PCI-E X1 or X16 must be it is V2.0 version, PCI-E V1.0 speed will not exceed 250M, we suggest directly inserted On the X16 slot, the pci-e x16 usually is v2.0 3. BOIS setting of the motherboard: Sata mode should be changed to AHCI, although some motherboard PCIE is version 2.0, but BOIS does not enable high-speed transmission mode by default (gen2 high speed mode) needs to be manually turned on.
