    In fact, you have two m.2 slots on that motherboard from the illustration on the Asus product page. At least one should be PCIe 4.0.
    Hi Dennis

    I found the online schematic drawing of
    ASUS PRIME X570-P motherboard
    https://gzhls.at/blob/ldb/0/6/1/6/4e...7a4563734b.pdf

    How can I mount the 2TB NVME pcie 4.0 SSD on the PCIe 4.0 slots ? Pls see attached screenshots

    Thanks

    Just found following YouTube video;
    How to install Samsung 950 PRO M.2 SSD in a PCIe slot with a Lycom DT-120 M.2 to PCIe adapter
    https://www.youtube.com/watch?v=LDRm0Y8pNMo

    I have to buy a Lycom DT-120 M.2 to PCIe adapter

    Re: Specification of new NVMe SSD to be purchased.

    If you have two M.2 slots, why would you need an adapter?
    I think that is only for those with one slot on motherboard.

    11 is M.2 Socket 3. Is it for pcie 3.0 ?

    Pls see attached screenshots

    I found it. Pls refers to attached screenshot - screenshot_socket3_55.png

    For 3rd Gen AMD Ryzen™ Processors, the M.2_1 socket supports PCIe 4.0 x4 mode
    and SATA mode M Key design and type 2242 / 2260 / 2280 storage devices.
    • For 2nd Gen AMD Ryzen™/2nd and 1st Gen AMD Ryzen™ with Radeon™ Vega
    Graphics Processors, the M.2_1 socket supports PCIe 3.0 x4 mode and SATA mode
    M Key design and type 2242 / 2260 / 2280 storage devices.
    • The M.2_2 socket supports PCIe 4.0 x4 mode and SATA mode M Key design and
    type 2242 / 2260 / 2280 / 22110 storage devices.

    To my understanding both M.2_1 and M.2_2 sockets support PCIe 4.0 x4 mode

    Well, M.2_1 could be PCIe 3.0x4 or 4.0x4 depending on the processor you are using. If its 3rd generation processor, then it's PCIe 4.0. Otherwise, it's PCIe 3.0.

    The other socket M.2_2 is PCIe 4.0x4 for all the mentioned processors.

    That's how I interpret what it says.

    1)
    According to my CPU spec.
    Whether I can use socket M.2_1 for PCIe 4.0x4 without loss in speed ?

    2)
    I can use socket M.2_2 for PCIe 4.0x4 without loss in speed, disregarding CPU ?

    Thanks

    I'm not familiar with the AMD processors - all of mine are Intel. So you have to determine whether yours is considered 3rd generation. It might be so because of the 3XXX numbering. I'm not going to guess on that. Ask in a separate thread if you are not sure and can't figure it out by searching. Someone will know.

    If it's determined to be 3rd generation, then the answer to (1) would be yes and (2) would be yes. If it's not 3rd generation, then the answer to (1) is no - the PCIe 4.0 drive would function at PCIe 3.0 speed; and the answer for (2) is yes - the 4.0 drive would work at full 4.0 speed. Page I-19 in the user manual sets no restrictions on the M.2_2 slot based on the CPU.

    Follow up: I googled on the drive model shown in your post number 15. Is this your processor described here?
    https://www.amd.com/en/products/apu/amd-ryzen-5-3400g
    If so, the box in the top illustration says "2nd generation"
    That would mean an NVMe PCE 4.0 x 4 drive would need to be in the M.2_2 slot to function at 4.0 speed. That should not pose a problem - you only will have one PCIe 4.0 drive.

    Yes.

    Thanks for your information

    A side question.
    ==============


    I'm prepared purchasing;
    Samsung 2TB 980 PRO M.2 2280 MZ-V8P2T0BW PCIe Gen 4.0 x4, NVMe 1.3c SSD

    and connect it in M.2_2 slot

    Which will be an easy and reliable way to migrate/dump all files from my old Intel 1TB PCIe Gen 3.0 x4 NVMe SSD

    to it?

    Thanks

    Regards

    Do you mean cloning (making an exact copy)? I've never needed (or wanted) to do that, so I'm not qualified to advise. I suggest making a new thread with that question.
