If you can change the batteries in your remote control, you can upgrade your memory too! It really is that simple!
The files and programmes on your device are stored on the Hard Drive or Solid State Drive, not the RAM - so you will not lose anything when replacing modules.
If you work from home or are thinking of doing so in the future you need to have the right tools available to do your job as efficiently as possible. Whether you use your own computer or a company owned device, do not be slowed down by insufficient memory or storage. Upgrading the memory and/or SSD is a simple way to save time when working from home.
Best online price for the RAM I wanted, branded memory modules, fast delivery, tools to easily locate compatible parts. Very smooth experience overall.

This is the most professional outfit I have come across.
They know their business inside and out.
Always a pleasure and stress-free to deal with.
You can order from them with the confidence in knowing you will get the right memory for your computer at a very acceptable price, coupled with a speedy delivery.
Can not express how good they are
Try them yourself
You will not be disappointed
