    I don't have a great deal of insight into this story but it seems like there might be firmware issues with the PWM on the UD3, UD5 and the Assassin 2. If this is a quality issue or not is of course hard to say, but I remember reading something about there being suspicions of bad quality PWM components also playing a role in this. Anyway, I trust International Rectifier's products (which I believe they use on the UD3, UD5 and Assassin 2?), whether it's the new IR digital PWM or the IR MOSFETs. And I'm convinced Gigabyte will be able to continue using them and that this'll be sorted soon without much of a hassle.

    By the way, I find it strange that the UD7 is seemingly unaffected by all this. Doesn't the UD7 use mostly the same digital PWM/components for the VRM as the other boards? Probably not as that would be expensive! :o
