FYI, the Haswell memory controller seems to be signficantly better than the IB one. At least in my own experience.
I have been playing with the Samsung memory that was such a good value a year ago or so. This stuff: http://www.newegg.com/Product/Produc...82E16820147096
It always seemed like my sticks were a little under par. I couldn't get them stable at 1866 without running CAS10. and anything above 1866 was a definite no go without very high latencies. That was on my wife's IB machine. They were still a very good value, so I was still happy to run them at 1866 CAS10.
Fast forward to this week when I got my Haswell setup on the test bench. Same sticks are doing 2133 at 10-12-12 (1T) with Haswell. They wouldn't even run that speed at CAS 12 on my wife's IB. They passed my stress tests at those speeds (IBT, AIDA64), but I like margin and will run them at 2000 with the same timings and voltage.
Just giving people a heads up on this. Whatever your sticks were able to run on IB or SB, they may be able to run significantly higher (or lower latency, or both) on Haswell. While this may not translate to a ton of additional real-world overall performance, may as well take what you can get, right?
