My PCIe slots aren't running at their normal bandwidths of 16x/4x. Instead they are running at x4/x8(according to GPU-Z). The board is advertised to run at 8x/8x, which I now know was a lie according to all 870 board specs, but is supposed to run at 16x/4x. I never checked their bandwidths untill now so they could have been these speeds the whole time. My question is, is this normal? Is there something to fix it and put it back to its proper speeds? Can provide GPU-Z pics if needed.
