DDR2 is overstretched beyond its Gigahertz limits?

THE ORIGINAL DDR memory was specified at 266MHz throughput and ended up at 400MHz officialy, with vendors like OCZ or Corsair going up to 600MHz in selected parts. Now, the DDR2 official spec is frozen at 800MHz, but there are plenty of parts running at 1066MHz and above for 'enthusiasts'. Now, in the famous press kit that Nvidia sent to the journalists on the Nforce 680i a month ago, for the first time, another new speed grade was mentioned - an 'upcoming version' of Corsair Dominator overclocker's memory, running at no less than PC9600, or DDR2-1200 throughput speed! And, there is even talk of extending the DDR2 spec to 1066MHz officially.

Realistically, you probably couldn't run that memory at this speed with anything less than 2.2 volts supply - far higher (and hotter) than the 1.8 volt specificiation of original DDR2 or the selected dies used on those DIMMs. In many cases, 2.3 volts are recommended, coming close to the old 2.5 volt DDR1 voltage levels. Are we going too far with DDR2, instead of early switching to the 1.5 volt DDR3 at the 1333MHz throughput?

Even with DDR3, my 2ns X1800's DDR3 loves the voltage. >2.4v nets a nice boost in overclockability. Those who don't want to tweak won't, what's the point of this article?

since there aren't any moving parts, up the voltage is fine with me. You have gates and transistors opening and closing, but it's not the same thing. If they give you warranty for it, fine by me!

The title of this article reeks of something awful. Like its from someone who has no idea what they're talking about, or even how to talk in general.

Who makes that decision? At what point does that decision get made?

Its about cost and supply. There is no big DDR3 supply and cost is very expensive compared to DDR2

It's actually about jacking up prices for little real world performance gain when existing tech gets too cheap. They need to sell new motherboards every six months, whether anyone, outside of the niche pro market or server market, really needs them or not.
