Hi mate

If you have all 4x slots populated the bandwidth will drop down to 8x on all slots OK no matter that slots 2 and 4 will only use 1x.

If you have say SLOT1 with a GPU and you plug in a raid card and sound card say in slot3 and 4 you will still get full 16x bandwidth in slot1 for the GPU, it will not drop to 8x
