Why does it matter? It's only the ICs that are good, and the tuning done by chew*. If you are really interested in what they are, my bet is on Corsair Dominator GT, 2 sticks of a triple channel kit, look at the SPD, 7-8-7-20 timings at rated speed, so most likely the 1000MHz kit.

Thanks for the thread chew*, I wonder who is sending all those PMs to you...
