Another site I asked this on I was told that I should get the first kit. One of the reasons was that "1866 also requires that the memory controller on the cpu be overclocked leading to more heat and voltage requirement."
Is this different than just setting the memory multiplier and timings? Does using 1866 RAM ( the third link) require doing something different than with 1600? Just curious.
Does it matter that two of the timings change but the others don't? I've seen charts that say low latency 1600 beats 1866 CAS 9 (except in bandwidth) but I don't know enough about each of the timing numbers. And how would the timings affect the bandwidth itself?
I'm mainly looking to (hopefully) get a bit better performance in a certain program that requires a lot of quick read/write to and from RAM. (I'm actually asking about this on their forum, too)
