There are several versions of Micron D9's listed in the link.
What do you mean by "fatbody?"
Also, I note that only a few models use Aeneon chips, but I had a very good experience with Aeneons in the OCZ Platinum DDR400 (2,3,2,5) kits.
Some reviews tout A-Data as among a few of best-performers (as I recall . . ) I see the Aeneons in one Mushkin model and some OCZ Gold GX-ers. IF (and only if) the lower-speed DDR2 models with Aeneon behave like the DDR Platinums I mentioned, you would think that they would be extremely over-clockable at the rated latencies and modest voltage increases.
