Hey, I want to get some DDR3-2200 RAM, but I noticed that the i7's say "DDR3-1066/1333" for their memory type (like here). If I bought DDR3-2200 would it be any better than DDR3-1333? I also see that the latency takes more clocks on DDR3-2200 anyways, so is it really much faster?
You would only see a performance gain if you did some extreme overclocking to get it to 2200 I would just get a set of triple-channel 1600's if I were you they are good enough for normal overclocking.
