are you overclocking the CPU or just running stock?

running at stock

you should just have to adjust the CPU : DRAM ratio & of course ensure that yor DRAM voltage is at what Corsair recommend for that speed.
Tbh you probably won't see any difference in performance between higher speed but higher latencies as well & lower speed/latencies except in some synthetic tests.
