Difference between E4 and E6 stepping for Socket 939 Athlon 64 x2 4200 CPU. Which one to get?

[EDIT]

I just checked AMD's website and the BV is an E4 and the CD is an E6. So which one to get? Does one of the steppings overclock better than the other? Does one handle 4 x 512 RAM better than the other?

What's the difference between these two Athlon 4200's? One is a A64-42BV the other is a A64-42CD and they're almost the exact same price? One is an E4 stepping? Which one would you get?

I owned the E4 core for about a year and it was super stable at stock and ran cool. I did a mild overclock and pushed it to 2.5 w/ no problems either. However, I don't know how it compares to the E6.

e6 is the newer stepping, you'll probably do much better with it.
