like i said im not a hardware engineer but im fairly certian that the tripple channel ram accounts for the slower speeds because there is another physical channel
something like 500x2=1000 and 400x3=1200
400 is less than 500 but if you have three channels your total is higher

We have seen today that dual channel memory on the Core i7 is more than enough to keep it fed with bandwidth, especially since the CPU and memory are communicating with each other directly. There is very little lost bandwidth and it makes better use of all of the dual channel memory than the triple channel memory. However, with Intel’s plans to increase speeds and allow heavier memory usage, especially with IGP based systems, the extra bandwidth will end up being welcomed.
Our moral to this story is if you’re planning on a Core i7 system, don’t just go out and buy triple channel memory straight away. If your budget allows for it, then by all means more memory will help, especially in Vista. However, with today’s results you can see that dual channel memory is more than capable of keeping up with the Core i7.
