Improve Performance With Kingston's DDR4 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.
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 and model number with our memory finder, and we will provide detailed information on the best memory configuration to achieve the best performance for your system.

Easy ordering, quick delivery
Great service, would use again
Tried to find the guide to identifying the type of RAM I required for my PC. Couldn't find it, but used the "Chat" facility, and it was very helpful in providing the part no I required. I ordered it and fitted the other day. All is well.
Works perfectly in the J10. Thank you Kingston.
Very good communication love the way they check for compatibility with the device the memory is going in to reduce returnees and gives me price of mind that I have ordered the right one
Fast, efficient service. I raised a query about pricing and this was dealt with quickly. Happy buyer!
