I don't know what chips those sticks use, and the site that used to keep
a database of the chips (commonly but not ALWAYS) used in certain model
DIMMs didn't work the last few times I tried it.
The important thing for you to know is Micron makes like a DOZEN different
models of RAM chip in their D9 series...
D9HNH,
D9HNL,
...
etc. etc. etc.
They have radically different speeds / performance / timings / etc.
Usually Micron does in general make good quality memory, so I'd have
little problem suggesting any Micron D9 series memory chips on a
reputable / quality DIMM manufacturer's product.
However the REASON you'd really want a certain D9 series chip on a DIMM is
really because that PARTICULAR model of D9 chip overclocks especially well,
so you'd really need to check the reports on that exact D9xxx model chip
to see how well it overclocks at what timings / voltages.
A quick search turned up among the following:

Folks purchasing RAMs might like to know...
Micron just got back to me about their superior D9s' serials.
These are the only industry "native" 1066MHz that's capable of performing at the standard JEDEC 1.8v with all the signal margins intact. It's based on 78nm process instead of the usual 95nm fabrication.
D9HCD MT47H64M8B6-25 : D
D9GKX MT47H64M8B6-25E : D
D9GMH MT47H64M8B6-3 : D
These DRAMs with a good PCB have the best chance to reach 1333MHz with higher voltage.
As far as i know these are the best DRAMs there is for now.
It is possible in the near future some DDR2's D9s will be based on Micron's recently introduced 65nm.
As to where they are being used? Folks at Crucial is looking things up.

Personal experience with D9GMH has been pretty good, 1000MHz 5-5-5-15 stable, 960MHz 4-4-4-12 stable also, and this weekend I'm going to try and tweak them a bit more, my goal is to see 1000MHz Cas4, but we'll see if that is possible without ramping the voltage too much.
Would be interesting to see how the 65nm compare to 78nm overclocking.

Bindi is right, there are many module makers like Corsair that changes DRAMs so often on a single model... it is hard to say what is what without removing the butter-spreaders.
I can't exactly see Crucial using Nanya, Promos or Infineon. Elpida maybe, due to special features on the Japanese DRAMs.

Crucial is owned by Micron, so they aren't likely to use anything other then Micron. I haven't heard of any of the Ballistix line not using Micron D9G chips. Corsair sucks when it comes to chips, as they change up so often, you are never really guaranteed Micron D9s from them unless you buy the really highend stuff.
