1. The sticker is on RAM the person is INSTALLING, not the installed RAM (as the previous poster already said). 2. The sticker refers to ITSELF, not the RAM module. I've seen it on numerous third-party computer components, including RAM and hard drives. It contains information on the date and location of manufacture, and the manufacturer of the part needs that information to track consumer-discovered flaws. Were Apple to put a removal notice for the RAM component itself, it would attach to both the RAM stick and the motherboard, so that removal would be evident. 3. Apple specifically states that HD and RAM upgrades may be done by consumers without violating warranty.
