While RAM will help the Web browser run, it won't have a direct impact on Internet speed. Whether or not an upgrade in RAM will make the browser work better depends on how much memory is already in the system. If you already have more than enough memory to run the browser, an upgrade will have little to no effect.

Does the Internet use RAM?

RAM exists to make your computer faster. Your computer uses RAM as a cache to store things it may need again soon—in the case of web browsers, that could be web pages or other resources used by plug-ins and extensions. That way, when you go back to that web page or use that extension again, it'll load faster.

Does more RAM help download speed?

Generally, the faster the RAM, the faster the processing speed. With faster RAM, you increase the speed at which memory transfers information to other components. Meaning, your fast processor now has an equally fast way of talking to the other components, making your computer much more efficient.
