Thank you

That's a good questions, what chipset does HP Pavilion Desktop 590-p0xx have? I mean it's a 2019 PC, so for 2019 I would expect it to be at least 2nd gen chipset, as the 3rd one was out already... The cpu is 2nd gen APU 2200g amd - which has 12 pci-e lanes, which is not great, but just 8 goes to the 16x PCI-E - which I don't use anyway, since it's not used why not provide 4 lanes to the NVME? But it seems the chipset doesn't make any difference here, as the nvme is connected directly to the CPU via the PCI-E lanes.
