I have a Gigabyte h97-d3h https://www.gigabyte.com/Motherboard/GA-H97-D3H-rev-10#sp and found the hard way that the m.2 on board slot, runs only at pcie 2.0 x2 speed bottlenecking my Samsung PM981. Question is now if I buy a Pcie adapter card, do I still have enough pci lanes for it to run at x4? I only have 1 pcie 3.0 x16 slot, the other is pcie 2.0 x4 from what the specs state. Am I doomed? Don't have money to buy a new motherboard, cpu and ram

  1. 1 x PCI Express x16 slot, running at x16 (PCIEX16)
    (The PCIEX16 slot conforms to PCI Express 3.0 standard.)
    * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
  2. 1 x PCI Express x16 slot, running at x4 (PCIEX4)
    • The PCIEX4 slot shares bandwidth with all PCI Express x1 slots. All PCI Express x1 slots will become unavailable when a PCIe x4 expansion card is installed.
    • When installing a x8 or above card in the PCIEX4 slot, make sure to set PCIE Slot Configuration in BIOS Setup to x4. (Refer to Chapter 2, "BIOS Setup," "Peripherals," for more information.)
  3. 2 x PCI Express x1 slots
    (The PCIEX4 and the PCI Express x1 slots conform to PCI Express 2.0 standard.)
  4. 3 x PCI slots
  5. 1 x M.2 PCIe connector
    (Socket 3, M key, type 2242/2260/2280 SATA & PCIe SSD support)
  6. 1 x SATA Express connector
  7. 6 x SATA 6Gb/s connectors
    (M.2, SATA Express, and SATA3 4/5 connectors can only be used one at a time. The SATA3 4/5 connectors will become unavailable when an M.2 SSD is installed.)

The adapter goes in the PCIe 2.0 x4 slot.
That I know, my question was about bandwidth. Since it's not pcie 3.0, isn't the pcie 2.0 x4 the equivalent of the integrated m.2 slot on my motherboard? So would an adapter be an option to get more speed or would it be just a waste of money if it will have the same speed as the m.2 slot which is already there?
