Hi I am configuring a custom server right now and I am unsure whether I understand pcie correctly. Currently I am looking into adding a network card (specifically the Intel x520-da2) which is a pcie 2.0 x8 card. But my Mainboard only supports pcie 3.0 x4. If I understand the compatibility with pice correctly I should still get the full bandwidth of the dual 10Gbps right?
it will run at 2.0x4 which should be plenty fast for two 10Gbps ports as it should still do 2GB/s
tho there are always a chance of weird hardware incompatibilities, soo google you motherboard and the nic
