The Noctua website says these two items are compatible but when the ram is in slot a1 and b1 the pipes on the cooler go right through the side of the ram in slot b1. So if I slot the ram in a2 and b2 it seems to fit but then I believe I forfeit dual channel mode? Also when all the brackets are on the I can not screw down the spring loaded screws one side always pops off if I use a little pressure to force it down.
