One thing that may contribute to low demand is how Motherboard manufacturers limit the max memory now that a Windows 64bit OS holds more or less 50% of the market.
Give us more slots and raise the memory max for cheaper motherboards. They don't advertise the benefits of having more memory... The free lunch is over - Tech people are buying up ram, but that is not enough since you are floading the market. We cannot keep up. I'm still on DDR2 and I have several machines. Only if I buy something new will I be upgrading. You got to advertise to the mainstream. Intel is doing it with their processors... educate people about memory. And make it less confusing.
I have my eye on the Corsair Vengeance 16GB LP DDR3-1600 kit for my next upgrade. I'm hoping for some more price drops in their excellent line although the prices at present are already very reasonable.
