When Would I Use a DDR3 CPU

To start off, if you want your computer to work seamlessly with gaming and other application, you need a proper RAM. It doesn’t really matter what kind of a processor you have if you don’t have an adequate RAM to support it. 

It Covers a Huge Range

The DDR3 RAM may have been surpassed by DDR4, but that didn’t happen till 2016 when the systems finally caught up with the DDR4. So, it means that many systems still operate on DDR3. The DDR3 RAM is compatible with a variety of range of CPU generations. These include Intel’s LGA1366 socket to LGA1151, AMD’s AM3/AM3+ as well as FM1/2/2+.

Gaming Computer

DDR3 RAM is important for your gaming system as it can access data quicker than retrieving it from the storage disk. Think of RAM as your desk, and main storage as your file cabinet. It’s tedious to go to your filing cabinet to get files every time you need something new to work on. If you have a proper RAM like DDR3, you can keep as many files you need on your desk and retrieve them in quick successions. 

For a gaming PC, this is very crucial. With low storage, you get poor and slow performance, as well as a choppy frame rate. DDR3 makes your gaming PC the best gaming PC ever.
