I would like to increase my RAM potencial in my ASUS Rampage Extreme. For now i have 8 GB 1333 from Crucial, and it works just fine. I can't go to the lower latencies keeping my system stabile. I was curious, whether four stick of Corsair CMP8GX3M4A1600C8 would run on my system at all. So I could lower its speed for gaining short latencies.
the performance gains from lowering latencies is 1 or 2%. unless you actually need more than 8GB of ram dont bother with getting another kit or replacing them all together.
if you want more performance you can overclock your cpu or your gpu.
