OCZ just started sampling what might be the fastest DDR3 1333 to date. It has 2x512 MB kit that will start selling in a few weeks at CL 7-7-7-20. DDR3 1333 usually works at CL9 so this one might be the one with the lowest latencies around.

We expect this memory in our lab shortly and let’s see what we can do about it, but we are certain that it can go even higher than 1333.
