Just wondering about this ram I just bought at fry's for 159.99 (wrong price tagging ) It has 512mb winbond chips on it (3.3v), and the pcb is painted silver. It also has a life time warranty. Serial is w942508BH-6. I don't really know who made it, though there's printed marking on it that I believe are the Delta and Ohms symbols next to eachother.
