Compare PCIe lanes on CPU and motherboard for performance needs.
Compare PCIe lanes on CPU and motherboard for performance needs.
I believe you're grasping the idea, but I appreciate your desire for confirmation. Let's review this together. The ASRock X570m Pro4 supports up to 36 PCIe lanes according to its specs. The 3600 model offers 16 PCIe lanes. If you connect the M.2 card using the 16 lanes available on the CPU, and the video card and onboard M.2 slot are also utilizing those lanes, you'd be using a total of 36. That means the numbers align correctly, not just by chance. Your setup seems to match the advertised capacity without any discrepancies.
The total count or number of lanes isn't important; focus on the available features, slots, and any instructions in the manual regarding which functions are disabled while others remain active.
Ensure your X16 card is plugged into the highest available X16 port, typically the one directly connected to the CPU. The next port is often reserved for X4 and should only be used for display output, not high bandwidth tasks. For M.2 slots, you can use any slot if routed through the chipset; however, AMD CPUs provide dedicated lanes for M.2 from the CPU, usually the top slot, so it won’t interfere with your X16 card.
Additionally, this hyper M.2 card needs a motherboard with PCIe bifurcation support, a feature available on some ASUS models but not all manufacturers offer it on ATX boards. This particular board appears to handle it.
