The ONLY way to know for sure is to remove the heat spreaders and look at the ICs. This has been stated many times in this thread and has not changed.

Which of the ICs listed above are considered the best for overclocking? I've head people say that the Micron D9s are the business, but that the Elpida Hypers are also good.

Also, why use so many different kinds? Does it come down to stock availability at IC suppliers? I mean, the price of a kit is determined by the product range / code, not by the kind of IC used, correct? I suppose the cheaper / weaker ICs are used more in entry level RAM sticks / kits.

From what I hear it's determined by what's popular and/or in stock at any given time.

Nothing to do with popularity. Totally about what's available to build the sticks at the time. The price isn't based upon which manufacturer's IC they use. However, the IC market changes daily which in turn changes memory prices quite often.

I know it's been said before that the only available information is in the first post, and there's no way to find out more other than to remove the heatsinks.

But I'm curious to know what the second decimal represents.
The first decimal I assume is the IC size, 1 for 256Mx8, 2 for 512Mx8 and only one decimal for 128Mx8. But what about the second decimal? There's got to be a reason for it and somebody surely knows it.
