Any half decent 8GB memory kit makes up for the speed loss, yes. A half decent CHEAP 8GB memory kit would be able to handle 8-9-8 timings around 1.65v at 1866, but have no OC headroom. A half decent 8GB memory kit REASONABLY PRICED would be able to handle 8-9-8 around 1.65v at 1866, with enough OC headroom to touch 2000MHz @ either 8-9-8 or 9-9-9 timings depending. If you buy G.Skill Ripjaws, I'd put money on their CL7 1600 8GB kit doing 8-9-8 @ 1866 with 1.65v.
