Rather than storing data permanently like in large capacity hard drives, RAM provides a temporary cache that your system uses to store the data that you are currently using. This makes accessing the most relevant data much faster, because accessing RAM requires much less time than your hard drive. In fact, most systems are configured to use the hard drive as a substitute for RAM when the RAM is being overloaded with data. This can bring your PC to a crawl, however, and is why having enough RAM is crucial.

DDR3 RAM has been the predominant RAM technology for a good few years now, and its cheapness and high performance are the reason. However, with DDR4 nearly here, and well set to become the motherboard standard, the remaining lifespan of DDR3 RAM is ever shortening.

With a total memory of 16GB, the PNY 16GB Kit (4 x 4GB) 16 Quad Channel Kit DDR3 2133 (PC3 17000) 240-Pin DDR3 SDRAM MD16384K4D3-2133-X10 has the capacity to help run a huge array of applications or a very effective server. It goes above and beyond any gaming or general PC usage requirements, and can push the performance of applications like Photoshop - that can utilize a huge amount of designated memory - to the extreme. This PNY DDR3 RAM has a speed of 2133MHz. RAM speed is not a crucial feature, but it does contribute significantly to PC games and certain applications like video-editing software. 2133MHz is among the fastest speeds available on the market, so this RAM will exhibit superb performance helping to run either of these.
