Upgrading the memory (RAM) on your PC is usually rated the single most effective way of improving your PC’s performance. However it’s a challenge knowing what memory to buy and going to the PC manufacturer’s website isn’t necessarily the easiest or most cost effective way to find it. Crucial.com provides a simple tool to identify what memory your PC already has and what the options are to upgrade. Having identified what you need, you can see the cost and then place an order if you want to proceed. I’ve used Crucial several times with excellent results.
