Right now, i have 1 stick of 512mb kingston hyperx pc3000 in my pc and i want to add another stick in, only the problem is pc3000 is kinda hard to find, and rather expensive. So i was wondering if i could put in a stick of, oh lets say pc3200 (still kingston hyperx) and would it still work in dual channel? Im assuming no, but it never hurts to make sure. Also, if anyone knows of a place that sells pc3000, link plz!
