Most older motherboards could support a PCIe 4.0 x16 connection to the first slot on the motherboard, but the remainder of the slots could revert to PCIe 3.0 signaling rates. That's because any trace routing on the motherboard that exceeds six inches requires newer redrivers and retimers that support PCIe 4.0's faster signaling rates. That means the PCIe slot nearest to the CPU will easily support PCIe 4.0, while the other slots, including M.2 ports, could run at PCIe 3.0. Support could be limited to slots based upon board, switch, and mux layouts."
