8GB VS 16GB RAM 2018 PCIntegrated versus discrete graphicsĪnother consideration when configuring RAM is what kind of graphics hardware your PC will use. And, most notebooks today max out at 16GB of RAM, meaning that your notebook options will be limited if you need to configure it with 32GB of RAM or more. That means picking a desktop with enough RAM slots that support large enough DIMMs. 8GB VS 16GB RAM 2018 INSTALLIn addition, you’ll want to make sure that your chosen PC can install the amount of RAM that you need. That complicates the decision about how much RAM to purchase – if you pick a notebook that doesn’t have enough RAM, then it’s never going to be able to provide the necessary performance. ![]() Many notebooks today are tightly sealed and cannot be upgraded, meaning that the amount of RAM that you select when buying the notebook is what you’re stuck with for its lifespan. ![]() Some notebooks use DIMMs, while others have the RAM directly soldered onto the motherboard. You can also swap RAM out as needed up to the limits of what the motherboard can accept. If you’re building your PC, then you can just use some of the available RAM slots, and leave some open for adding more RAM later. And RAM DIMMs come in various sizes, from under one gigabyte (1GB) all the way up to 64GB versions, with motherboards accepting a range of RAM capacities. 8GB VS 16GB RAM 2018 HOW TODesktop motherboards ( check out our guide on how to choose a motherboard here) have multiple RAM slots, typically between two and eight. What’s important to remember here is that the RAM in desktop PCs can easily be increased or decreased. We won’t dig into the details, but most RAM that you purchase for a desktop will be some speed of DDR4 RAM while the RAM that’s equipped in the typical notebook PC will be either DDR3 or DDR4 RAM. In turn, most RAM today uses a double data rate (DDR) interface, and current popular standards are DDR3 and DDR4. Most RAM today comes in the form of dual in-line memory modules (DIMMs) that hold memory chips adding up to a specific amount of RAM. Simply put, it’s probably better to occasionally have “too much” RAM than to not have enough RAM when you need it. We recommend that you consider your worst-case scenarios when deciding on the amount of RAM. Therefore, there’s a balance between spending more money and using more power by equipping more RAM than you need and not having enough RAM for efficient operation.Īs usual with these kinds of configuration questions, the answer depends entirely on how you want to use your PC. So with all of that said: how much RAM do you need? That is, how much RAM is necessary to keep your PC running smoothly and to minimize the use of swap files? RAM costs money, and it uses a small amount of power, which is a consideration for notebooks that need to run on batteries. While the information that the system isn’t actively using can be written to storage in “swap files” when there’s too much to store in RAM, the process of constantly switching information to and from storage is slower than working with it directly in RAM. ![]() All the information that your OS and applications need to use while actively processing needs to be available in RAM. The amount of RAM that you use in your PC is an important element in how well it will perform. That’s why there’s also long-term storage such as hard disk drives (HDDs) and solid-state drives SDDs) for saving information when the power is turned off. Turn off the PC, on purpose or accidentally (as happens with a power failure), and all the contents of RAM are lost. RAM is “volatile” memory, meaning that it only maintains information while it’s receiving power. ![]() Prices and availability of products discussed were accurate at time of publication, but are subject to change. It’s where the operating system (OS) loads when the PC is turned on and booted up, and it’s where applications run and store their information during active processing. In this piece, we’re going to cover random-access memory (RAM), which you can think of as the PC’s short-term memory. There’s the central processing unit (CPU), the graphics processing unit (GPU), memory, storage, display, and various others that are all vital to getting things done with a PC. Every personal computer is made up of several components that combine to run the applications that make the PC such a useful tool.
