That's a surface mount component (resister or capacitor) that has been dislodged from its proper position. Personally, I wouldn't use, or even try to fix this as there's no telling what else might be wrong with it. Return it.
I am no RAM expert, but I would say that that is a small cosmetic defect that will have no effect on the functioning of the RAM and will not be noticeable when the RAM is properly installed. I would not worry about it.
