As I said, as someone who worked at Fry's, you have to be careful, they are shitty. Even with the hardware of computers (Components section, where I worked). Most of the RAM, processors, and boards are good if they are new, because they go directly to the cage. Anything used, though, is suspect as Hell. Usually doesn't get tested or anything. It's usually just thrown back in the box and re-sold. If not that, components on boards and stuff get messed up and touched all the time, because they don't get handled with gloves, or even care. Same holds true of RAM sticks.
You're better off going to Newegg or Amazon, because prices are better. Fry's even started price matching Amazon, because they know the shit is cheaper.
