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.
