All on Amazon. But what I can't tell is what the hardware/feature difference is between these specific revisions, the B,D and Z. Are they identical? Is it the release/build date? For my mobo does it matter which one I get?

Hi, I am finding a slight price difference between these revisions of the same RAM. What's the difference? I can't find any specific information on these revisions and why the prices would be different.
