Improve Performance With Kingston Memory. Kingston offers extremely reliable, high performance desktop memory and sells more laptop upgrade memory than anyone in the world. Add reliable Kingston memory and watch your productivity soar. Pages will load faster and launching new applications will be easier and faster. If your system is lagging, or a program doesn’t respond or won’t load, you may have a memory shortage. You may see subtle signs, like poor performance in everyday tasks, or you may be receiving “out of memory” messages. Laptop and PC manufacturers often include standard low-capacity memory modules to reduce cost, which means even new computers may need memory upgrades right out of the gate. Two options: Remove and replace these existing smaller capacity modules, or fill unoccupied memory slots. In case your memory fails, rest assured that Kingston can deliver what you need to get back up and running with our lifetime warranty.
