What is the difference between all the Corsair Xms 3200s?

Is it just the heatsinks that is differentiating the pricing between these?

Some people say that the chips used on the black heat spreader are different from the Platinum ones as they argue the Platinum ones are actually a version 1.1. I have yet to confirm this as there is no available spec sheet data on the different chips they use (at least none that I can find). However, if you look at the search link I provided, a rep from Corsair said that the only difference was the color, so who knows ;).

I just received a 256 meg stick of the XMS PC3200 C2 rev.1.1
and it has a black heat spreader. This came from newegg.com
