Does anyone know what is the difference between f2-6400phu1-1gbhz and f2-6400phu2-2gbhz from g-skill? I thought I bought the latter from newegg but in cpuz I see that my memory id is former. I emailed the tech from g-skill but they said it is same and 2 of f2-6400phu1-1gbhz modules makes f2-6400phu2-2gbhz. But I have seen thru out some forum on internet that people have f2-6400phu2-2gbhz as memory in cpuz. I am confused. Thanks for any inputs.
