Improve Performance With Kingston Memory. Kingston offers extremely reliable, high performance desktop memory & sells more laptop upgrade memory than anyone in the world. Add reliable Kingston memory & watch your productivity soar. Pages will load faster & launching new applications will be easier & 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 & 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 & 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 & running with our lifetime warranty. In some cases, memory modules of the same capacity must be installed in pairs to get the best performance from your system. Search for your system by name & model number with our memory finder, & we will provide detailed information on the best memory configuration to achieve the best performance for your system.
