NO! There is no problem with the KT266A, the problem is with the KT266. They mass produced them so quick and they are now overstocked and still trying to get rid of them. As soon as inventory goes down then the manufacturer's will start pumping sales with the KT266A. Why do you think the big makers haven't come out with the KT266A mobo yet? Because they are loaded with the previous model. The time span between these two chipsets was so close it caught makers by surprise!
